我试图安装一个json gem
gem install json
它引起了一个问题。
所以我决定卸载ruby-on-rails并重新安装。
所以现在我想在rails中执行我的项目。但是，我收到以下错误：
C:\Users\Franco\Documents\GitHub\RisePay-Ruby\Risepay>rails s
Could not find json-1.8.1 in any of the sources
Run `bundle install` to install missing gems.
我尝试再次安装Json并使用捆绑安装，但它没有用。
C:\Users\Franco\Documents\GitHub\RisePay-Ruby\Risepay>bundle install
