Did you install Ruby before installing rails? I ran into the same problem until I went to https://help.ubuntu.com/community/RubyOnRails#Get%20Ruby. There are a number of steps you have to take before you install rails and I think this will help, if you are running it on the Ubuntu OS. Hope it works for you!
你在安装 Rails 之前安装了 Ruby 吗？我遇到了同样的问题，直到我去https://help.ubuntu.com/community/RubyOnRails#Get%20Ruby。在安装 rails 之前，您必须采取许多步骤，如果您在 Ubuntu 操作系统上运行它，我认为这会有所帮助。希望这对你有用！
