title: Dist folder is not created after building vue js project
body: <p>I tried to run the npm run build command on my vue project. It is successfully running but no dist folder is created. I want to build this project and run it on the server. I am currently working on Windows OS.
  I tried to compare it with other project's webpack file but found no difference.</p>
