Are you actually installing anything with pipenv, your error message shows that you didn't. I get a similar error message when I do not tell pipenv to install something. — v0rtex, Nov 24 '18 at 03:52

I've met same problem and was lurking internet for a solution but having not much time and figured out some possible workaround for making it

I was tryin to install PIPEnvironment through Pycharm interpreter settings and problem occured:

Failed creating virtual environment

    line = line.decode(encoding)
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xcf in position 280: invalid continuation byte

I went to a file

"C:\Users\ogmamedo\AppData\Roaming\Python\Python37\site-packages\virtualenv.py"

And changed code like this:

encoding = sys.getdefaultencoding()
fs_encoding = 'OEM' #sys.getfilesystemencoding()

This helped me to pass that stage (first 10 seconds) when bug was occuring.

Why it's 'OEM'? Because as we see in that file - there are a call to a system prompt (cmd shell), and my system's cmd shell has encoding 'OEM'.

I'll point that this is a workaround, not a proper solution, but due to a lack of time and interest figuring out which of sides this bug belongs to (pycharm or pipenv) I wont continue to a proper solution.

use pipenv -h, UnicodeDecodeError: 'utf-8'
