当尝试使用 RVM 在我的 OS 10.7 MBP 上安装 Ruby 1.9.3 时，我遇到了一个无限循环，因为它试图找到另一个 Ruby 来进行安装:
$ rvm system
$ rvm install 1.9.3
Searching for binary rubies, this might take some time.
No binary rubies available for: osx/10.7/x86_64/ruby-1.9.3-p448.
Continuing with compilation. Please read 'rvm help mount' to get more information on binary rubies.
Warning! Requested ruby installation which requires another ruby available - installing one first.

^C
To proceed rvm requires a ruby-1.9|ruby-2 compatible ruby is installed.
We attempted to install ruby automatically but it failed.
Please install it manually (or a compatible alternative) to proceed.

当然，这里有一颗 ruby ，否则我们就不会走那么远:
$ which ruby
/usr/bin/ruby
$ ruby -v
ruby 1.8.7 (2012-02-08 patchlevel 358) [universal-darwin11.0]
知道是什么原因造成的，以及如何解决？
最佳答案
我最近在使用 ruby-1.8.7 的 OS X 10.8 上遇到了类似的问题。升级 rvm 对我有帮助。我已经完成了:
$ rvm get stable
然后:
$ rvm use system
$ rvm install 1.8.7-p374
