在我努力让RVM与Textmate一起工作并且RVM行为变得奇怪之后重新安装(报告它没有列出的gemsets)所以我运行：

rvm implode

…然后手动删除可执行文件.然后我严格按照single user instructions from the home site.运行安装

在发现错误之后,我调查了路径,发现?/ .rvm / scripts /和?/ .rvm / src / rvm / scripts /中的许多文件显然应该是可执行的,但没有执行权限.

RVM根本不会运行所以我在两个目录中的所有文件上设置了可执行位,这似乎有固定的东西. (至少到目前为止.)

谷歌搜索,似乎其他人已经遇到了这个问题,但似乎没有解释或解决方案.我想知道这是否是一个已知问题以及我是否应该重新安装.

我在MacOS X 10.6.7上运行rvm 1.6.9
