0.9.9: anyconfig .dist-info directory not found #110

pip3 install anyconfig fails with:

WARNING: Running pip install with root privileges is generally not a good idea. Try `pip3 install --user` instead.

This is happening with pip 9.0.3, which happens to be the default version installed on the new rhel8.

Package metadata should be adapted so installation failure does not happen, even if pip is not the latest and greatest.

What makes this problem even worse is that if user attempts to upgrade pip with pip, it will rended pip unusable:

# pip3 install -U pip

This happens because pip installs exec into /usr/local/bin/pip3 but system has it under /usr/bin/pip3 and the shim script uses an old import method which crashes the old launcher.

Even afther finding workarounds to run with latest pip (19.2.1), I still get the same error.

The problem happens with 0.9.9 and 0.9.8 versions, but i was able to install 0.9.7 without problems. Clearly the project needs a test which validates that package is installable with pip 9.0.1 (even if not even older than this).

Thanks a lot for your report!

I changed to use setup.cfg since 0.9.8 and it might cause the problem. I'll dig into it this weekend.

@ssato Anychance of solving this? I keep getting into conflicts where Anyconfig 0.9.9 gets installed and breaks even when I mentioned anyconfig==0.9.7, the last one that had a valid metadata.

ssato commented 5 years ago

I'm not sure this issue was resolved but tried that and uploaded the 0.9.10. Could you please try it?

@ssbarnea Can you still reproduce this with anyconfig 0.9.10?
