Problems with pip

[bitboxer]

Looks like pip does not like the --user argument when updating itself anymore. I am getting this error when using exogenesis:

Exception:

Storing debug log for failure in /Users/bodo/.pip/pip.log

And when I try it on the console and leave out the --user, it works. With it, it stops with this message.

pip is driving me insane...

You are not the only one with that problem :sob:

So: same here :cry:

[thegcat]

Mmh, completely removing the homebrew python (brew uninstall python && rm -rf $(brew --prefix)/lib/pythonX.Y/site-packages for 2.7), reinstalling it ad applying the ~/.pydistutils.cfg described in https://github.com/Homebrew/homebrew/blob/master/share/doc/homebrew/Homebrew-and-Python.md#note-on-pip-install---user seem to work for me.

[moonglum]

Phew. Thanks for investigating :heart:

[bitboxer]

Yes, this works. Should we add the pydistutils.cfg during the setup phase? This could be dangerous :flushed:

[moonglum]

I would say: No.

[bitboxer]

So what else could we do for our users? Check for this error and output a hint that helps to fix this?

[moonglum]

Yes, I think that would be the best option!
