Problem with python2 distutils after recent update [SOLVED]

TheStatsMan · 2012-05-12 01:42:59

Hi,

I regularly use f2py2 to compile fortran code to use with Python2. I am currently up to date running Python 2.7.3. Anyway, f2py2 recently stopped working. As an example if I try

[chris@chris pymcmc5]$ f2py2 -c matutil.f -m matutil
Traceback (most recent call last):
  File "/usr/bin/f2py2", line 24, in <module>
    main()
  File "/usr/lib/python2.7/site-packages/numpy/f2py/f2py2e.py", line 588, in main
    run_compile()
  File "/usr/lib/python2.7/site-packages/numpy/f2py/f2py2e.py", line 530, in run_compile
    from numpy.distutils.system_info import get_info
  File "/usr/lib/python2.7/site-packages/numpy/distutils/system_info.py", line 125, in <module>
    from distutils.dist import Distribution
  File "/usr/lib/python2.7/distutils/dist.py", line 10, in <module>
    from email import message_from_file
ImportError: cannot import name message_from_file

The problem, as can be seen from the output appears when trying to import Distribution from distutils.dist. I get the same error if from Ipython2 I try

from distutils.dist import Distribution

I am not sure what I should do to address this issue. I do need f2py2 for my work though so am desparate for a solution. If any more information is required please let me know.

First, try reinstalling python2.7. If that doesn't fix it, upload /usr/lib/python2.7/email/__init__.py.

Thanks for the suggestions. I reinstalled python2.7. This didn't help unfortunately.

here is my /usr/lib/python2.7/email/__init__.py

Is this what you meant by uploading the file?

What happens when you run `from email import message_from_file` and `from email import message_from_string`.

I just tried both. It seemed to work fine, no errors popped up.

This issue seems to have been fixed in the latest update.
