【参考方案1】：

您的PATH 中似乎有/Users/mmoser/.rvm/scripts/，这不是偶然发生的 - 您必须手动添加它，请删除它并重新安装 gem。

还需要重新安装ruby，因为INSTALL被记录在ruby中：

$ rvm config-get INSTALL
/usr/bin/install -c

所以运行：

rvm reinstall all

【讨论】：

我从我的 Dropbox 帐户中为我的 dot 文件添加别名，该路径是其他东西的残余。感谢您说服我清理我的 PATH 声明，这是非常需要的；）唉，我的问题仍然存在。 （当前路径添加到问题）

砰！就是这样，很棒的酱汁。非常感谢。
