I need to free disk space on my local machine, which is almost allocated into my Ruby Version Manager (RVM) dir.
我需要释放本地计算机上的磁盘空间，这几乎分配到我的Ruby版本管理器（RVM）目录中。
Now, it seems I got just one ruby version ( 1.9.2p136 ) :
现在，我似乎只有一个ruby版本（1.9.2p136）：
lsoave@ubuntu:~/rails/github/gitwatcher$ ruby -v
ruby 1.9.2p136 (2010-12-25 revision 30365) [i686-linux]
lsoave@ubuntu:~/rails/github/gitwatcher$

but my RVM dir, have many others unrelated dirs/versions :

is it save to remove all dirs remaining with just "ruby-1.9.2-p136" and "ruby-1.9.2-p136@global" dirs (ruby-1.9.2-p136@greendog* are old and "rvm system" return nothing) ? Will I use "rm" command, or are there RVM embodied commands to cleanup a better way ? Is it possible cleanup the cache dir ?
只用“ruby-1.9.2-p136”和“ruby-1.9.2-p136@global”dirs（ruby-1.9.2-p136@greendog *旧版和“rvm系统”）删除剩余的所有目录没有回报）？我会使用“rm”命令，还是有RVM体现的命令来清理更好的方法？是否可以清理缓存目录？
Thanks in advance. luca

I suppose rvm cleanup could do the trick.
我想rvm清理可以做到这一点。
Other than that I don't see any reason that deleting the actual gem directories inside RVM if they aren't associated with RVM any more.
除此之外我没有看到任何理由删除RVM中的实际gem目录，如果它们不再与RVM相关联。
If the matching entry doesn't exist in environments then it is safe to delete the accompanying gem dir. As nothing else points to it that RVM would be able to use.
如果环境中不存在匹配的条目，则可以安全地删除附带的gem目录。正如RVM能够使用的其他内容一样。

... it turn out that some of the previous, not used refs, were just gemsets:
...事实证明，之前的一些未使用的引用只是gemsets：
rvm gemset list

which I removed like following:
我删除了如下：
lsoave@ubuntu:~$ rvm gemset delete greendog99
Are you SURE you wish to remove the entire gemset directory 'greendog99' (/home/lsoave/.rvm/gems/ruby-1.9.2-p136@greendog99)?

我做了一个旧的'lib'备份（以防万一......）：

and removed the relative directory as a previous comment talk, with stuartc:
并删除了相关目录作为之前的评论谈话，与stuartc：

now back to work.
现在回去工作了。
I'll wait a couple of days, looking for everything is right ...
我会等几天，寻找一切都是对的......
