Import Fehler nach 16.04 LTS pip packagaes mit sudo

Question

Auf Ubunutu installieren, bei dem Versuch, Pakete insatll pip install mit erhalte ich die Fehlermeldung:

Traceback (most recent call last): 
    File "/usr/local/lib/python3.5/dist-packages/pip/basecommand.py", line 215, in main 
    status = self.run(options, args)

    prefix=options.prefix_path,

    mkdir(name, mode) 
PermissionError: [Errno 13] Permission denied: '/usr/local/lib/python3.5/dist-packages/graphviz-0.5.2.dist-info' 

so entschied ich mich sudo pip install stattdessen zu verwenden, die gut funktioniert, bis ich versuchte, wobei die Verpackung zu meinem Django-Projekt importieren, ich die folgenden Import Fehler:

ImportError: No module named 'graphviz' 

wie kann ich diese Pakete importieren, ohne die Importfehler zu begegnen? oder wie kann ich sie ohne sudo und ohne Erlaubnisfehler installieren?

Answer 1

Verwenden Sie eine virtuelle Umgebung? Sie sollten für jedes einzelne Projekt immer separate virtuelle Umgebungen haben.

Installieren Sie alles in Ihrem Hauptverzeichnis wird ein Chaos zu schaffen.

Installieren virtuellen Umgebung, Dokumente finden Sie hier:

https://virtualenv.pypa.io/en/stable/

Erstellen Sie Ihre env mit dem Befehl:

virtualenv -p python3.5 env

aktivieren sie env (sagen Konsole gegeben env verwenden):

source env/bin/activate

und dann können Sie Ihre Pakete mit einfachen pip install package_name

Answer 2

Das ist für mich gearbeitet installieren in Ubuntu 16.04:

sudo apt-get -y install python-pip 
curl "https://bootstrap.pypa.io/get-pip.py" -o "get-pip.py" 
python get-pip.py 

Um die Version zu überprüfen und überprüfen Sie die Installation:

pip -V
