如何使用RVM安装Ruby 2.2.2

Question

我跑了rvm -v,它返回rvm 1.29.1所以我跑去rvm install 2.2.2升级Ruby版本.

这显示了:

ruby-2.2.2 - #removing rubies/ruby-2.2.2..
Searching for binary rubies, this might take some time.

我rvm -v再次跑了,它表明了rvm 1.29.1.这意味着RVM没有安装或无法正常工作.有什么建议？

你有没有尝试过:

Answer 2

RVM和红宝石是两个不同的事物。

您应该在运行RVM -v时获取红宝石版本

ruby -v 

回答使用rvm安装的问题

rvm install <version>
rvm use <version>
ruby -v
