我没有永久解决它，但我找到了一个解决方案来规避错误。 当我给一个新的轨道，它生成的宝石文件中，将指定的轨道版本，我只是改变了产生的Gemfile，我“创造”的一个：

gem 'openssl', '2.0.4'

我不能使用rbenv也不rvm升级我的导轨，所以我做这个“调整”。
'rails g scaffold用户名电子邮件'适用于我。然而，这个警告意味着你正在运行带有旧版Rails的Ruby的最新版本。升级Rails（或降级Ruby）可以解决这个问题。 – Stefan
我该怎么做？我已经尝试过原始文档，但我不知道该怎么做......我不明白该怎么做。 –
我认为值得让Rbenv（我使用这个）或rvm（我在MacOSX上遇到了几个与rvm相关的问题），以便管理你的ruby的东西。它们允许下载和安装ruby版本，为某些项目设置“全局”ruby版本和gem set，和/或本地ruby版本以及所需的gemset。我发现它安装和使用非常紧张。 –
