!pip install nltk -> permission denied

问题

I'm trying to install nltk with the following notebook command:

!pip install nltk

However, that throws the following error:

error: could not create '/usr/local/src/bluemix_ipythonspark_141/notebook/lib/python2.7/site-packages/nltk': 
Permission denied

How can I install nltk from the Jupyter notebook? Note that the spark environments on bluemix can only be accessed via the notebook. There isn't she'll access to the environment.

回答1:

As the question is about IPython notebooks on Bluemix, the following suffices:

!pip install --user nltk

There is no need for manipulating sys.path.

回答2:

The solution was to install from the notebook as follows:

!pip install --user nltk

Then in the next cell enter:

import os
says.path.append(os.getenv('HOME')+'/.local/lib/python2.7/site-packages')
import nltk

Update: you shouldn't have to manipulate the sys.path as stated in the accepted answer.

I am not sure if the actual issue is a permission issue or something else. If you have sudo access, you can try running the above command with a sudo prefix to it and see if it fixes it.
