pipenv graph fails: No module named 'pipenv'

Issue description

With the newest version of pipenv (2018.10.9), pipenv graph fails with the error message ModuleNotFoundError: No module named 'pipenv'

Expected result

I expected pipenv graph to output the dependency graph of the venv.

Actual result

$ pipenv graph

ERROR:  Traceback (most recent call last):
  File "c:\\python27\\lib\\site-packages\\pipenv\\vendor\\pipdeptree.py", line 16, in <module>
    from pipenv.vendor.pip_shims import get_installed_distributions, FrozenRequirement
ModuleNotFoundError: No module named 'pipenv'

Steps to replicate

• Install version 2018.10.9 of pipenv.
• Run pipenv graph

Why this issue is closed? pipenv still facing the same problem

[wjv]

It appears that pipenv has transitioned from calling certain functions that are part of the pip API directory, to calling them via a shim which is installed as a submodule of pipenv.

I’m assuming that certain aspects of pipenv’s functionality are actually run inside the project virtualenv, and that this includes pipenv graph.

The problem is that, whereas pip generally is installed in the project virtualenv, pipenv isn’t, and hence these imports fail. If you do a pipenv run python and try to do the import, it’ll fail.

A (nasty, temporary?) workaround is to install pipenv into the project virtualenv (i.e. pipenv install pipenv).
