Rails Webpacker compile error on Production enviorment

ruby-on-rails webpack webpacker

I have the same issue when I run pre-built rails 6 app.Found out it is because of Webpack version inconsistency in yarn.lock file. Then when I run

yarn add @rails/webpacker

bundle update webpacker

as found in this comment , issue's solved.

ruby-on-rails webpack webpacker

Remove Webpacker:

rm -rf bin/webpack*

Install Webpacker:

rails webpacker:install

Compile by Webpacker in production mode:

RAILS_ENV=production rails webpacker:compile

ruby-on-rails webpack webpacker

I'd the same problem. Just run in development environment:

rails webpacker:install

If you use Docker, run:

docker exec rails-app-name rails webpacker:install
