Errno :: EACCES：运行bundle时权限被拒绝，它命中json 1.8.1，pg 0.17

Question

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。 看起来一切正常并处于适当的位置，所以我不知道这是不是问题。 我仍然是调试这样的环境错误的新手。

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。 我之前已经克隆了一个GitHub项目，它运行良好。 这是github回购供参考。 当我运行bundle时，这个项目会出错

尝试将此添加到我的gemfile中

gem 'json', '1.8.0'

现在我在捆绑更新json之后得到这个新错误...我的最后一个项目也只在生产中做了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.

有线索吗？

您可能需要安装Xcode控制台工具，至少是我遇到的问题。

你可以通过运行：

xcode-select --install
