Ruby 安装 for Mac(2019/9/3)

一、安装Ruby环境

1. 在终端执行下方命令，安装RVM。

最新版本应该是1.29.9
$ curl -sSL https://get.rvm.io | bash -s stable

2. 载入RVM环境

$ source ~/.rvm/scripts/rvm

3. 替换RVM下载Ruby源。

首先通过gem source查看ruby源，如果是.org替换为https://gems.ruby-china.com

leon:~ huanghaipo$ gem source
*** CURRENT SOURCES ***
https://gems.ruby-china.org
#替换源
gem source -r https://rubygems.org/
gem source -a https://gems.ruby-china.org

4. 检测是否安装正确。

rvm -v

报错，根据提示执行rvm get stable --auto-dotfiles重载。

Warning! PATH is not properly set up, /Users/huanghaipo/.rvm/gems/ruby-2.0.0-p648/bin is not at first place.
         Usually this is caused by shell initialization files. Search for PATH=... entries.
         You can also re-add RVM to your profile by running: rvm get stable --auto-dotfiles
         To fix it temporarily in this shell session run: rvm use ruby-2.0.0-p648
         To ignore this error add rvm_silence_path_mismatch_check_flag=1 to your ~/.rvmrc file.
rvm 1.29.9 (latest) by Michal Papis, Piotr Kuczynski, Wayne E. Seguin [https://rvm.io]

正常
