Impossibile installare virtualenvwrapper su OSX 10.11 El Capitan

Question

Recentemente ho cancellato il mio Mac e reinstallato OSX El Capitan beta pubblica 3. Ho installato pip con sudo easy_install pip e installato virtualenv con sudo pip install virtualenv e non ho avuto problemi.

Ora, quando cerco di sudo pip install virtualenvwrapper, ricevo il seguente:

Users-Air:~ User$ sudo pip install virtualenvwrapper 

The directory '/Users/User/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.

Poiché la questione sembra essere con il pacchetto six, cercando manualmente per disinstallarlo con sudo pip uninstall six risultati nella stesso errore. L'uscita suggerisce di usare il flag -H pure, ma ho ancora ottenere praticamente lo stesso errore:

devo radici disabile con sudo nvram boot-args="rootless=0", e questo ha avuto alcun effetto. Qualsiasi aiuto sarebbe apprezzato!

Answer 1

È possibile installare manualmente le dipendenze che non esistono su un supporto 10.11 di installazione, quindi installare gli altri pacchetti con --no-deps per ignorare le dipendenze. In questo modo salterà lo six (e lo argparse anch'esso già installato). Funziona sulla mia installazione 10.11 beta 6:

sudo pip install pbr 
sudo pip install --no-deps stevedore 
sudo pip install --no-deps virtualenvwrapper 

E nessuna necessità di disabilitare rootless.

Answer 2

sudo pip install virtualenvwrapper --ignore-installed six 

Funziona anche

Answer 3

Il comando ha funzionato con successo per me, ma quando vado a /Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages Ma virtualenvwrapper.sh non si trova. Credo che se virtualenvwrapper.sh non viene trovato, non possiamo eseguire virtual env. Qualche idea?
