Es fällt mir schwer, mit pip fast alles zu installieren. Ich bin neu in der Codierung, daher dachte ich, dass dies möglicherweise etwas ist, was ich falsch gemacht habe, und habe mich für easy_install entschieden, um das meiste, was ich tun musste, zu erledigen, was im Allgemeinen funktioniert hat. Jetzt versuche ich jedoch, die nltk-Bibliothek herunterzuladen, und keiner erledigt den Job.
Ich versuchte einzutreten
sudo pip install nltk
habe aber folgende Antwort bekommen:

--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 Feedback freuen, wie ich Pip zum Laufen bringen kann oder wie ich das Problem in der Zwischenzeit umgehen kann.
