pip installa richieste di eccezioni e pip installa beautifulsoup4 exception

Question

Ho installato Python 3.4.1 su Windows 7, pip incluso e durante l'installazione ho selezionato l'aggiunta di python.exe a PATH.

Quando si esegue pip installare le richieste che ricevo:

C:\Python34>pip install requests

4\lib\site-packages

Mi chiedo che cosa significano queste eccezioni?

I pacchetti sono stati installati correttamente come indicato nel registro e funzioneranno correttamente oppure sto facendo qualcosa di sbagliato.

Perché le eccezioni e come si eliminano?

Answer 1

Tutte le eccezioni di autorizzazione indicano che il prompt dei comandi non ha diritti di amministratore.

Eseguire il prompt dei comandi come amministratore (cercare cmd nel menu di avvio, fare clic con il pulsante destro del mouse, Esegui come amministratore). Se ciò non funziona, prova a reinstallare pip; le autorizzazioni sui file potrebbero essere state rovinate in qualche modo.
