title: Upgrading to pip version 9.0.1
body: <p>I am getting the following error message when installing some libraries on PyCharm: </p>
  
  <blockquote>
    <p>Command "python setup.py egg_info" failed with error code 1 in
    C:\Users\user.name\AppData\Local\Temp\pycharm-packaging\hachoir-metadata\
    You are using pip version 8.1.1, however version 9.0.1 is available.
    You should consider upgrading via the 'python -m pip install --upgrade
    pip' command.</p>
  </blockquote>
  
  <p>Path to pip3.5.exe: </p>
  
  <pre><code>C:\Users\user.name&gt;AppData\Local\Programs\Python\Python35-32\Scripts\pip3.5.exe
  </code></pre>
  
  <p>I have run the following from cmd:</p>
  
  <pre><code>C:\Users\user.name&gt;AppData\Local\Programs\Python\Python35-32\Scripts\pip3.5.exe install upgrade pip
  </code></pre>
  
  <p>Which gives me the following: </p>
  
  <blockquote>
    <p>Could not find a version that satisfies the requirement upgrade (from
    versions: ) No matching distribution found for upgrade You are using
    pip version 8.1.1, however version 9.0.1 is available. You should
    consider upgrading via the 'python -m pip install --upgrade pip'
    command.</p>
  </blockquote>
  
  <p>I then tried both: </p>
  
  <pre><code>C:\Users\user.name&gt;AppData\Local\Programs\Python\Python35-32\Scripts\pip.exe pip install upgrade pip
  </code></pre>
  
  <p>and:</p>
  
  <pre><code>C:\Users\user.name&gt;AppData\Local\Programs\Python\Python35-32\Scripts\pip.exe python -m pip install --upgrade pip
  </code></pre>
  
  <p>From pip.exe (rather than pip3.5exe as they didn't work on that) which resulted in: </p>
  
  <blockquote>
    <p>ERROR: unknown command</p>
  </blockquote>
  
  <p>I am pretty sure that I am doing something wrong here, but not quite sure what?</p>
  
  <p>Tried the following:<br>
  C:\Users\user.name>\AppData\Local\Programs-m pip install --upgrade pip</p>
  
  <pre><code>C:\Users\user.name&gt;\AppData\Local\Programs\Python\Python35-32\Scripts\pip.exe -m pip install --upgrade pip
  C:\Users\user.name&gt;\AppData\Local\Programs\Python -m pip install --upgrade pip
  </code></pre>
