在安装Ruby on Rails时，发现需要Ruby版本为2.2.2或更高。通过RVM（Ruby Version Manager）进行升级，首先检查RVM安装，然后查看并选择合适的Ruby版本进行升级，确保兼容性。

在安装 Ruby on Rails 时遇到问题，提示依赖 ruby 2.2.2 或更高的版本。

ERROR:  Error installing rails:
	activesupport requires Ruby version >= 2.2.2.

一、使用RVM也就是Ruby Version Manager,Ruby版本管理器来升级ruby，RVM包含了Ruby的版本管理和Gem库管理(gemset)。（以下命令都在终端中进行，因为基本都是命令行我就不上图了，终端的提示也比较清晰）

1、安装RVM

$ curl -L get.rvm.io | bash -s stable

命令输出：

Downloading https://github.com/rvm/rvm/archive/1.29.2.tar.gz
Downloading https://github.com/rvm/rvm/releases/download/1.29.2/1.29.2.tar.gz.asc
Found PGP signature at: 'https://github.com/rvm/rvm/releases/download/1.29.2/1.29.2.tar.gz.asc',
but no GPG software exists to validate it, skipping.

Installing RVM to /Users/aven/.rvm/
    Adding rvm PATH line to /Users/aven/.profile /Users/aven/.mkshrc /Users/aven/.bashrc /Users/aven/.zshrc.
    Adding rvm loading line to /Users/aven/.profile /Users/aven/.bash_profile /Users/aven/.zlogin.
Installation of RVM in /Users/aven/.rvm/ is almost complete:

  * To start using RVM you need to run `source /Users/aven/.rvm/scripts/rvm`
    in all your open shell windows, in rare cases you need to reopen all shell windows.

# aven,
#
#   Thank you for using RVM!
#   We sincerely hope that RVM helps to make your life easier and more enjoyable!!!
#
# ~Wayne, Michal & team.

In case of problems: https://rvm.io/help and https://twitter.com/rvm_io

  * WARNING: You have '~/.profile' file, you might want to load it,
    to do that add the following line to '/Users/aven/.bash_profile':

      source ~/.profile

可以看到最后有一条警告，需要执行：

source ~/.profile

主要作用应该就是更新环境变量。

2、测试是否安装成功

rvm -v

直接执行 rvm 不带参数会显示帮助信息。
