bzt 1.1.0 says DistributionNotFound: selenium
Question: I just installed bzt 1.1.0 on my MacOSX but it won't run, it gives this
message:

    
    
    Traceback (most recent call last):
      File "/usr/local/bin/bzt", line 5, in <module>
        from pkg_resources import load_entry_point
      File "/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/pkg_resources.py", line 2603, in <module>
        working_set.require(__requires__)
      File "/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/pkg_resources.py", line 666, in require
        needed = self.resolve(parse_requirements(requirements))
      File "/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/pkg_resources.py", line 565, in resolve
        raise DistributionNotFound(req)  # XXX put more info here
    pkg_resources.DistributionNotFound: selenium
    

The thing is, selenium 2.49.2 was installed along with bzt. How can I fix
this?


Answer: Turns out it was a Python package management issue. Selenium was installed in
/Library/Python/2.7/site-packages with a `selenium-2.49.2.dist-info`
directory, not the `.egg-info` directory that `pkg_resources.py` expected.

Upgrading to a newer version of pkg_resources helped, as explained in [this
answer](http://stackoverflow.com/a/21175750/584846):

    
    
    sudo pip install --upgrade setuptools
    

Then, reinstalling selenium finally fixed the problem:

    
    
    sudo pip uninstall selenium
    sudo pip install selenium
