body: <p>I am having troublings enabling nbextensions. I successfully installed it by typing</p>
  <pre><code>pip install jupyter_contrib_nbextensions
  </code></pre>
  <p>I then relaunched anaconda and ran in my notebook:</p>
  <pre><code>jupyter contrib nbextension install --user
  </code></pre>
  <p>However, it threw me an error:</p>
  <pre><code>File &quot;&lt;ipython-input-1-1c0e089b301b&gt;&quot;, line 1

                    ^
  SyntaxError: invalid syntax
