资产管道出现问题

Question

好了，我的资产管道突然开始在我的开发机器上出现问题。以前有效的JS函数现在抛出"not a function“错误。我知道我一定是做错了什么。一分钟前datatables jquery函数工作，然后抛出一个错误，然后它工作，现在它不工作或抛出错误。

这是我的application.js

//= require jquery
//= require jquery-ui
//= require jquery_ujs
//= require_self
//= require_tree .
//= require dataTables/jquery.dataTables
//= require dataTables/jquery.dataTables.bootstrap
//= require bootstrap
//= require bootstrap-tooltip
//= require bootstrap-popover
//= require bootstrap-tab
//= require bootstrap-modal
//= require bootstrap-alert
//= require bootstrap-dropdown
//= require jquery.ui.addresspicker
//= require raty
//= require jquery.alphanumeric
//= require jquery.formrestrict
//= require select2
//= require chosen/chosen.jquery
//= require highcharts
//= require jquery.lazyload

下面是我的一些布局标题：

  <%= stylesheet_link_tag "application", media: "all" %>
  <%= yield(:scripthead) %>
  <%= javascript_include_tag "application" %>
  <%= csrf_meta_tags %>    
  <%= yield(:head) %>   

上面我使用load从google加载在线脚本，因为它们只在一些页面上需要，如果包含在应用程序布局中，通常会减慢网站的速度。我试着删除were，但仍然有问题，即使在清除了浏览器缓存并运行了rake assets:clean (只是为了安全起见)。

下面是CSS和元标记之间显示的内容(对于一个在yield中没有任何内容的页面)：

来自application.rb：

config.assets.initialize_on_precompile = false
# Enable the asset pipeline
config.assets.enabled = true
config.action_controller.assets_dir = "#{File.dirname(File.dirname(__FILE__))}/public"

# Version of your assets, change this if you want to expire all your assets
config.assets.version = '1.0'

很抱歉，我不确定还能包括什么来帮助解决这个难题，但任何建议都将不胜感激。在我尝试上传到heroku之前，我没有遇到任何问题，但现在一切都乱套了。

编辑：

在控制台上，我看到了

Uncaught TypeError: Cannot read property 'Constructor' of undefined bootstrap-popover.js:33
Uncaught ReferenceError: google is not defined jquery.ui.addresspicker.js:25
Uncaught TypeError: Object [object Object] has no method 'popover' overall:476

编辑2：

多亏了下面的一个评论，我才能弄明白这一点。我不得不重新调整application.js包含的内容以使其更有意义：

//= require jquery
//= require jquery-ui
//= require jquery_ujs
//= require bootstrap
//= require bootstrap-tooltip
//= require bootstrap-popover
//= require bootstrap-tab
//= require bootstrap-modal
//= require bootstrap-alert
//= require bootstrap-dropdown
//= require dataTables/jquery.dataTables
//= require dataTables/jquery.dataTables.bootstrap
//= require jquery.ui.addresspicker
//= require raty
//= require jquery.alphanumeric
//= require jquery.formrestrict
//= require select2
//= require chosen/chosen.jquery
//= require highcharts
//= require jquery.lazyload
//= require_self
//= require_tree .

天哪，这快把我逼疯了..不，它还是不能工作。最后一次编辑让一切正常工作，但随后我运行了rake assets:再次预编译并推送到heroku。它在Heroku上又不起作用了..信不信由你，当我回到我的本地主机版本时，它又坏了，现在又抛出了不同的错误，并且再次没有加载数据表！

Uncaught ReferenceError: google is not defined jquery.ui.addresspicker.js:25
Uncaught ReferenceError: google is not defined application.js:26
Uncaught TypeError: Object [object Object] has no method 'lazyload' overall:496

Answer 1

你确定你没有把分号忘在JS里的什么地方吗？asset管道不执行任何代码清理...

在浏览器的JS控制台中查看错误发生的位置……

编辑:好的，我想看看是怎么回事。尝试取出末尾的require_tree，并手动加载您尚未显式说明的任何其他JS文件。最终发生的是，require_tree覆盖了以前明确列出的任何要求，并最终按字母顺序加载它们。

此外，我不知道您在bootstrap.js中使用的是什么gem (或者您是否正在使用它)，但也可以尝试使用twitter/bootstrap，而不只是bootstrap

Answer 2

这是在什么环境下发生的？尝试在env/production.rb或您正在运行的任何环境中执行config.assets.enabled = true。我相信在生产环境中这个设置是默认关闭的。
