通过 twitter-bootstrap-rails gem 升级到 bootstrap 2.0.1 后 Heroku 部署失败

Question

更新：

在 git push heroku master 期间显示此错误：

-----> Preparing app for Rails asset pipeline
       Running: rake assets:precompile
       rake aborted!
       couldn't find file 'twitter/bootstrap'
       (in /tmp/build_2pmsvze33th3e/app/assets/javascripts/application.js:9)

       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

我按照此 指南。之后，我在部署到 Heroku 时遇到此错误：

以前我有一个现有的 Rails 3.1.3 应用程序已经在 Heroku Cedar 上使用 Bootstrap 2 布局。

有什么想法吗？

Answer 1

删除以下文件 app/assets/stylesheets/bootstrap.css.less 并享受。

Answer 2

我还将 gem“twitter-bootstrap-rails”移到资产组之外，这很有效！

Answer 3

我只需将 gem“twitter-bootstrap-rails”移出 :assets 块并将其放在 gemfile 的顶部即可解决此问题。

Answer 4

解决了。

只需在 Gemfile 中注释掉以下行：

#gem 'twitter-bootstrap-rails', :git => 'http://github.com/seyhunak/twitter-bootstrap-rails.git'

并使用 gem "twitter-bootstrap-rails", "~> 2.0.1.0" 然后运行 ​​bundle update

即可完成，我之前失败的分支是：

-  revision: a5d67d23afeaa76eb52c6f87d55ff407f9c753f2
-    twitter-bootstrap-rails (2.0.1)

Answer 5

对我来说，解决方案是删除 application.css

*= require twitter/bootstrap

Answer 6

运行时资产编译期间出现错误的另一个解决方法是使用 asset_sync gem。
