python initialisation not working

[Catherine Pitt]

An init script for using environment modules inside python is available in the package but it doesn't work for me.

For example:

$ python
Python 2.7.6 (default, Jan 12 2014, 08:16:39)
[GCC 4.8.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> execfile('/usr/share/modules/init/python.py')
>>> module('list')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/share/modules/init/python.py", line 27, in module
    (output, error) = subprocess.Popen(['/usr/bin/modulecmd' % os.environ['MODULE_VERSION'], 'python'] +
TypeError: not all arguments converted during string formatting

when I was expecting this:

$ python
Python 2.7.6 (default, Jan 12 2014, 08:16:39)
[GCC 4.8.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> execfile('/usr/share/modules/init/python.py')
>>> module('list')
Currently Loaded Modulefiles:
>>>

Here are the versions I'm using

$ lsb_release -rd
Description: Ubuntu Trusty Tahr (development branch)
Release: 14.04

$ apt-cache policy environment-modules
environment-modules:
  Installed: 3.2.10-8
  Candidate: 3.2.10-8
  Version table:
 *** 3.2.10-8 0
        500 http://www-uxsup.csx.cam.ac.uk/pub/linux/ubuntu/ trusty/universe amd64 Packages
        100 /var/lib/dpkg/status

A small change to the init script /usr/share/modules/init.python.py fixes this, I attach a diff.

Thanks for taking your time to report this issue and help making Ubuntu better.

I got the same error message when following the steps to reproduce this issue on Ubuntu Trusty.

I also noticed that the attachement was not flagged as a patch, so I've checked the patch flag for it. In the future when submitting patches please use the patch checkbox as there are some Launchpad searches that use this feature. You can learn more about the patch workflow at https://wiki.ubuntu.com/Bugs/Patches.

The attachment "fix-python-init" seems to be a patch. If it isn't, please remove the "patch" flag from the attachment, remove the "patch" tag, and if you are a member of the ~ubuntu-reviewers, unsubscribe the team.
