': undefined local variable or method `rsion' for main:Object (NameError)

查看 ruby 版本的命令为 ruby -v

如果执行命令 ruby -version 会显示 ruby 的版本信息同时也会显示错误信息 -e:1:in <main>': undefined local variable or methodrsion' for main:Object (NameError)

是因为执行错误的命令 ruby -version，任务 ruby -ve 后面的 rison 为命令参数

并不是，你试试

ruby -ve rsion

然后看看 -e 是干嘛的就知道了
