on this machine.←[0m
←[33mRun `bundle install` to install missing gems.←[0m

but whenever I then do a bundle install to install the missing gem, I get this error:

但每当我进行捆绑安装以安装缺少的gem时,我会收到此错误:

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

I then tried to install json without any luck. Any suggestions?

然后我试着安装json而没有任何运气。有什么建议?

Since you're on Windows, you need to install the Development Kit to be able to build gems with native extensions.

由于您使用的是Windows,因此需要安装开发工具包才能构建具有本机扩展的gem。
