我被这个问题发疯了。我已经安装了 rvm 并重新安装了一百万次，但它就是不工作。
我全新安装了 centOS 6.3，当我去安装 rvm 时，它完成了，但是在安装 ruby 时给了我一个奇怪的错误。这是跟踪：
[pushprod@ruby-prod webapps]$ \curl -#L https://get.rvm.io | bash -s stable --autolibs=3 --ruby

# In case of any issues run 'rvm requirements' or read 'rvm notes'
Installation of RVM in /home/pushprod/.rvm/ is almost complete:
* To start using RVM you need to run `source /home/pushprod/.rvm/scripts/rvm`
in all your open shell windows, in rare cases you need to reopen all shell windows.
# pushprod,

# Thank you for using RVM!
# I sincerely hope that RVM helps to make your life easier and
# more enjoyable!!!

Searching for binary rubies, this might take some time.
No binary rubies available for: centos/6.4/x86_64/ruby-2.0.0-p195.
Continuing with compilation. Please read 'rvm mount' to get more information on binary rubies.
Installing requirements for centos, might require sudo password.
There is no checksum for 'https://dl.fedoraproject.org/pub/epel/RPM-GPG-KEY-EPEL-6' or 'RPM-GPG-KEY-EPEL-6', it's not possible to validate it.
This could be because your RVM install's list of versions is out of date. You may want to
update your list of rubies by running 'rvm get stable' and try again.
If that does not resolve the issue and you wish to continue with unverified download
add '--verify-downloads 1' after the command.
