title: webpack --watch exits after building once
body: <p>I was using <code>webpack --watch</code> statement to run my webpack in watch mode for building my ReactJS app. However for some reason, it stopped working now. It now just compiles the code once and terminates</p>
  
  <p>I tried the methods suggested in this SO post: <a href="https://stackoverflow.com/questions/26708205/webpack-watch-isnt-compiling-changed-files">webpack --watch isn&#39;t compiling changed files</a></p>
  
  <p>However it did not solve the problem for me. 
  Any help is appreaciated </p>
