我刚买了一台新笔记本电脑，并使用 Migration Assistant 完全转移了所有内容。似乎一切正常并且在适当的位置，所以我不知道这是否是问题所在。我对调试这样的环境错误还是很陌生。

我一直在 Windows 上开发一个 rails 项目，这台笔记本电脑是 Mac OS X 10.8。我之前在上面克隆了一个 GitHub 项目，它运行良好。这是github repo供参考。这个项目在我运行 bundle 时遇到错误

尝试将此添加到我的 gemfile

gem 'json', '1.8.0'

现在我在 bundle update json 之后得到了这个新错误...我的上一个项目也只在生产中使用了 Postgres，但是当我捆绑那个时我没有看到 pg gem。

You have requested:

json = 1.8.0

The bundle currently has json locked at 1.8.1.
Try running `bundle update json`
Run `bundle install` to install missing gems.

有什么线索吗？

您可能需要安装 Xcode 控制台工具，至少这是我遇到的问题。

你可以通过运行来做到这一点：

xcode-select --install
