为什么我的rails资产管道中的js文件没有被编译？ [英] Why are js files in my rails asset pipeline not being compiled?
问题描述
我遇到类似这个问题的问题：
Rails资产管道不包括application.js清单中的必需文件然而，这个问题已经关闭，所以我重新询问它，但是我的具体情况。）
I am experiencing a problem similar to this question: Rails asset pipeline not including required files in application.js manifest However, that question was closed, so I am re-asking it, but with the specifics of my situation.)
Ruby 2.0.0，Rails 3.2.8，OSX 10.7.5，Chrome 28.0.1500.95

放在/ app / assets / javascripts中的文件似乎不是编译或出现在/ public / assets中
Files placed in "/app/assets/javascripts" do not appear to be compiling to or appearing in "/public/assets"
如果我放置一个文件，如app / assets / javascripts中的这个test.js文件：
If I place a file such as this test.js file in app/assets/javascripts:
alert("Hello!");
然后在我的应用程序中重新加载页面，此警报应该出现。 （我正在复制Ryan Bates在他的资产管道上的Railscast 大约在6:30进入视频）但是，没有出现警告。
and then reload a page in my app, this alert should appear. (I am replicating what Ryan Bates does in his Railscast on the Asset Pipeline at ~6:30 into the video) However, no alert appears.
一些测试我试着调试这个。
Some tests I did to try to debug this.
- （正如@Aidan下面推荐的那样）如果我rm -rf public / assets，那么
在我的布局中添加javascript_include_tag'test'，警告
出现。但是，也许是因为我是n00b，我不知道
如何帮助我调试问题。 - 如果我将// = require_test添加到app / javascripts / application.js到我的
清单文件，这会导致警报出现而不是 。
- (As recommended by @Aidan below) If I "rm -rf public/assets", then add "javascript_include_tag 'test'" to my layout, the alert does appear. However, maybe because I'm a n00b, I don't know how that helps me debug the problem.
- If I add //= require_test to app/javascripts/application.js to my manifest file, this does not result in the alert appearing.
// This is a manifest file that'll be compiled into application.js, which will include all the files
// listed below.
//
// Any JavaScript/Coffee file within this directory, lib/assets/javascripts, vendor/assets/javascripts,
// or vendor/assets/javascripts of plugins, if any, can be referenced here using a relative path.

// It's not advisable to add code directly here, but if you do, it'll appear at the bottom of the

我不应该看到test.js文件在这里？
有关问题可能是什么的任何建议？我可以提供任何其他信息来帮助调试此问题è？感谢您的帮助！

推荐答案
问题似乎与我的rails / gem版本有关。在从Rails 3.2.8更新到Rails 3.2.14（还需要将机架gem从1.4.1更新到1.4.5）后，问题得到了解决，资产/ javascripts中的项目现在正在编译/添加到公共/资产中。请注意，我创建了一个全新的gemset作为其中的一部分，因此该问题可能与Rails版本无关，只是一个需要重新创建的损坏宝石集的问题。
The problem appears to have been related to my rails/gem versions. After updating from Rails 3.2.8 to Rails 3.2.14 (which also required updating the rack gem from 1.4.1 to 1.4.5) the issue was resolved and items in assets/javascripts are now being compiled/added to public/assets. Note that I created a completely new gemset as part doing this, so the issue may have had nothing to do with the Rails version and simply was a questions of a "corrupted" gem set that needed to be re-created.
