Rails4：如何提供特定于 gem 的 javascript 文件？

Question

我将一个正常工作的 Rails 应用程序复制到了不同的目录中，并使用重命名 Gem 对其进行了重命名。

大多数 rails 功能都可以正常工作，但我无法提供与 gems 捆绑的资产，特别是来自 bootstrap-slider-rails 的 js 文件

我比较了我的 application.rb 、 Gemfile 和 application.js ，它们在两个应用程序中是相同的。

我已尝试再次卸载和安装 gem

应用之间的简单比较并不能解决问题。

以下是我验证的两个应用程序中相同的文件：

1. 宝石文件
2. application.rb
3. application.html.haml
4. application.js

有什么建议我应该如何调试？

谢谢！

以下是一些相关文件的外观：

#if defined?(Bundler)

#  # If you want your assets lazily compiled in production, use this line
#  # Bundler.require(:default, :assets, Rails.env)

Bundler.require(:default, Rails.env)

    config.encoding = "utf-8"

    # Configure sensitive parameters which will be filtered from the log file.

    config.active_record.schema_format = :sql



    # Enable the asset pipeline
    config.assets.enabled = true

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

    #Prevent initializing the application and connecting to db on bootup as required by heroku

    # Not required on rails4 anymore
    #config.assets.initialize_on_precompile = false

    #config.action_view.javascript_expansions[:defaults] = %w(jquery.min jquery_ujs)

尝试删除您的 gemfile.lock 并再次运行 bundle install。

另请参阅this SO 关于复制和部署 Rails 应用程序的帖子。如果没有，您应该删除 .git 文件并运行 git init。

我不是 100% 确定这会解决您的问题，但我怀疑您遇到了 gem 问题。
