HomeBrew 安装

brew -v
zsh: command not found: brew
无HomeBrew 则安装
执行命令： /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

出现问题：直接访问出现443问题
curl: (28) Failed to connect to raw.githubusercontent.com port 443 after 75005 ms: Couldn't connect to server

出现443等情况是访问外国有限制，改成国内清华的

1、先查github国外IP地址
https://www.ipaddress.com/ip-lookup

输入github.com 出现内容是140.82.121.3 github.com

修改host

命令：sudo vim /etc/hosts
添加 esc -> i ->esc退出：wq
增加以下内容
140.82.121.3 github.com
199.232.28.133 raw.githubusercontent.com

199.232.28.133 raw.githubusercontent.com 是安装rvm

正确方法 HomeBrew安装国内清华

命令： /bin/zsh -c "$(curl -fsSL https://gitee.com/cunkai/HomebrewCN/raw/master/Homebrew.sh)"
(参考HomeBrew安装国内清华)[https://blog.csdn.net/weixin_38716347/article/details/123838344]

检查安装完HomeBrew版本即安装成功
apple@bogon ~ % brew -v
Homebrew 4.3.13

rvm安装

1、curl -L https://raw.githubusercontent.com/wayneeseguin/rvm/master/binscripts/rvm-installer | bash -s stable

2、source ~/.rvm/scripts/rvm

3、查看版本 rvm -v 安装成功
rvm 1.29.12 (latest) by Michal Papis, Piotr Kuczynski, Wayne E. Seguin [https://rvm.io]

ruby安装

brew install ruby
rvm install ruby
执行以上任意一个命令安装ruby后版本还是系统的版本ruby 2.6.10，则用brem中rvm替换Mac系统中的版本ruby 2.6.10p210 (2022-04-12 revision 67958)

命令是：
1、echo 'export PATH="/usr/local/opt/ruby/bin:$PATH"' >> ~/.profile
2、source ~/.profile

3.查看ruby版本 ruby -v 版本号大于2.6.10则ruby更新成功
ruby 3.3.2 (2024-05-30 revision e5a195edf6) [x86_64-darwin22]

安装cocoapods

2.查看源(目的:检测rudy的源)

5.查看是否更新成功(目的:检测是否替换成功)
