Problem att installera "getkey package"

Jag försöker installera getkey till PyCharm. Men får felmeddelande. Jag fick först meddelande att pip inte var senaste uppdateringen. Efter detta kommer ett nytt felmeddelande. Som säger såhär:

Jag blir så frustrerad har ingen aning hur jag ska göra nu.

Nån som vet?

p.s

Någon annan bra IDE för python där jag kanske har större lycka att installera package?
