title: How to install Numpy on Windows 8, in pyvenv?
body: <p>I have a virtual environment set up (Pyvenv, Python 3.4), but after executing activate.bat and the command <code>pip install numpy</code>, i get an error stating "Unable to find vcvarsall.bat".</p>
  
  <p>I added <code>C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC</code> to the PATH variable, which contains the vcvarsall.bat file, yet the error still remains. What is the issue here?</p>
