title: pyspark: The system cannot find the path specified
body: <p>I just installed pyspark 2.2.0 using conda (using python v3.6 on windows 7 64bit, java v1.8)</p>
  
  <pre><code>$conda install pyspark
  </code></pre>
  
  <p>It downloaded and seemed to install correctly with no errors. Now when I run <code>pyspark</code> on the command line, it just tells me "The system cannot find the path specified."</p>
  
  <pre><code>$pyspark
  The system cannot find the path specified.
  The system cannot find the path specified.
  </code></pre>
  
  <p>I tried including the pyspark path directory in my PATH environment variables, but that still didn't seem to work, but maybe I am giving the wrong path? Can anyone please advise. Does the Java path need to be specified in PATH environment variables or something? Thanks</p>
