If you see something like this when you do
ERROR in ./app/app.js Module build failed: Error: Couldn't find preset "es2015" relative to directory "/home/yourname"
That’s becuase you have a
.babelrc in your home directory but not in your project directory. To get rid of this error, either deleting the
.babelrc in your home directory or creating one in your current project diretory.
