Ruby on rails 已停止Gem更新，现在Rails不是'；无法识别并取消安装/重新安装未安装的'；行不通

我对这一点很陌生，所以如果有一个简单的解决办法，我很抱歉，如果您愿意回答，请一步一步地具体说明

这就是我得到的。。。谢谢

我想你可以试试“rvm重新安装1.9.3-p392”。。。不确定这是否有效，但值得一试。我想这只是一个评论，而不是一个答案，但我还没有足够的代表来做这件事，我不认为。

很可能你的~/.gemrc文件中有一个输入错误，应该是：

install: --no-rdoc --no-ri
update: --no-rdoc --no-ri

注意你的标签。“fix”是指fix协议，而不是当你需要修复某些东西时。还有其他建议吗？？我不明白为什么完全删除ruby和rails并重新安装没有起作用…这没有起作用，我也不明白Pigueiras的第一个建议…谢谢你的尝试！
