错误:执行gem时...(Gem :: FilePermissionError)

Question

$ gem install passenger
Fetching: passenger-4.0.5.gem (100%)
ERROR:  While executing gem ... (Gem::FilePermissionError)
You don't have write permissions for the /Users/snowcrash/.rvm/gems/ruby-2.0.0-p195 directory.
$ ls -ld /Users/snowcrash/.rvm/gems/ruby-2.0.0-p195
drwxrwsr-x  8 root  rvm  272 21 May 16:07 /Users/snowcrash/.rvm/gems/ruby-2.0.0-p195

很明显,我的ruby版本归root/rvm所有.

我对这个SO答案表示不满意,这个答案表明.gem/specs是世界可写的: RVM的权限被拒绝错误

这个答案是针对特定的宝石: 执行gem时出错......权限被拒绝

有更好的建议吗？

也许修复.rvm目录的权限/所有权？

Answer 1

RVM有一个修复权限的命令:

rvm get head
rvm fix-permissions
