rubygems 更新破坏了 OSX 上的 ruby
我在运行一些 Ruby 脚本时遇到了一些问题。在尝试运行这些脚本时,我尝试了很多不同的方法以及更新 rubygems,因为我认为这可能是问题所在。从那时起我就无法运行任何 Ruby 脚本了。
我认为如果我可以将 rubygems 恢复到其原始版本,我也许可以再次运行 Ruby 脚本,但我不知道如何操作。

I was having some trouble running some Ruby scripts. While trying to get these scripts to run I tried lots of different things as well as updating rubygems as I thought this may be the problem. Since then I can't get any Ruby scripts to run.
I think that if I can revert rubygems back to it's original version I may be able to run Ruby scripts again, but I don't know how.

您似乎安装了多个版本的 ruby(和 gem)。维护多个 ruby 版本时建议使用
rvm
。或者清理错误/旧的/不需要的安装。It seems that you have multiple versions of ruby(and gem) installed. It is advised to use
rvm
when maintaining multiple ruby versions. Or clean up your wrong/old/unneeded installations.要降级 Rubygems,您可以执行以下操作:
显然您必须在那里放置一个真实版本。
For downgrading Rubygems, you can do the following:
You obviously have to put a real version there.
