brew install ruby时报错

Posted 2023-04-17

执行$ brew install ruby时，运行结果如下：
Updating Homebrew...
Error: You must `brew link makedepend` before ruby can be installed

ruby -v:ruby 2.0.0p645 (2015-04-13 revision 50299) [universal.x86_64-darwin15]
rails -v:Rails 4.2.5.1

起因：
在rails项目目录下启动rails server时，提示
$ rails s
Your Ruby version is 2.0.0, but your Gemfile specified 2.2.1
所以想要升级ruby，但总是安装不成功，求大神解答

参考技术A 最好用rvm ruby version manager。

mac install brew

$ ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
