AssertionError: Egg-link .. does not match install

Question

AssertionError: Egg-link /home/daniel/other-rb/reviewboard does not match installed location of ReviewBoard (at /home/daniel/reviewboard)

I believe this was caused by me installing a package at an additional location using the same virtualenv.

How can I fix this problem? I'm guessing I need to redirect the Egg-link to match the installed location?

Answer 1

If you are using Python3.5 on Ubuntu:

rm ~/.local/lib/python3.5/site-packages/[Package name].egg-link

where [Package name] is the package that causes issues.

Answer 2

If you're building your package with Python

import glob
import os
import sys

def get_egg_file(module_name):
    def f(packages):
        return glob.glob(
            os.path.join(os.path.dirname(os.path.dirname(sys.executable)),
                         'lib', 'python*', packages, module_name + '.egg-link'))

    return f('site-packages') or f('dist-packages')


egg_file = get_egg_file('YOUR_PACKAGE_NAME')
if egg_file:
    os.remove(egg_file[0])

Note that this should be executed in the target virtualenv or system python environment for sys.executable to resolve to what you want.

Answer 3

I fixed this by upgrading pip from 6 to 9.

Answer 4

This problem happens if you move the source code directory after the egg-link file is created.

You can edit the proper egg-link file, /home/daniel/envs/reviewboard-3.0/local/lib/python2.7/site-packages/ReviewBoard.egg-link, replacing the line /home/daniel/other-rb/reviewboard with /home/daniel/reviewboard and retry.
