title: How to install urllib3[secure] without pip
body: <p>I have a old RHEL5 box running python 2.7 and I have to do a local install as the regular python site-packages are on a NFS filer I cannot write to.  I need to install urllib3 and according to this doc: <a href="https://urllib3.readthedocs.io/en/latest/user-guide.html#ssl-py2" rel="nofollow noreferrer">https://urllib3.readthedocs.io/en/latest/user-guide.html#ssl-py2</a> 
  I should execute:</p>
  
  <pre><code>pip install urllib3[secure]
  </code></pre>
  
  <p>But I cannot figure out how to get pip to install one of my local filesystems. I have done ...</p>
  
  <pre><code>python setup.py install --prefix=/apps/local_packages
  </code></pre>
  
  <p>But I do not know how to get the "secure" install using setup.py.</p>
  
  <pre><code>python setup.py install[secure] --prefix=/apps/local_packages
  </code></pre>
  
  <p>doesn't work.</p>
