Webpacker can't find hello_react.js in /Users/khalidhosein/Desktop/myEPKmedia/builder/khalid101/public/packs/manifest.json. Possible causes:
1. You want to set webpacker.yml value of compile to true for your environment
unless you are using the `webpack -w` or the webpack-dev-server.
2. webpack has not yet re-run to reflect updates.
3. You have misconfigured Webpacker's config/webpacker.yml file.
4. Your webpack configuration is not creating a manifest.
Your manifest contains:
{
"application.js": "/packs/application-68dcba18197451fbb79e.js",
"application.js.map": "/packs/application-68dcba18197451fbb79e.js.map"
