title: "executable not specified" error when running python script
body: <p>I moved a script I was working on to another computer with the same version of python. When I try running the script on the second computer, I get an error that reads</p>
  
  <pre><code>error running myscript: Executable is not specified
  </code></pre>
  
  <p>Tried looking it up, didnt' seem to find anything.</p>
  
  <p>Is it possible this is because I installed python alone on the first computer, but anaconda on the second? I'm not really sure what could cause the error. As far as I can tell it has nothing to do with the code. Tested on the original computer and worked fine.</p>
