title: How to fix `The system cannot find the path specified` error on Windows 10?
body: <p>I am using Windows 10.</p>
  <p>I keep encountering the error message <code>The system cannot find the path specified</code> whenever I run a python script, start a cygwin terminal, bash script ...</p>
  <p>There is no meaningful error message to pinpoint the exact cause. I suspect this is due to one of the pathnames in PATH variable to be pointing to non-existent path. How can I find out which pathname is causing it?</p>
