pipenv clean should ignore and skip entries if they don’t exist

[whren]

Issue description

I'm under WSL 14.04, running python 3.6.6 and upgraded from pipenv 2018.7.1 to the last release, 2018.10.13.

I then try to run a pipenv clean on a virtualenv (existing or new no difference) and I'm getting an error about an include file not found.

It was working before the update of pipenv.

I've located source modification from the stacktrace coming from #2849 with the following commit

Following informations have been anonymised due to client and project informations

Expected result

pipenv clean run successfully without error

Actual result

$ pipenv clean

I modified the title a little to reflect the underlying problem (and how it should be fixed). Thanks for the report and sorry for the trouble.

In addition, I have tried to workaround the issue creating an include empty folder, but I then faced the #3062

Hi @whren,

do you have the Python headers installed for the version of Python you're using in your virtual environment? I noticed that virtualenv (which I think pipenv uses to create the venv) will only create the include dir in the venv if they're installed.

I learned while investigating #3062 that pip clean needs not only for the include dir to exist, but also to contain the Python headers in a directory (or a symlink to a directory). virtualenv will create exactly that, but only if the headers are installed at the time you're creating the venv.

The funny thing is that I never would have noticed this on my Fedora install, because it installs the Python headers by default. But by chance I just noticed that Ubuntu doesn't, and so if I create a venv without installing them, I can reproduce your problem.

If I install python3-dev (or python-dev for Python 2.7) and recreate the venv, it's all good.

Hi @CognexDaniel, very good catch ! I'm under ubuntu on WSL and did not have python 3.6 headers/static libraries installed.

I tried to install libpython3.6-dev and recreated a new virtualenv with a pipenv run pip install pip==18.0.
I confirm the include folder was created with a symlink to the headers files:

$ ls -lh /home/xxx/.local/share/virtualenvs/create-service1-EZvUL_lY/include/
total 0
lrwxrwxrwx 1 xxx xxx 23 oct.  20 11:03 python3.6m -> /usr/include/python3.6m

A pipenv clean does not raise the issue anymore.
So it may be a workaround to this isuse, at the moment, to force headers/static libraries installation.
