title: node-gyp failing every time because of bad build tools directory
body: <p>I've been struggling with this for several hours, and came with no solution.</p>
  
  <p>Basically, when I try to install a node module depending on <code>node-gyp</code>, it fails every time - because it knows about a non-existent python directory, which is pointing to my old user dir. </p>
  
  <p>I've changed my username, because node has had problems with it - because of <code>ł</code> character in it, which it can't recognize.
  So, it points to <code>C:\Users\Micha�\.windows-build-tools\python27\python.exe</code> but it should point somewhere else and <strong>I want to change that</strong>. I've already lurked through system variables, the PATH itself, but I have no clues.</p>
  
  <p>Any ideas how to change that damn directory and bring node-gyp back to life? My time is running up and my boss is not very happy about it.</p>
