Requirement.parse ('sechs> = 1.6.0') Version über Python

Question

Wenn ich laufen diese Kommata:

sudo pip Notebook installieren

und dann ist dies der Fehler:

The directory '/Users/wangfei/Library/Caches/pip/http' or its parent directory is not owned by the current user and the cache has been disabled. Please check the permissions and owner of that directory. If executing pip with sudo, you may want sudo's -H flag.

Was soll ich tun, um dies zu beheben?

Answer 1

Sie haben six 1.4.1 installiert, aber das Modul erfordert 1.6 oder höher. Running sudo pip install --upgrade six sollte Ihr Problem beheben.
