title: error: command 'cl.exe' failed: No such file or directory Python 3.4
body: <p>I've been trying to install pyodbc 3.0.7 by running python setup.py install but continue to have problems. Currently I've hit the "error: command 'cl.exe' failed: No such file or directory" wall. I've looked online for longer than I'd like to admit trying to figure out what is going on. </p>
  
  <p>I'm using a 64 bit version of Python 3.4</p>
  
  <p>I've got Microsoft Visual Studio 10.0. </p>
  
  <p>I've confirmed that vcvarsall.bat is in Program Files (x86)\Microsoft Visual Studio 10.0\VC. </p>
  
  <p>I am running 64 bit so I added the amd64 folder and put vcvars64.bat inside Program Files (x86)\Microsoft Visual Studio 10.0\VC\bin\amd64</p>
  
  <p>I confirmed cl.exe is in Program Files (x86)\Microsoft Visual Studio 10.0\VC\bin</p>
  
  <p>I've restarted my computer just to make sure that wasn't the problem. </p>
  
  <p>But when I trying installing pyodbc I get the following</p>

  <p>I've always used pip so this isn't something I'm familiar with so maybe I did something wrong. Any help and I'd be eternally grateful as I think I've exhausted all resources at this point. (Or a prebuilt copy of pyodbc 3.0.7 would also work!)</p>
