title: Django installation issue
body: <p>I've just begun learning Django.
  I ran the following command to install Django:</p>
  
  <pre><code>1. download and unpack Django-2.1.5.tar.gz in /u01
  2. cd /u01/Python-3.7.2/bin
  3. ./python3 -m venv ./python3 -m venv /u01/django  
  4. source /u01/django/bin/activate
  5. cd /u01/django/bin
  6. ./pip3 install -e /u01/Django-2.1.5  
  Obtaining file:///u01/Django-2.1.5
  Collecting pytz (from Django==2.1.5)
    Retrying (Retry(total=4, connect=None, read=None, redirect=None, status=None)) after connection broken by 'ConnectTimeoutError(&lt;pip._vendor.urllib3.connection.VerifiedHTTPSConnection object at 0x7fe464ed25c0&gt;, 'Connection to pypi.org timed out. (connect timeout=15)')': /simple/pytz/

  <p>So I downloaded and installed the latest pytz-2018.9:</p>
  
  <pre><code>$ cd /u01/Python-3.7.2/bin
  $  ./pip3 install ../../pytz-2018.9
  Processing /home/alelai/pytz-2018.9
  Installing collected packages: pytz
    Running setup.py install for pytz ... done
  Successfully installed pytz-2018.9
  </code></pre>
  
  <p>and reran step 2-6 above. the same error occured.</p>
