title: Trying to install a package using pip but getting this error "the filename, directory name, or volume label syntax is incorrect"
body: <p>In the command window I ran this:</p>
  
  <pre><code>python -mpip --trusted-host pypi.org --trusted-host files.pythonhosted.org install django
  </code></pre>
  
  <p>But getting the error. It looks like some problem with my environment settings, but I've checked them and they look fine. Anyone seen this issue before?</p>
