pipenv - 'pew' is not recognized as an internal or external command, operable program or batch file

Why can't I enter the pipenv shell?

PS C:\Users\...\desktop\projects\myproject> pip freeze
backports.shutil-get-terminal-size==1.0.0
certifi==2018.1.18
chardet==3.0.4

So pew is definitely installed.

PS C:\Users\...\desktop\projects\myproject> pipenv shell
Creating a virtualenv for this project…
New python executable in C:\Users\...\.virtualenvs\myproject-bRnmVZJC\Scripts\python.exe
Installing setuptools, pip, wheel...done.

Virtualenv location:
'pew' is not recognized as an internal or external command,
operable program or batch file.

But somehow not when I enter the pipenv shell (so that I can install packages that weren't installed with pipenv)

Solution

The problem was that I had installed pipenv using Python 2.7

To fix, I installed both Python 2.7 and 3.4 and set paths for both so that python2 runs 2.7 and python3 runs 3.4.

Then I installed pipenv using python3, and initiated a pipenv running in python 2.7.

python3 -m pip install --user pipenv
cd C:\Users\...\desktop\projects\myproject>

then I set my user base's binary directory to my PATH and added

C:\Users\Username\AppData\Roaming\Python36\Scripts

to my PATH, then

pipenv --two install
pipenv shell

and voilà!
