$ rvm get head && rvm重新加载

Question

我插入了下面的"$ rvm get head && rvm重新加载“，并得到了下面的输出。它说缺少目录并运行rvmsudo来解决我的问题。有人能解释我应该创建哪些目录吗？什么是"rvmsudo"？

根据输出，这是否意味着这没有正常运行？最后，它指出..。“升级/usr/local/ RVM /中的rvm已完成。”

输出：

Answer 1

如果你进入

rvm -v

并获取

rvm 1.16.12 (stable) by Wayne E. Seguin <wayneeseguin@gmail.com>, Michal Papis <mpapis@gmail.com> [https://rvm.io/]

然后安装rvm。如果没有正确安装，则可以使用

rvm implode

这将删除它，并允许您从头开始。

rvm get stable

这将为您提供最新的稳定版本。

至于什么是rvmsudo，这里有一个很好的解释
