在Production中找不到文件’twitter / bootstrap’
我正在使用Twitter的Bootstrap翻译成SCSS文件。 它适用于本地开发，但是当我预编译并推送到Heroku（使用Cedar堆栈）时，我得到了这个：
> Started GET "/" for 74.57.16.130 at 2012-01-28 17:16:36 +0000 > Processing by StaticPagesController#home as HTML Rendered > static_pages/home.html.erb within layouts/application (0.7ms) > Completed 500 Internal Server Error in 4ms > > ActionView::Template::Error (couldn't find file 'twitter/bootstrap' > (in /app/app/assets/stylesheets/application.scss.css:11)): > 8: > 6: > 4: 我正在使用Rails 3.2.0，该应用程序正在使用Heroku，直到我添加了SASS文件。
你在用gem吗？ 确保您的gem不属于资产组，并且可以在生产中访问。
来自GemFile
# Gems used only for assets and not in production environments by default.
所以只需将gem移到任何一组之外，你应该没问题。
把它放在你的gemfile中
gem "twitter-bootstrap-rails", "~> 2.0rc0"
BootStrap 2.0中的CSS无效导致SCSS编译失败
您可以通过查看输出来validation这一点
git push heroku master
你应该看到一些错误：
-----> Preparing app for Rails asset pipeline Running: rake assets:precompile rake aborted! Invalid CSS after "...er-radius:0 \0/": expected expression (eg 1px, bold), was ";}" (in /tmp/build_1k8ugei34dpcw/app/assets/stylesheets/application.css) Tasks: TOP => assets:precompile:primary (See full trace by running task with --trace) Precompiling assets failed, enabling runtime asset compilation Injecting rails31_enable_runtime_asset_compilation Please see this article for troubleshooting help: http://devcenter.heroku.com/articles/rails31_heroku_cedar#troubleshooting
在config/environments/production.rb添加以下行：
config.assets.precompile = [/^[-_a-zA-Z0-9]*\..*/]
我的猜测是它没有添加你所有的资产。
这至少解决了heroku中的问题
只是降级到sass-rails 3.1.4
group :assets do gem 'coffee-rails', '~> 3.1.1' gem 'uglifier', '>= 1.0.3' gem 'sass-rails', '3.1.4' gem 'bootstrap-sass', '~> 2.0.2' end
当您将rails应用程序部署到heroku.com时，您会看到类似的内容
Precompiling assets failed, enabling runtime asset compilation ... could not connect to server: Connection refused Is the server running on host "127.0.0.1" and accepting TCP/IP connections on port xxxx?
只需将其添加到config / application.rb即可
config.assets.initialize_on_precompile = false
确保在config / environments / production.rb中，你有……
config.serve_static_assets = true
