Eclipse For Python Download Mac

Topics

Python, Pydev and Eclipse. This article describes how to write and debug Python programs with Eclipse This article is based on Eclipse 4.3, Python 3.3.1 and PyDev version 2.7.3.

Note:

This document refers to Eclipse 4.7 (Oxygen) for Windows, the most current version as of this writing. Note that different computer set ups and themes may mean that the appearance of the screen shots in this document may not match exactly your computer system. In particular, the Mac version of Eclipse looks significantly different, although it has the same functionality as the Windows version.

PyDev (Python Development Environment) is a plugin that enables users to use Eclipse for Python development -- making Eclipse a first class Python IDE (Integrated Development Environment) -- It comes with many goodies such as code completion, syntax highlighting, syntax analysis, refactoring, debug and many others

From http://pydev.org/

Pydev requires that you first install a Python interpreter and the Eclipse integrated development environment. Pydev is a plugin for Eclipse and cannot be used without having both Python and Eclipse installed.

Installing Python

Download the latest version of the Python interpreter from http://www.python.org/download/. Choose the version appropriate to your computer. For Windows users you may choose Windows x86 (32 bit) or Windows x86-64 (64 bit). If you are unsure whether your particular PC supports 64 bit programs or not, choose standard Windows x86. Note where on your system you installed Python as you must know this when configuring Pydev. For the Mac choose the 64 bit version at all times.

As of this writing the latest version of Python available is 3.4.1.

Installing Eclipse

See Installing Eclipse.

Installing Pydev

Install Pydev by following the instructions in the Installing Plug-ins section of Installing Eclipse. The installation URL to enter into Eclipse's Install dialog box for Pydev is:

http://pydev.org/updates

As of this writing the latest version of Pydev available is 3.7.1

Configuring Pydev

Pydev must be configured in order to work properly with your Eclipse and Python set ups. From the Eclipse main menu choose Window / Preferences. (For the Mac choose Eclipse / Preferences). This brings up the Preferences dialog box. Choose Pydev / Interpreter - Python:

The Quick Auto-Config may set Eclipse up the way you want it, but only if some version of Python 3 is selected. If no version of Python is found, follow the next steps. If an earlier version of Python is found, make sure that you remove it with the Remove button and follow the next steps.

Press the New button, and from the Select Interpreter name the interpreter (ex: Python) and browse to the the location of your python.exe file and select it. (The Python interpreter should be located wherever you installed Python on your system.) The following is an example of what the selected name and interpreter may look like:

Naming and selecting the Python interpreter brings up the Selection Needed dialog box:

Accept the default selections and press OK. The Preferences dialog box now shows the Python interpreter and libraries that you selected. Press OK to accept these values. Eclipse will take a moment to process these selections. You may now start programming in Python.

For Mac Users

Windows places all Python files in one place. Mac OS 10 splits the Python installation into two areas. The installation under System seems to be just user interface files. The actual Python executable that you must enter in the Select interpreter dialog box is at one of:

/Library/Frameworks/Python.framework/Versions/3.4/bin/python3.3
/System/Library/Frameworks/Python.framework/Versions/3.4/bin/python3.3

This varies depending on the version of Mac OS you are running.

Adding Libraries

The Python interpreter ships with a number of libraries, such as the math library, already installed. Other Python applications and programs may require further external libraries and you may add these libraries to your Pydev set up.

To add a library to the Pydev installation, open the Preferences dialog box. (You used this item in the previous section to set up the Python interpreter.) This time you must add folders to the System PYTHONPATH. To do so press the New Folder button, and then browse to the folder containing the libraries you wish to add. After selecting the folder containing the new Python library press OK to confirm the selection.

Install Python before installing Eclipse.

You may want to print these instructions before proceeding, so that you can refer to them while downloading and installing Eclipse. Or, just keep this document in your browser. You should read each step completely before performing the action that it describes. This document shows downloading and installing Eclipse (Luna). You should download and install the latest version of Eclipse. The current latest (as of Fall 2018) is Eclipse 2018-09.

Eclipse Ide For Python

Eclipse: Luna

The Eclipse download requires about 200 MB of disk space; keep it on your machine, in case you need to re-install Eclipse. When installed, Eclipse requires an additional 200 MB of disk space.

Downloading

1. Click Eclipse

   The following page will appear in your browser. In this handout we will download Eclipse Standard 4.4 for Mac OS. The version you should download is Eclipse IDE for Eclipse Committers.

   It is critical that Java, Python, and Eclipse are either all 32 Bit or are all 64 Bit (and only if your Machine/OS supports 64 Bit): I think it easiest on Macs to use 64 Bit for everything.

2. Click the 64-bit after Mac Cocoa for your machine, to the right of Eclipse Standard 4.4 (right under Eclipse Luna R Packages).

   You will see the following page (don't worry about the name of the institution to the right of the big downward pointing arrow).

3. Click the big downward pointing arrow underneath the Download eclipse-standard-luna-R-macosx-cocoa-x86_64.tar.gz from: The site named here, in purple to the right of the arrow: [United States] ibiblio (http) is the random one chosen by the download page this time; yours may differ.

   If you see the following pop-up window

   ensure the Save File radio button is depressed and click OK.

   This file should start downloading in your standard download folder. This file is about 200 Mb so it might take a while to download fully if you are on a slow internet connection (it took me a few minutes over a cable modem). Don't worry about the exact time as long as the download continues to make steady progress.

   After the download has finished, terminate the window browsing the Eclipse download.

4. Move this file to a more permanent location, so that you can install Eclipse (and reinstall it later, if necessary).
5. Start the Installing instructions directly below.

