pipenv shell not changing directory on Windows remote share

[mlodybercik]

Issue description

Using pipenv shell on windows remote share results in new shell spawned not inside the desired folder but inside C:\Windows due to Windows not complying with its own UNC.

Expected result

Z:\path>pipenv shell
Loading .env environment variables…
Launching subshell in virtual environment…
Microsoft Windows [Version 10.0.18363.1016]
(c) 2019 Microsoft Corporation. Wszelkie prawa zastrzeżone.

(urlshortener-J1GJALsb) Z:\path> 

instead of:

Actual result

Z:\path>pipenv shell
Loading .env environment variables…
Launching subshell in virtual environment… 
'\\10.154.201.11\path'
CMD.EXE was started with the above path as the current directory.
UNC paths are not supported.  Defaulting to Windows directory.
Microsoft Windows [Version 10.0.18363.1016]
(c) 2019 Microsoft Corporation. Wszelkie prawa zastrzeżone.
(urlshortener-J1GJALsb) C:\Windows>

Steps to replicate

Create new environment on windows remote share with drive letter.
Run pipenv shell.

I don't think that pipenv --support is needed here, but why not. 🤷‍♀️

[mlodybercik]

I made a quick and dirty hack to pipenv/shells.py to support mounted remote drives.

    def fork(self, venv, cwd, args):
        # FIXME: This isn't necessarily the correct prompt. We should read the
        # actual prompt by peeking into the activation script.
        name = os.path.basename(venv)
        os.environ["VIRTUAL_ENV"] = str(venv)
        if "PROMPT" in os.environ:
            os.environ["PROMPT"] = "({0}) {1}".format(name, os.environ["PROMPT"])
        if "PS1" in os.environ:
            os.environ["PS1"] = "({0}) {1}".format(name, os.environ["PS1"])
        
        with self.inject_path(venv):
            if cwd.startswith("\\\\"):
                import win32net
                drive_letters = {}
                resume = 0
                while True:
                    (_drives, total, resume) = win32net.NetUseEnum(None, 0, resume)
                    for drive in _drives:
                        if drive["local"]:
                            drive_letters[drive["remote"]] = drive["local"]
                    if not resume:
                        break
                remote_share, path = os.path.splitdrive(cwd) 
                new_path = os.path.join(drive_letters[remote_share], path)
                os.chdir(new_path)
                    
            else:
                os.chdir(cwd)
            _handover(self.cmd, self.args + list(args))

[frostming]

The patch LGTM, would you like to send a PR? @krzesu0

[Zzz233]

Same problem on macos，how can i fix it？

[crowdawg]

I see this issue as well with Windows share drives

But this is because CMD.EXE doesn't like UNC paths

pipenv is launching CMD.EXE as default regardless of whether you are currently using it or not.

I always use Powershell and pipenv is launching CMD.EXE inside powershell..

Is there a way to tell pipenv to use powershell as the subshell instead of cmd.exe

This would get around this annoying issue of remote shares as well

[shaenzi]

This still does not work for me, neither in the normal windows shell nor in the Powershell (nor in git bash). Any news on this, or ideas how to circumvent what is actually a problem of the windows shell?

I also found this issue #2295 with the associated pull request from 5 years ago which says it should solve the issue, but that does not seem to be true?

[matteius]

Just merged a community fix: #6322
