I can't reproduce with py_cui 0.1.6:

PS C:\Users\jwlodek> pip install py_cui
Collecting py_cui
  Using cached py_cui-0.1.6-py3-none-any.whl
Requirement already satisfied: windows-curses in c:\users\jwlodek\appdata\local\programs\python\python38\lib\site-packages (from py_cui) (2.2.0)
Installing collected packages: py-cui
Successfully installed py-cui-0.1.6

The 0.1.5 release has this problem - it was an oversight when I uploaded to PyPi, which is why 0.1.6 was released. It seems in your case pip is trying to install the cached 0.1.5 version. Could you try purging py_cui from the cache and installing fresh?

[livvy94]

I just ran pip cache purge and tried installing again, and it says this.

Am I clearing the cache correctly? It says Files removed: 4 when I run purge again.
