2. 导入 RVM 官方 GPG 密钥
某些 Ruby Gem 可能需要编译本地扩展，需安装构建工具和依赖库：

3. 安装 RVM
直接通过 RubyGems 安装：

➜ /opt curl -sSL https://get.rvm.io | bash -s stable

Creating group 'rvm'
Installing RVM to /usr/local/rvm/
source /etc/profile
Installation of RVM in /usr/local/rvm/ is almost complete:
* First you need to add all users that will be using rvm to 'rvm' group,
and logout - login again, anyone using rvm will be operating with `umask u=rwx,g=rwx,o=rx`.
* To start using RVM you need to run `source /etc/profile.d/rvm.sh`
in all your open shell windows, in rare cases you need to reopen all shell windows.
* Please do NOT forget to add your users to the rvm group.
The installer no longer auto-adds root or users to the rvm group. Admins must do this.
Also, please note that group memberships are ONLY evaluated at login time.
This means that users must log out then back in before group membership takes effect!
Thanks for installing RVM 🙏
Please consider donating to our open collective to help us maintain RVM.
