OSError when creating virtualenv symlinking in Vagrant

See original GitHub issue

The issue

Using pipenv in a vagrant box is causing a little trouble with the symlinking. It has been requested that --always-copy is added to pipenv when it creates the virtual environment see ( #1929) but it appears that is not gonna happen 😞

The error

Using /usr/bin/python3.6m (3.6.5) to create virtualenv…
Running virtualenv with interpreter /usr/bin/python3.6m
Using base prefix '/usr'
New python executable in /vagrant/project/thing/.venv/bin/python3.6m
Also creating executable in /vagrant/project/thing/.venv/bin/python
Traceback (most recent call last):
  File "/usr/local/lib/python3.6/dist-packages/", line 2349, in <module>
  File "/usr/local/lib/python3.6/dist-packages/", line 712, in main
  File "/usr/local/lib/python3.6/dist-packages/", line 927, in create_environment
    site_packages=site_packages, clear=clear, symlink=symlink))
  File "/usr/local/lib/python3.6/dist-packages/", line 1395, in install_python
    os.symlink(py_executable_base, full_pth)
OSError: [Errno 71] Protocol error: 'python3.6m' -> '/vagrant/project/thing/.venv/bin/python'

Environment variables


commands to fix it

pipenv sync # Fails with OSError listed above
virtualenv --always-copy .venv
pipenv sync # Success!

Seen in vagrant box: ubuntu/xenial64 and ubuntu/bionic64

I hope it helps someone who got stuck with this like I did

@Inveracity I wouldn’t say ‘it appears its not gonna happen’, the issue in question was closed because a simple solution was found that didn’t require api changes on our end. If that’s not true in this case we can revisit it, although I was under the impression that this is automatically toggled for windows virtualenv creation anyway…

Either way, you can also just set the environment variable VIRTUALENV_ALWAYS_COPY=1 and this will be toggled on at creation… closing for now, but let me know if this doesnt work

@uranusjr It is indeed Vagrant running on windows

@techalchemy it works! thank you so much!

tested it doing:

pipenv sync # success
pipenv --rm
pipenv sync # fail as expected
