How to install webpacker inside rails Engine?

Question

I have built one Rails Engine using rails 6.0.3.2 as by default webpacker is not present inside the engine so I have configured the webpacker manually using https://github.com/rails/webpacker/blob/master/docs/engines.md link. But when I am trying to do rails app:webpacker:compile the error is

Compilation failed: yarn run v1.19.1 info Visit https://yarnpkg.com/en/docs/cli/run for documentation about this command.

error Command "webpack" not found. How can I configure Webpacker inside my rails engine?

Unfortunately, this is something the rails community has been struggling with for several years now. github.com/rails/webpacker/issues/348 – Logic
