如何使用RVM安装Ruby 2.2.2

Question

我运行rvm -v并返回rvm 1.29.1所以我运行rvm install 2.2.2来升级Ruby版本。

显示：

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

我再次运行rvm -v并显示rvm 1.29.1。这意味着RVM没有安装或无法正常工作。有什么建议吗？

Answer 1

你试过了吗？

$ rvm use 2.2.2

Answer 2

RVM和ruby是两回事。

您正在运行RVM -v以获取应该执行的ruby版本

ruby -v 

使用rvm

回答要安装的问题

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

Answer 3

我是在CentOS 6.5上做到的：

1. 使用gpg更新密钥（请参阅此处https://rvm.io/rvm/install）
2. 安装rvm：curl -sSL https://get.rvm.io | bash -s stable
3. 安装ruby：rvm install ruby-2.2.2
