Es fällt mir schwer, mit pip fast alles zu installieren. Ich bin neu in der Programmierung, daher dachte ich, dass dies möglicherweise etwas ist, was ich falsch gemacht habe, und habe easy_install deaktiviert, um das meiste von dem zu bekommen, was ich getan habe, was im Allgemeinen funktioniert hat. Jetzt versuche ich jedoch, die nltk-Bibliothek herunterzuladen, und beides erledigt den Job nicht.

Ich versuchte einzutreten

sudo pip install nltk

bekam aber folgende antwort:

--easy_install installed fragments of the library and the code ran into trouble very quickly upon trying to run it.

Irgendwelche Gedanken zu diesem Thema? Ich würde mich sehr über ein Feedback darüber freuen, wie ich in der Zwischenzeit entweder Pip zum Laufen bringen kann oder etwas, um das Problem zu umgehen.
