OS X virtualenv Handling is Broken

[peblair]

When running hatch install -l, the following error appears:

Installing...
Obtaining file:///Users/pblair/views/test-project
Installing collected packages: test-project
  Running setup.py develop for test-project
    Complete output from command /opt/local/bin/python3 -c "import setuptools, tokenize;__file__='/Users/pblair/views/test-project/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:
    running develop
    error: can't create or remove files in install directory

    The following error occurred while trying to add or remove files in the
    installation directory:

        [Errno 13] Permission denied: '/opt/local/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/test-easy-install-67789.write-test'

    The installation directory you specified (via --install-dir, --prefix, or
    the distutils default setting) was:

        /opt/local/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/

    Perhaps your account does not have write access to this directory?  If the
    installation directory is a system-owned directory, you may need to sign in
    as the administrator or "root" account.  If you do not have administrative
    access to this machine, you may wish to choose a different installation
    directory, preferably one that is listed in your PYTHONPATH environment
    variable.

    For information on other options, you may wish to consult the
    documentation at:

      https://setuptools.readthedocs.io/en/latest/easy_install.html

    Please make the appropriate changes for your system and try again.

The problem appears to be in the virutualenv handling:

 λ test-project git:(master) ✗ > hatch shell . pip --version
Running `pip --version` in this project's env...
pip 9.0.1 from /opt/local/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages (python 3.6)
 λ test-project git:(master) ✗ > . ./venv/bin/activate && pip --version && deactivate
pip 9.0.1 from /Users/pblair/views/test-project/venv/lib/python3.6/site-packages (python 3.6)
 λ test-project git:(master) ✗ >

Further investigation seems to indicate that the culprit is the __PYENV_LAUNCHER__ variable:

 λ test-project git:(master) ✗ > hatch shell . env | grep LAUNCHER
__PYVENV_LAUNCHER__=/opt/local/bin/python3
 λ test-project git:(master) ✗ > . ./venv/bin/activate && (env | grep LAUNCHER) && deactivate

And, sure enough, unsetting it manually fixes the issue:

 λ test-project git:(master) ✗ > hatch shell .
source "/Users/pblair/views/test-project/venv/bin/activate"
 λ test-project git:(master) ✗ > source "/Users/pblair/views/test-project/venv/bin/activate"
(venv) λ test-project git:(master) ✗ > pip --version
pip 9.0.1 from /opt/local/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages (python 3.6)
(venv) λ test-project git:(master) ✗ > unset __PYVENV_LAUNCHER__
(venv) λ test-project git:(master) ✗ > env | grep LAUNCHER
(venv) λ test-project git:(master) ✗ > pip --version
pip 9.0.1 from /Users/pblair/views/test-project/venv/lib/python3.6/site-packages (python 3.6)
(venv) λ test-project git:(master) ✗ >

Would it be possible to add a del os.environ["__PYVENV_LAUNCHER__"] in the venv code to remedy this problem?

Found this too https://bugs.python.org/issue22490

I'm working on it now!

@belph Please try fix in 0.17.1 and let me know!

[peblair]

Yes, that seems to have fixed it. Thank you!

[ofek]

Yay, thanks for the report!
