How do I precompile assets in rails in development environment?

问题

I want to manually precompile some assets in my dev environment (to check the content of the compiled js and css files) from the command line.

I am running

RAILS_ENV=development bundle exec rake assets:precompile

but my js and css are not compiled in the public/assets folder, only the images are. Any idea why that may be happening?

回答1:

Try adding this to your config/environments/production.rb :

config.assets.precompile += %w( *.css *.js )
