Answer 2

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

Answer 3

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!

Answer 4

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 !)

• following posts suggesting that I had the Java 7 JRE but not the JDK, I installed the JDK from Oracle : http://www.oracle.com/technetwork/java/javase/downloads/jdk7-downloads-1880260.html

• then checked again /usr/libexec/java_home -V ... and hurrah! 1.7 showing up !

• Restarted Eclipse... didn't change anything else : the previously installed PyDev started to work (just had to re-open files in the editor)

Answer 5

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.

Answer 6

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.
