AssertionError: Egg-link .. does not match installed location of ReviewBoard (at /...)

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?

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.

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.

Alternatively, you can delete the egg-info folder, and running `pip install -r requirements.txt` after that will add it to the location specified – Ed Harrod Nov 06 '17 at 10:52
Another egg-link path: `/usr/local/Cellar/python3/3.6.1/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/[package].egg-link` – ahuigo May 31 '18 at 14:33

The interesting path on my Ubuntu system was `~/.local/lib/python3.5/site-packages` – Martin Thoma Sep 25 '18 at 09:30

You can silence the AssertionError by running Python in optimized mode, -O. And we can run the pip module through Python too, -m.

$ python -O -m pip uninstall <pkg-name>

Note: You may want to verify python -m pip is the same as pip. As sometimes the default Python and default pip can get out of sync.

$ pip -V
pip 20.3.1 from /usr/lib/python3.9/site-packages/pip (python 3.9)
$ python -m pip -V
pip 20.3.1 from /usr/lib/python3.9/site-packages/pip (python 3.9)

Running -O uninstall prompted me to remove the egg-link just like rm. Nice straightforward alternative. Thanks! – 0xDBFB7 Jul 23 '22 at 19:38
Running with `-O` skips all assertions. Not sure why pip contains such an assertion, but strangely this fixes it. – Teque5 Sep 12 '22 at 17:02
@Teque5 Why do you think pip shouldn't assert the file system is in the expected state before performing a dangerous operation? – Peilonrayz Sep 12 '22 at 17:05
@Peilonrayz The user is trying to remove a link. The target of the broken link doesn't exist. `pip` *should* attempt to remove the link, regardless if the target exists or not. The choice to assert an Error forces us to google a solution ∴ the assert should not exist. – Teque5 Sep 13 '22 at 20:21

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.

I had to remove the `python*` and pass in my interpreter-prefix (dirpath of sys.executable for the virtualenv), since I am using pexpect/wexpect to automate the updating of many virtualenvs and not actually using the virtualenv to uninstall things inside it. Additionally, I added a new arg to control whether I wanted to delete the EGG or the PTH file (since both seem necessary to delete if present). – nmz787 Aug 26 '20 at 10:07

Just delete your .tox folder. When you run tox again a new .tox/ directory gets generated with the correct paths.

I fixed this by upgrading pip from 6 to 9.
