Delete all virtualenv and start from scratch

问题

I used to use macport and recently switch to homebrew. After cleaning up all the macports enviornments using python version installed by homebrew I did pip install virtualenv.

$virtualenv test --no-site-packages
Traceback (most recent call last):
  File "/usr/local/bin/virtualenv", 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: virtualenv==1.9.1

I also check what virtualenv are available in the system, it was bit confusing to see

$virtualenv
virtualenv      virtualenv-2.6

SO I uninstall what I installed and then tried to do a reinstall:

Requirement already satisfied (use --upgrade to upgrade): virtualenv in /usr/local/lib/python2.7/site-packages
-bash: syntax error near unexpected token `('

I checked how the structure looks like in /usr/local/bin: I don't think any of these virtualenv(s) are symlinks:

-rwxr-xr-x    1 root  wheel       276 Mar 12  2013 virtualenv
-rwxr-xr-x    1 root  wheel       284 Mar 12  2013 virtualenv-2.6

How can I delete all virtualenv, and start from scratch?

回答1:

After uninstalling everything and removing all the virtualenv, I was able to successfully install. Just incase if you have

~/.pydistutils.cfg
