Question

我在启动Rails Web服务器时遇到问题。我尝试在cmd提示符下输入“rails server”但我收到以下错误：

C:\Ruby193\demo>rails server
←[31mCould not find gem 'jquery-rails (>= 0) x86-mingw32' in the gems available
on this machine.←[0m
←[33mRun `bundle install` to install missing gems.←[0m

但每当我进行捆绑安装以安装缺少的gem时，我都会收到此错误：

C:\Ruby193\demo>bundle install

Gem files will remain installed in C:/Ruby193/lib/ruby/gems/1.9.1/gems/json-1.6

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.

然后我尝试安装json而没有任何运气。有什么建议吗？

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原生扩展的gem。
