Module build failed: Error: spawn bin/rails ENOENT

After adding the ERB loader and adding the .erb file extension to my application pack (with webpacker), I am getting the following error:

ERROR in ./app/webpack/packs/application.js.erb
Module build failed: Error: spawn bin/rails ENOENT
    at _errnoException (util.js:1024:11)

 @ multi (webpack)-dev-server/client?http://localhost:3035 ./app/webpack/packs/application.js.erb

it is also happening with the sample hello_erb.js.erb pack.

Here is an example app that reproduces the problem: https://github.com/jonhue/test_app

Solution

  • The ERB runner configuration contains a setting that must be changed for it to work on Windows. Open config\webpack\loaders\erb.js and replace this line:

    runner: "bin/rails runner"

    with this line:

    runner: "ruby bin\\rails runner
