Switching to the <code>brew</code> installed python fixed the issue.

And here it is with <code>nltk</code> resolving now:

The path you try to install the package is <code>/usr/local/lib/python2.7/site-packages</code>, so I suppose <code>pip</code> works for the Python which is installed by <code>brew</code>, but the project interpreter is the system Python.

So maybe you should use <code>/usr/local/Cellar/python/2.7.13/bin/python</code> path.

You can run this to check out the Python version and pip version that you're using:

<pre><code> ~ which python
/usr/local/bin/python
 ~ ls -al /usr/local/bin/python
lrwxr-xr-x 1 ** ** /usr/local/bin/python@ -&gt; ../Cellar/python/2.7.13/bin/python

 ~ which pip
/usr/local/bin/pip
 ~ ls -al /usr/local/bin/pip
lrwxr-xr-x 1 ** ** /usr/local/bin/pip@ -&gt; ../Cellar/python/2.7.13/bin/pip
</code></pre>

I suggest Mac OS users install another Python and do not use the system version, this will protect your system Python tasks. Also another idea is to use <a href="https://virtualenv.pypa.io/en/stable/" rel="nofollow noreferrer">virtualenv</a> which is a tool to create isolated Python environments.

Hope this helps.

Also add your site-packages path in in your project classpath if you still get import error

e.g. <code>/usr/local/lib/python2.7/site-packages</code>

I have installed the <code>nltk</code> package via <code>sudo pip install nltk</code> and it works fine:

<pre><code>21:07:00/~ $python -c "import nltk"
</code></pre>

Just to be sure there were no clashing with <code>brew</code> pip I also did:

<pre><code>21:06:24/~ $python -m pip install nltk
Requirement already satisfied: nltk in /usr/local/lib/python2.7/site-packages
Requirement already satisfied: six in /usr/local/lib/python2.7/site-packages (from nltk)
</code></pre>

So both brew and system python are happy together.

Intellij is another story. The basic python is working but the pip installed libraries are MIA:

Here are the relevant SDK settings:

Module level:

Project level:

So what is needed in this project to have pip libraries welcomed?
