title: How can I fix pip install error: 'EnvironmentError: [Errno 42] Illegal byte sequence'?
body: <p>I am trying to download <code>kivy</code> module using <code>pip</code>.</p>
  
  <p>When I run the <code>pip install command</code>, I got an error: <code>Could not install packages due to an EnvironmentError: [Errno 42] Illegal byte sequence.</code></p>
  
  <p>I already re-installed <code>python</code>, I am running as an administrator and I also tried to download via the wheel file. All of the above causes the same environment error.</p>
