[Pydev-users] [Users] Infinite loop when setting up Jython

[SourceForge.net <no...@so...>]

The following forum message was posted by pkeller at http://sourceforge.net/projects/pydev/forums/forum/293649/topic/4598725:

[code]OS: openSUSE 11.4
Eclipse version: Helios SR1
PyDev version 2.2.0
Jython version: 2.2a0[/code]

I tried to add a jython interpreter, using [code]/usr/share/java/jython.jar[/code]
as the interpreter. When I clicked "OK", an error window appeared that contained
the following message:

[quote]It seems that the Python /Lib folder (which contains the standard library)
was not found/selected during the install process or the stdlib does not contain
the required .py files (i.e.: only has .pyc files).

This folder (which contains files such as threading.py and traceback.py) is
required for PyDev to function properly (and it must contain the actual source
files, not only .pyc files).

Note that if this is a virtualenv install, the /Lib folder from the base install
needs to be selected (unlike the site-packages which is optional).[/quote]

Clicking on "OK" in this window just brings it back. I tried clicking "OK"
repeatedly, hoping that it would try a finite number of times and then give
up, allowing me to specify the directory by hand, but this didn't work. In the
end, I had to use xkill to kill this window, which terminated eclipse as well
of course.

First point: am I right in thinking that this is a bug in PyDev? Even if the
Jython installation is odd in some way, at least there should be a way past
this point so that I can tell it where to look for the required files if it
can't find them on its own?

Second point, the required files do seem to me to be present:
