pip 10.0.1 install -e . fails when install.user is set in the config

[anntzer]

(setup is nearly a copy-paste of #5085)

• Pip version: 10.0.1
• Python version: 3.6
• Operating system: Arch Linux

Description:

Tried to editably install a local project using pyproject.toml while the install.user key is set in ~/.config/pip/pip.conf. Failed with the traceback below.

What I've run:

$ cat setup.py
from setuptools import setup
setup(name="foobarbaz")

$ cat pyproject.toml
[build-system]
requires = ["setuptools", "wheel"]

$ cat ~/.config/pip/pip.conf
[install]
user = true

$ pip install -e .

As a side note, note also the spurious error message: Found existing installation: foobarbaz 0.0.0 Can't uninstall 'foobarbaz'. No files were found to uninstall.. There is actually no installation of foobarbaz either in my system or user site packages.

Hi @anntzer! Thanks for filing this issue.

@benoit-pierre Do you by any chance have the time to look into this?

[benoit-pierre]

The problem is that when the user site is disabled (as with python -s ..., and our build isolation), support for the --user option is disabled by setuptools...

Is there a way around this?
The issue arises also when specifying --user on the command line:

$ git clone https://github.com/godby-group/idea-public
$ cd idea-public
$ pip install --user -e .

However, when I run the command that is supposed to fail, it works:

$ /usr/bin/python -c "import setuptools, tokenize;__file__='/home/max/idea-public/setup.py';f=getattr(tokenize, 'open', open)(__file__);code=f.read().replace('\r\n', '\n');f.close();exec(compile(code, __file__, 'exec'))" develop --no-deps --user --prefix=
...

Is there some way around this?

New solution! Nuke your ~/.local/lib/python3.6/

mv ~/.local/lib/python3.6/ ~/.local/lib/python3.6.bak

For the fearless

rm -rf ~/.local/lib/python3.6/

This worked for me, being that i never touch anything globally (pip in PATH is now back to 9.0.1)
