将 rails 3 升级到 rails 4.2.4 后，我想在我的项目中使用 react-rails gem
。rake webpacker:install收到此错误。

请帮助我，我使用 Rails 4.2.4 创建了一个新的演示应用程序，它工作正常，但不是我现有的应用程序。
将此文件放入文件夹/Users/YourAPP/config https://github.com/rails/webpacker/blob/master/lib/install/config/webpacker.yml
这是 3 步过程：
- 第 1 步：在配置文件夹中创建一个 webpacker.yml，以便路径为 config/webpacker.yml
- 第 2 步：将以下内容粘贴到 webpacker.yml 文件中。
