How to remove Yarn from a Rails app completely?

问题:

I'm building a Rails 5.1.x rails app with jQuery and a few other libraries. Rails is insisting on having Yarn on, which is fine on development machine but I cannot have it on production.

Is there a way to not have rails use Yarn by default? Remove yarn.lock and node_modules and everything else that comes with it.

回答1:

When you create a rails project, you can add --skip-yarn as rails new app_path --skip-yarn.

回答2:

Remove the following lines from the files

bin/setup.rb and bin/update.rb

-  # Install JavaScript dependencies if using Yarn
-  system('bin/yarn')

config/initializers/assets.rb

# Add Yarn node_modules folder to the asset load path.
Rails.application.config.assets.paths << Rails.root.join('node_modules')
