Have you run ./bin/rails webpacker:install?

[theredorm]

@gauravtiwari yep

[theredorm]

@gauravtiwari, I got this error. Can not find application.js in /home/andrew/railsapp/wpacktest/public/packs/manifest.json. Is webpack still compiling? And after I looked in Troubleshooting and executed the command ./bin/webpack-dev-server

[gauravtiwari]

You get that error because webpack isn't installed. Could you run this ./bin/rails webpacker:install again please and follow the options?

[gauravtiwari]

Btw, what version of webpacker you using? It's 1.1

Got same error. Decided this way:

• Update nodejs to 6.x (I had 5.x).
• Run ./bin/rails webpacker:install and ./bin/yarn install.
• Run bin/webpack-dev-server.
• If there will be errors about missing webpack or babel-loader - add them to package.json:

{
  "devDependencies": {
    "webpack-dev-server": "^2.4.2"
  },
  "dependencies": {
    // another dependencies
    "babel-core": "^6.24.0",
    "babel-loader": "^6.4.1",
    "webpack": "^2.3.2",
  }
}

• Run ./bin/yarn install and bin/webpack-dev-server again.

Check the prerequisites of webpacker 1.1 https://github.com/rails/webpacker#prerequisites

[dhh]

Would be nice if we could programmatically check these prerequisites and give the right error message on what to do.
