I tried to run pywikibot in tools web server and got an error:

  File "/shared/pywikipedia/core/pywikibot/version.py", line 134, in getversion_git
    except WindowsError:
NameError: global name 'WindowsError' is not defined

The problem comes from:

   cmd = 'git'
    try:
        subprocess.Popen([cmd], stdout=subprocess.PIPE).communicate()
    except WindowsError:

The framework tries to call git, but /usr/bin is not in $PATH in tools web server; consequently, the calling fails. The error falls to except block, and obviously, tools server is not Windows; WindowsError is not defined, making NameError.
