Ho difficoltà a usare pip per installare quasi tutto. Sono nuovo nella programmazione, quindi ho pensato che forse questo è qualcosa che ho sbagliato e ho scelto easy_install per ottenere la maggior parte di ciò di cui avevo bisogno, che generalmente ha funzionato. Tuttavia, ora sto cercando di scaricare la libreria nltk e nessuno dei due sta portando a termine il lavoro.
Ho provato ad entrare
sudo pip install nltk
ma ha ottenuto la seguente risposta:

--easy_install installed fragments of the library and the code ran into trouble very quickly upon trying to run it.
Qualche idea su questo problema? Apprezzerei davvero un feedback su come posso far funzionare pip o qualcosa per aggirare il problema nel frattempo.
