I've been using PyDev within Eclipse on my Mac for about two years now. Updated Eclipse today, and suddenly PyDev is completely missing. Tried everything, included a complete uninstall and fresh install, but although PyDev shows up as installed in the menu, it appears nowhere else.

PyDev version: 3.0.0.201311051910 Eclipse: Version: Kepler Service Release 1 Build id: 20130919-0819

I can't open a PyDev perspective, I can't create a new Python file, and I can't open an existing Python file without it just being seen as plain text.

I've got a huge assignment due tonight, help appreciated.


To see what the problem is, I upgraded from PyDev 2.8.2 to 3.0.0 just for this. It caused me a world of hurt. That version is filled with bugs. Nothing is working for me, including the perspectives or the debugger. I just went back to 2.8.2 and all is well again. I am also on Kepler and Mac. Go to 2.8.2. YOu can uninstall pydev using eclipse, then simply install pydev using the easy zip file instructions here: http://pydev.org/manual_101_install.html.

3.0.0 was just released yesterday. They obviously have some fixing to do!


Not enough rep to comment on Tobx's answer so I'll make a new one.

You can install java7 but retain your current version and not affect your current set up by specifying which JVM Eclipse should use using the command line -vm option.

All is explained here


I debugged a python project (imported before). The Pydev menu has reappeared by only changing the current perspective to "Debug".

I think opening the Pydev perspective through Window > Open Perspective > Other ... > Pydev would also create the Pydev menu.


The following solved the problem for me, on OS X Mavericks 10.9.2 initially with Java 1.7.0_55 (from Oracle, the standard Mavericks install I think, fully up to date)

  • check the available Java virtual machines using the terminal :

/usr/libexec/java_home -V

I initially only had Java 1.6 listed here (a similar check from within Eclipse also confirmed that it was running 1.6, not the available 1.7 !)


It seems a lot of PyDev/Eclipse issues are a matter of using the correct Java JRE/JDK and PyDev for the version of Eclipse you're running.

From http://www.pydev.org/

Release 5.2.0

Important PyDev now requires Java 8 and Eclipse 4.5 onwards.

PyDev 4.5.5 is the last release supporting Java 7 and Eclipse 3.8. See: update sites page (http://www.pydev.org/update_sites/index.html) for the update site of older versions of PyDev.


At start i was also facing same error that : The solution is not provide while installing PyDev - Python IDE for Eclipse 6.3.2 and when I am When trying to install I receive the following message: Unable to read repository at https://dl.bintray.com/fabioz/pydev/latest/content.xml. ?

Then i came up with the final solution :

follow the steps :

Online Install

The URL for installation of the feature is http://pydev.org/updates. You can use that URL to Install New Software... from the Help menu if the Eclipse Marketplace is not doing what you want.

and uncheck all the options mentioned below on Install New Software Window like: Uncheck :

1.Show only the latest versions of available software
2.Group Items by category
3.Show only software applicable to target environment
4.Contact all update sites during install to find required software

Offline Install

If you meet the requirements (below) and continue to have problems with the update site, you can download to install offline. Get it from SourceForge (or follow the link from PyDev's website to SourceForge).

and uncheck all the options mentioned below on Install New Software Window like: Uncheck :

1.Show only the latest versions of available software
2.Group Items by category
3.Show only software applicable to target environment
4.Contact all update sites during install to find required software

![Kepler Pydev config] I had to spend lot of time to figure out why it is not working. But ultimately did. Download 2.8.2 zip instead and unzip in dropins folder as shown. Start eclipse with -clean option


I order to have access to each parameter value, the following code may be helpful.

import argparse
parser = argparse.ArgumentParser()
parser.add_argument('-a', '--arg', nargs='+', type=int)
args = vars(parser.parse_args())

print "first parameter:" + str(args["arg"][0])
print "second parameter:" + str(args["arg"][1])
print "third parameter:" + str(args["arg"][2])
