ruby-on-rails - Heroku css 在 Assets :precompile 之后未加载

Question

Heroku 突然停止工作并给了我这个错误:

  could not connect to server: Connection refused
  Is the server running on host "127.0.0.1" and accepting
  Precompiling assets failed.

经过一番研究后，我运行了这一行:

 running RAILS_ENV=production bundle exec rake assets:precompile

这有效，但现在当我将更新推送到heroku时，新的CSS不会加载。此行以前从未显示过:

Running: bundle install --without development:test --path vendor/bundle --binstubs vendor/bundle/bin --deployment

如果可能的话，您能否解释一下为什么 asset:precompile 行解决了我原来的问题？

Answer 1

运行此命令:

 bundle exec rake tmp:clear

 bundle exec rake assets:clean RAILS_ENV=production

 bundle exec rake assets:precompile RAILS_ENV=production

希望这有帮助!
