mac如何升级ruby到2.4.0

Question

先来一发。我这种版本帝是无药可救的。
macos是最新系统多少我不记得了。。。正常通道最新的就对了
目前ruby版本是2.3.1。
我用rvm 无法升级到2.4.0或者2.3.3，请问怎么升级呢？

oops。。报错内容我背不出来。mac不在手边

Answer 1

First install the MAC package management program Homebrew and enter it in the terminal

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

Then use Homebrew to update Ruby:

brew install ruby

Answer 2

1. Compile it yourself

2. homebrew

3. rbenv or rvm

If it doesn’t take effect, there may be something wrong PATH
