title: Can't use installed pip package from git
body: <p>I'm working on Ubuntu 20.04 and I want to install a package from some repo in python.</p>
  <p><code>pip3 install git+https://path-to-repo.git</code></p>
  <p>this should have worked fine because when I do <code>pip3 show package_name</code> the package is found. However:</p>
  <pre><code>&gt; python3
  Python 3.8.2 (default, Mar 13 2020, 10:14:16) 
  [GCC 9.3.0] on linux
  Type &quot;help&quot;, &quot;copyright&quot;, &quot;credits&quot; or &quot;license&quot; for more information.
  &gt;&gt;&gt; import package_name
  Traceback (most recent call last):
    File &quot;&lt;stdin&gt;&quot;, line 1, in &lt;module&gt;
  ModuleNotFoundError: No module named 'package_name'
  </code></pre>
  <p>What am I doing wrong? How can I use the installed package?</p>
