捆绑程序错误回溯：

您的错误来自试图捆绑您的宝石的捆绑者：

 in require': There was an error while trying to load the gem 'turbolinks'. (Bundler::GemRequireError)

---

引发此错误的原因是，在您的代码或库中的代码中，有一个名为

Turbolinks:：Source

的常量从未设置为任何值，因此代码正在调用

Turbolinks:：Source

，但由于它没有引用任何值，因此会引发错误。如果不共享代码，就很难给出更好的答案

缺少或没有与Turbolinks兼容的dep…gem“Turbolinks”、“~>5”在我的Gemfile和Turbolinks源中？我不清楚Turbolinks源下的含义谢谢帮助。Gemfile和Gemfile.lock中有不同版本的TurboLink。
