[英]Unable to run rails server: `require': cannot load such file — net/ssh (LoadError)
我正在尝试使用michael hartl指南在轨道上学习红宝石。 在过去，我能够完成新的rails webapp的设置。 现在，当我尝试运行服务器时，我收到此错误：

或者，将其添加到您的Gemfile：
gem 'fog', '~> 1.36.0'
并运行bundle install 。 这对我1.35.0 ，因为我遇到了1.35.0引入的错误： https ： //github.com/fog/fog/issues/3765
将其添加到您的Gemfile：
gem 'net-ssh'
然后运行bundle install 。
