Issue #119 new

distribute reinstalls packages from system site-packages when using virtualenv

Ralf Schmitt
created an issue

I have a fresh install of python 2.6.4 in /opt/py26/ installed as root. As root I now also install the lockfile module with

$ /opt/py26/bin/python setup.py install

As user I create a virtualenv with

/opt/py26/bin/python virtualenv.py ~/py26 --distribute

Now I run

~/py26/bin/easy_install lockfile

which tries to download the lockfile module and installs it in my virtualenv. If I remove the --distribute option, setuptools recognizes the old installation of the lockfile module in /opt/py26/... and does not reinstall it.

    The following patch fixed it for me:

    diff --git a/setuptools/command/easy_install.py b/setuptools/command/easy_install.py

    It sounds like a good way to test installations, but I guess that's only relevant if it is a newer version. Adding all of sys.path sounds like a big addition though. This probably needs to be discussed on distutils-sig.
