我再次输入 rails -v 但问题出现了！

谢谢

我试过了，但是一直没用。（无法加载 /Users/Kris/.gemrc，因为它不包含有效的 YAML 哈希错误：执行 gem 时 ... (Gem::RemoteFetcher::UnknownHostError) 没有这样的名称（api.rubygems.org/gems/tilt-2.0.1.gem).Error 似乎是关于有效的YAML 哈希。这是怎么回事？谢谢

【解决方案1】：

您的 rails gem 尚未正确安装。当我们首先安装 rails gem 时，安装所有依赖 gem，然后安装 rails。 Rails 依赖项 gem tilt 未在此处正确安装。尝试单独运行sudo gem install tilt -v='1.4.1'，然后再次运行sudo gem install rails。然后检查您的宝石列表中的rails gem。
