我正在尝试部署一个基本的应用程序，但它无法正常工作.使用

I'm trying to deploy a basic app and it's not working. Using

我收到此错误消息:

bundle exec rake -P 似乎工作正常.

我的Gemfile中没有什么特别的，我刚刚添加了Bootstrap:

There's nothing special in my Gemfile, I just added Bootstrap:

source 'rubygems' # Bundle edge Rails instead: gem 'rails', github: 'rails/rails' gem 'rails', '4.2.5.1' # Use SCSS for stylesheets gem 'sass-rails', '~> 5.0' # Use Uglifier as compressor for JavaScript assets gem 'uglifier', '>= 1.3.0' # Use CoffeeScript for .coffee assets and views gem 'coffee-rails', '~> 4.1.0' # See github/rails/execjs#readme for more supported runtimes # gem 'therubyracer', platforms: :ruby # Use jquery as the JavaScript library gem 'jquery-rails' # Turbolinks makes following links in your web application faster.

Read more: github/rails/spring gem 'spring' end group :production do gem 'pg' gem 'rails_12factor' end ruby "2.2.3"

好吧，我不知道为什么会这样，因为我有另一个可以正常工作的项目.我检查了所有内容，仍然给了我该信息.

Well, I don't see why it's happening, since I have another project that is working normally. I checked everything and it still gives me that message.

推荐答案

有时Heroku在部署资产时引发了问题.您可以预编译资产并将其推送到Heroku.

Sometimes Heroku throws an issue on deployment about assets. You can precompile assets and push it to Heroku.

RAILS_ENV=production bundle exec rake assets:precompile

更新:

如果它不起作用，请确保添加 RAILS_SERVE_STATIC_FILES env.到您的服务器.

In case of it doesn't work, make sure to add RAILS_SERVE_STATIC_FILES env. to yr server.

将其设为enabled或true或anything:)
