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?

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.

Tobolsk

Answer 2

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.

Physician

Alternatively, you can delete the egg-info folder, and running pip install -r requirements.txt after that will add it to the location specified – Signboard

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 – Herschel

The interesting path on my Ubuntu system was ~/.local/lib/python3.5/site-packages – Tobolsk

Answer 3

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! – Hematite

Running with -O skips all assertions. Not sure why pip contains such an assertion, but strangely this fixes it. – Pupiparous

@Pupiparous Why do you think pip shouldn't assert the file system is in the expected state before performing a dangerous operation? – Hypoblast

@Hypoblast 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. – Pupiparous

Answer 4

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). – Appetizing

Answer 5

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

Answer 6

I fixed this by upgrading pip from 6 to 9.
