I was attempting to deploy my Ruby on Rails app on Heroku when I faced below issue. (Of course, I've created and deployed on my local machine successfully.)
error Command "webpack" not found.
I don't have a clue about how to even know deploying any apps on heroku.
Of course I tried many ways and there was this error still now.
I referenced the posts that prevent precompiling of assets from here and here.
I followed all steps of above posts and it looked like to fix errors I faced. But I just spent my time. I've add this line config.assets.initialize_on_precompile = false into config/application.rb and saw this GitHub issue because I found this article from Google with error commands. But these was not helpful.
I write my error:
