title: Jupyter Notebook not opening because of weird error
body: <p>When I try to open jupyter notebook the result is:</p>
  
  <blockquote>
    <p>Fata error in launcher: Failed to open executable</p>
  </blockquote>
  
  <p>I tried to google it yet nothing has matched my error. I don't know what to do any more. I've tried reinstalling Python so many times and I still get this result. My Python is version 3.8.1 by the way.</p>
