title: Cant pip install from freeze
body: <p>I have just installed a bunch of packages to use MySQL on python, but I'm not sure which one did the trick (whichever it was,  only worked after a reboot).</p>
  
  <p>Now I'm trying to use it on a virtualenv, so I created a requirements.txt with pip freeze on my local machine, then, I created a virtualenv and tried <code>pip install -r requirements.txt</code>. However, can't install any of the packages, and the error is:</p>
  
  <pre><code>Could not find a version that satisfies the requirement mysql-connector-python&lt;=2.0.4 (from -r myvi/requirements.txt (line 1)) (from versions: )
  No matching distribution found for mysql-connector-python&lt;=2.0.4 (from -r myvi/requirements.txt (line 1))
  </code></pre>
  
  <p>Tried editing the file manually, but whatever the first line is, always report the same error.</p>
  
  <p>Googling the subject, I've only found solutions that are particular to the packages, but I get errors for regardless of the package. Why is this happening? </p>
  
  <p>EDIT: I thought that all the packages were raising error, but only some of them are. Namely:</p>
  
  <pre><code>adium-theme-ubuntu==0.3.4
  mysql-connector-python==2.0.4
  Pyste==0.9.10
  unity-lens-photos==1.0
  </code></pre>
  
  <p>I thought that if it was built by <code>pip freeze</code> , it would be possible to <code>pip install</code> it.</p>
