使用rvm,可以管理多个ruby版本,以适应各种项目的ruby版本需求,每次进入项目时,就可以手动指定ruby版本,像这样:

$ rvm use 2.6.5

为了不用每次都输入这个命令,参考rvm官网文档以及这篇博客1. 我们不仅给项目指定ruby版本,还为项目生成一个独立的gem管理目录.

我当前用的ruby版本是2.6.5,博客路径在/Users/chenjing/workspace/github/gnuser.github.io.

创建gemset

✗ rvm gemset create gnuser_blog
ruby-2.6.5 - #gemset created /Users/chenjing/.rvm/gems/ruby-2.6.5@gnuser_blog

指定ruby版本

✗ rvm --rvmrc ruby-2.6.5@gnuser_blog
Using /Users/chenjing/.rvm/gems/ruby-2.6.5 with gemset gnuser_blog

确认配置

gnuser.github.io git:(master) ✗ cd ../
➜  github cd gnuser.github.io
You are using '.rvmrc', it requires trusting, it is slower and it is not compatible with other ruby managers,
you can switch to '.ruby-version' using 'rvm rvmrc to ruby-version'
or ignore this warning with 'rvm rvmrc warning ignore /Users/chenjing/workspace/github/gnuser.github.io/.rvmrc',
'.rvmrc' will continue to be the default project file in RVM 1 and RVM 2,
to ignore the warning for all files run 'rvm rvmrc warning ignore all.rvmrcs'.
