TypeError: coercing to Unicode: need string or buffer, NoneType found

[ghost]

Hi,

I'm trying to install a local setup.py into my virtual environment/Pipfile:

I get this error : TypeError: coercing to Unicode: need string or buffer, NoneType found

Do you have any idea of the problem ?

Thank you in advance

Describe your environment

Mac OS X - Sierra
Python version: 3.6.3

Steps to replicate

brew install pipenv
pipenv --python 3.6.3
pipenv install --dev

Pipfile

[[source]]

url = "https://pypi.python.org/simple"
verify_ssl = true
name = "pypi"

[dev-packages]

keyring = "*"
twine = "*"
"flake8" = "*"
pytest = "*"
"pytest-cov" = "*"

[packages]

requests = "*"
click = "*"

@Germione did you run pipenv install --dev or did you run pipenv install -e . in order to get this error message?

If attempting the latter, try encapsulating it in quotes: pipenv install '-e .'

[craigloftus]

I'm getting the same error with pipenv install -e ~/wagtail-extension, bisecting the versions points to the problem being introduced between 8.2.7 and 8.3.0.

Interestingly, encapsulating like pipenv install "-e /home/craig/wagtail-extensions" will cause the cli help to print, where as pipenv install "-e ~/wagtail-extensions" will trigger the reported error.

I also get the error if installing the above package on its own, like pipenv install --three -e . and pipenv install --three '-e .'.

[craigloftus]

The regression seems to have been introduced in kennethreitz@0a48fa0 which is part of https://github.com/kennethreitz/pipenv/pull/926.

[techalchemy]

@craigloftus thanks for taking the time to dig into that! We actually have a fix implemented already (see #958) that corrects that regression, I’ll see about getting it merged soon

In the meantime for those of you trying to install the local project root as a package you can use the advice here: https://github.com/kennethreitz/pipenv/issues/1012#issuecomment-342898222

On Python 3.6 the error is:

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

@techalchemy @craigloftus : Thanks for your answers
And thanks for the advice: It's working fine !!

[techalchemy]

@bofm thanks for the searchtext :p maybe will reduce the number of issues on this. @Germione thank @AlJohri since it's his fault we even implemented local file install support (#540) and he is still dropping knowledge bombs to support it!

[techalchemy]

This is now resolved in #958
