• I am on the latest Poetry version.
• I have searched the issues of this repo and believe that this is not a duplicate.
• If an exception occurs when executing a command, I executed it again in debug mode (-vvv option).

• OS version and name: windows7
• Poetry version: 1.1.4
• Python version: 3.7.8

Issue

I cannot run even poetry --version now.

Traceback (most recent call last):
File "C:\Users\Administrator.poetry\bin\poetry", line 12, in
from poetry.console import main
File "C:\Users\Administrator.poetry\lib\poetry\console_init_.py", line 1, in

ModuleNotFoundError: No module named 'cleo'
