Cannot install editable package

I wanted to install a package on a local drive as an editable package under Windows:

D:\projects\myproject>pipenv install -e D:\projects\DjangoApps\mypackage

Describe your environment

1. OS: Windows 10 Pro, 64 bit
2. Python version: Python 3.6.1
3. Pipenv version: pipenv, version 8.3.2

Expected result

the package is listed in Pipfile and myproject finds the mypackage dependency

Actual result

The following error occurs:

Installing -e D:\projects\DjangoApps\mypackage…

    st = os.stat(path)
TypeError: stat: path should be string, bytes, os.PathLike or integer, not NoneType  

Solution

I checked the code in pyenv/utils.py and at the line 547, i.e. around:

[...]
  if (req.uri or (os.path.isfile(req.path) if req.path else False) or
        os.path.isfile(req.name)) and not req.vcs:
[...]

the error occurs because req.name is None. Hence the simple solution is check as for req.path:

if (req.uri or (os.path.isfile(req.path) if req.path else False) or
        (os.path.isfile(req.name) if req.name else False)) and not req.vcs:

At least on my pc it worked. The Pipfile looks as follows after installing the editable package:

[packages] … django = “==1.10.5” “-e d:\projects\djangoapps\mypackage” = “*”

@chenull pipenv version 9.0 has been released with this fix, so I’m going to close this issue – let us know if there is any further problem!

[techalchemy]

@chenull that should be right, the fix from #958 hasn’t found its way into a release yet since things were in a bit of a freeze due to needing to put together a major release. I suspect we’ll see one soon