Installing (for Python)

Python and Java should be installed before installing Eclipse

Eclipse For Python Windows

1. Unzip eclipse-standard-luna-R-macosx-cocoa-x86_64.tar.gz by double-clicking it.

   Unzipping this file creates a folder named eclipse; unzipping 200 MB can take a few minutes. You can leave this folder here or move it elsewhere on your hard disk.

2. Create an alias on the desktop to to the eclipse file in this eclipse folder:
   On the Mac, you can
   • Control-click the file eclipse.exe
   • Select the Make Alias option.
   • Move it to the desktop.

   Now you are ready to perform a one-time only setup of Eclipse on your machine.

3. Double-click the alias to Eclipse that you just created above.

   If the following pop-up window appears

   click Open.

   The following splash screen will appear

   and then a Workspace Launcher pop-up window will appear.

   In the Workspace text box, your name should appear between /Users and /Documents, instead of ellenolshansky (I did this on my wife's Mac).

   Leave unchecked the Use this as the default and do not ask again box. Although you will use this same workspace for the entire quarter (checking projects in and out of it), it is best to see this Workspace Launcher pop-up window each time you start Eclipse, to remind you where your workspace is located.

   In fact, it is a good idea to create on your desktop an alias to your workspace folder; but you must click OK (see below) before Eclipse creates this folder and you can alias it.

4. Click OK.

   Progress bars will appear as Eclipse loads.

   Eventually the Eclipse workbench will appear with a Welcome tab covering it.

5. Terminate (click X on) the Welcome tab.

   You will not see the Welcome tab when you start Eclipse again, after this first time.

6. Click Help (on the far right of the top toolbar) and then click Install New Software... in its pull-down menu, as shown below.

   The Install pop-up window will appear.

7. Enter the text (or cut/paste from this document) http://pydev.org/updates into the Work with text box and press Enter (if that doesn't work, try http://www.pydev.org/updates).

   In a few seconds the information under Name should change from
   There is no site selected to Pending to

   Select only the top PyDev checkbox; do NOT select the PyDev Mylyn Integration (optional) box.
   Check before proceeding that the Install pop-up window appears as

10. Click Finish

    An Installing Software pop-up window will appear. During installation, it will show the various operations it is performing and a progress bar for each one. Because the installer is fetching various files online, this process might take a few minutes.

    The installation will pause, and a Selection Needed pop-up window appears.

11. Check the box labeled Brainwy Software; Pydev; Brainwy.

    Check before proceeding that the Install pop-up window appears as

12. Click OK

    The installation will finish (showing the final progress bars).

    A Software Updates pop-up window will appear.

13. Click Yes

    Eclipse will terminate and restart. As you did in step 3, click OK to the Workspace Launcher pop-up window.

14. Click Eclipse (to the right of Apple logo on the far left of the top tool bar), and then click Preferences in its pull-down menu, as shown below.
15. Drill down to select the interpreter:
    • Disclose PyDev by clicking the triangle in front of PyDev or double-clicking PyDev (after the triangle).
    • Disclose Interpreters by clicking the triangle in front of Interpreters or double-clicking Interpreters (after the triangle).
    • Select Python - Interpreter.
    The Preferences pop-up window should appear as follows
16. Click New... at the top-right of the top window

    A Select Interpreter pop-up window appears.

    Type python34 in the Interpreter Name text box.
    Type (or cut/paste) //usr/local/bin/python3 in the Interpreter Executable text box (or browse to this file).
    The Select Interpreter pop-up window should appear as

17. Click OK.

    A Selection needed pop-up window will appear.

    Ensure that a check appears in all four checkboxes.

18. Click OK.

    The Preferences pop-up window will be changed to

19. Click OK.

    A Progress Information pop-up window will appear.

    During installation, it will show the various operations it is performing and a progress bar for each one. Eventually the installation will terminate.

20. Click Window (to the left of Help on the far right of the top tool bar), hover over Open Perspective in the pull-down menu and then click Other... in the next pull-down menu.

    The Open Perspective pop-up window will appear.

21. Double-click PyDev (third from the bottom)

    The label on Eclipse will change from Java - Eclipse to PyDev - Eclipse, and the Package Explorer in the upper-left tab will change to PyDev Package Explorer, and a PyDev icon will appear to the right of the Java icon.

22. Right-click the Java icon to the left of the PyDev icon and select close

    The Eclipse workbench will now have only the PyDev icon here and will look like

23. Download the courselib.zip file.

    In the pop-window that appears

    ensure the Save File radio button is depressed and click OK.

24. Locate the workspace folder created in step 3 (see /Users/yourname/Documents/workspace) and copy the courselib.zip file into this workspace and unzip it there, producing the courselib folder; it should should contain a bunch of Python module files (ending in .py). From time to time you will be asked to put other course-specific Python module files into this courselib folder; these modules will be usable in all Python projects in Eclipse.
25. Inform Eclipse to use the courselib folder in all Python projects.
    • Select Eclipse | Preferences.
    • Disclose PyDev by clicking the triangle in front of PyDev or double-clicking PyDev (after the triangle).
    • Disclose Interpreters by clicking the triangle in front of Interpreters or double-clicking Interpreters (after the triangle).
    • Select Python - Interpreter.
    • Click the Libraries tab (leftmost, above the bottom pane)
    • Click the New Folder button (topmost, right of the bottom pane)
    • Browse to the courselib folder (added above) in the Browse for Folder pop-up window (/Users/yourname/documents/workspace/courselib).
    • Click the courselib folder selected, and then click OK
    • Click Apply (you will see some progress bars)
      The < />< />< b=' /> pop-up window should now appear as
