Javascript gem'内的配置；他的资产不起作用

我创建了一个名为gem的程序，当浏览器版本不受支持时，它会显示一个警告模式。目前，它接受一个配置哈希，您可以在其中传递每个浏览器不支持的最新版本

代码 这是我的应用程序中的初始值设定项

config/initializers/supportor.rb

   Supportator.configure({:chrome => 30, :ie => 11})

这是gem

lib/supportor.rb的配置文件：

   require "supportator/version"
   require "engine"

   module Supportator

     @config = {
                 :chrome => 14,
                 :safari => 5,
                 :firefox => 3,
                 :ie => 9,
                 :opera => 12
     }

     @valid_config_keys = @config.keys

     def self.configure(opts = {})
       opts.each {|k,v| @config[k.to_sym] = v if @valid_config_keys.include? k.to_sym}
     end

     def self.config
       @config
     end

   end

    ...

    if (browserName == "Chrome" && majorVersion >= <%= Supportator.config[:chrome] %>)
        supported = true;
    else if (browserName == "Safari" && majorVersion >= <%= Supportator.config[:safari] %>)
        supported = true;
    else if (browserName == "Firefox" && majorVersion >= <%= Supportator.config[:firefox] %>)
        supported = true;
    else if (browserName == "Microsoft Internet Explorer" && majorVersion >= <%= Supportator.config[:ie] %>)
        supported = true;
    else if (browserName == "Opera" && majorVersion >= <%= Supportator.config[:opera] %>)
        supported = true;
    else
        supported = false;

    ....

这是js.erb文件的一部分，它触发gem
lib/assets/javascripts/supportor.js.erb的模式：

   require "supportator/version"
   require "engine"

   module Supportator

     @config = {
                 :chrome => 14,
                 :safari => 5,
                 :firefox => 3,
                 :ie => 9,
                 :opera => 12
     }

     @valid_config_keys = @config.keys

     def self.configure(opts = {})
       opts.each {|k,v| @config[k.to_sym] = v if @valid_config_keys.include? k.to_sym}
     end

     def self.config
       @config
     end

   end

    ...

    if (browserName == "Chrome" && majorVersion >= <%= Supportator.config[:chrome] %>)
        supported = true;
    else if (browserName == "Safari" && majorVersion >= <%= Supportator.config[:safari] %>)
        supported = true;
    else if (browserName == "Firefox" && majorVersion >= <%= Supportator.config[:firefox] %>)
        supported = true;
    else if (browserName == "Microsoft Internet Explorer" && majorVersion >= <%= Supportator.config[:ie] %>)
        supported = true;
    else if (browserName == "Opera" && majorVersion >= <%= Supportator.config[:opera] %>)
        supported = true;
    else
        supported = false;

    ....

但是当我在控制台中输入supportor.config[：ie]
时，结果是12

显然，在js.erb的预编译中，配置被忽略了。有人知道为什么会发生这种情况吗？
我知道这可能没有帮助，但我无法复制您的错误。当I
RAILS\u ENV=development bundle exec rake assets:precompile
然后
RAILS s

谢谢@user2624592，您使用的是与我相同的初始值设定项吗？是的，我是。我确实注意到，如果我更改初始值设定项中的值，则不会产生任何效果。也许初始值设定项只使用一次？
