1.安装 RVM
RVM:Ruby Version Manager,Ruby版本管理器，包括Ruby的版本管理和Gem库管理(gemset)
打开控制台输入命令
curl -L get.rvm.io | bash -s stable
控制台执行命令后如下
MiaozdeMacBook-Pro:~ miaoz$ curl -L get.rvm.io | bash -s stable % Total % Received % Xferd Average Speed Time Time Time Current Dload Upload Total Spent Left Speed100 194 100 194 0 0 43 0 0:00:04 0:00:04 --:--:-- 43100 24090 100 24090 0 0 3928 0 0:00:06 0:00:06 --:--:-- 27406Downloading https://github.com/rvm/rvm/archive/1.29.3.tar.gzDownloading https://github.com/rvm/rvm/releases/download/1.29.3/1.29.3.tar.gz.ascFound PGP signature at: 'https://github.com/rvm/rvm/releases/download/1.29.3/1.29.3.tar.gz.asc', but no GPG software exists to validate it, skipping. Installing RVM to /Users/miaoz/.rvm/ Adding rvm PATH line to /Users/miaoz/.profile /Users/miaoz/.mkshrc /Users/miaoz/.bashrc /Users/miaoz/.zshrc. Adding rvm loading line to /Users/miaoz/.profile /Users/miaoz/.bash_profile /Users/miaoz/.zlogin. Installation of RVM in /Users/miaoz/.rvm/ is almost complete: * To start using RVM you need to run `source /Users/miaoz/.rvm/scripts/rvm` in all your open shell windows, in rare cases you need to reopen all shell windows.
下载完成后我们执行下上边提示的命令
source /Users/miaoz/.rvm/scripts/rvm
执行完后我们使用rvm -v 验证下是否成功。
2.使用rvm升级ruby
#查看当前ruby版本 $ ruby -v #列出已知的ruby版本 $ rvm list known #安装ruby 2.4.1$ rvm install 2.4.1
MiaozdeMacBook-Pro:~ miaoz$ ruby -v ruby 2.3.3p222 (2016-11-21 revision 56859) [universal.x86_64-darwin17]
