An error occurred while installing debugger (1.6.6), and Bundler cannot continue.
Make sure that `gem install debugger -v '1.6.6'` succeeds before bundling.

谁能给我解决方案，我很不幸地发现了...

Answer 1

这可能是 Xcode 命令行工具的问题。要做到这一点，需要执行许多步骤。

这个问题Installing Ruby Debug IDE Gem 提供了一个例子。

Answer 2

我遇到了同样的问题并通过同意xcode的许可解决了它（它似乎发生在更新之后并且你还没有同意更新）

只需从命令行运行xcodebuild -license

感谢this问题找到答案

Answer 3

上述cmets都没有帮助我。更改为下面的 ruby​​ 2.1.1 可以让我毫无问题地捆绑。

rbenv local 2.1.1
bundle install

使用 ruby​​ 2.1.2，它在同一个地方中断
