启用JavaScript的测试出错（Bootstrap 3，Rails 4，Travis CI）
我有奇怪的错误，只出现在CI环境中。此错误不会出现在开发，生产甚至本地测试环境中。
I have strange error that appears only in CI environment. This error does not appear in develpment, production or even local test environments.
ActionController::RoutingError: No route matches [GET] "/fonts/bootstrap/glyphicons-halflings-regular.svg"
可以找到完整的跟踪这里
在开发和生产环境成功需要转到 /assets/bootstrap/glyphicons-halflings-regular.woff 。 / fonts / - / assets 和 svg $ c $有区别c> - woff 部分。启用JavaScript的所有错误都启用了测试（Poltergeist / PhantomJS驱动程序）。定期的Capybara测试都是绿色的。 Chrome devtools表示，字体文件的请求是由jquery.js生成的，而不是页面或css文件。
In development and production enviroments successfull reqest goes to /assets/bootstrap/glyphicons-halflings-regular.woff. There is a difference in /fonts/ - /assets and svg - woff part. All errors generated by JavaScript enabled tests (Poltergeist / PhantomJS driver). Regular Capybara tests are all green. Chrome devtools says that request for font file is generated by jquery.js, not the page or css file.
这是相关的到 bootstrap-sass gem。我正在使用它的版本3.3.4.1和Rails 4.2。
This is related to the bootstrap-sass gem. I'm using version 3.3.4.1 of it with Rails 4.2.
我提出的问题非常相似但略有不同：CI中的相同错误与 /fonts/bootstrap/glyphicons-halflings-regular.woff 但是dev中的路径不同， / fonts / glyphicons ... 。
My presenting issue was very similar but slightly different: the same error in CI with 404 for /fonts/bootstrap/glyphicons-halflings-regular.woff but a different path in dev, /fonts/glyphicons....
对我有用的解决方案是在包含带SASS的bootstrap JS之前添加以下行：
The solution that worked for me was adding the following line before including the bootstrap JS with SASS:
$icon-font-path: "bootstrap/";
@import 'bootstrap';
我最好的线索来自于gem的追踪者对此问题的评论：

My best clue came from the comments on this issue in the gem's tracker: https://github.com/twbs/bootstrap-sass/issues/480#issuecomment-49237119
