前景提要：

电脑重装系统辣，导致电脑之前安装的ruby环境以及cocoapods等其他相关环境全都没了，所以都需要重新整了，踩了好多坑，所以打算记录下来，下次可别这么折磨人了，也希望有相同问题的小伙伴少走一些弯路。之前踩坑错误的流程我就不总结了，直接贴从头到脚无痛顺利安装cocoapods的过程！！
*还有我是重装系统,所以当前系统无之前相关版本，都是重新安装的

第一步，安装命令行工具

终端输入：

 xcode-select –install

第二步，安装homebrew

详参此链接：Mac系统HomeBrew安装过程

第三步，安装ruby环境

1.终端执行这句指令：

brew install ruby

2.如果终端出现以下内容说明安装成功，但是还需要下一步设置路径问题

3.下一步配置路径问题，在终端输入以下内容：

echo 'export PATH="/usr/local/opt/ruby/bin:$PATH"' >> ~/.zshrc

4.然后终端输入以下内容，

ruby --version

5.可以查看到ruby的版本号就说明安装成功了 截屏2023-08-08 21.01.06.png

6.然后关闭终端，重启

第四步，更换ruby为国内镜像

1.先查看当前系统的ruby环境，在终端输入以下内容

gem sources -l

2.默认环境是(我没记错的话，因为我的已经是更换过的了)

*** CURRENT SOURCES ***
https://rubygems.org

3.先将系统中默认的ruby环境移除，在终端输入以下内容：

gem source -r https://rubygems.org

4.然后添加国内镜像，终端继续输入：

gem source -a https://gems.ruby-china.com

5.然后终端再输入：gem sources -l，出现以下内容就ok了

6.终于可以下一步了，累鼠了。。

第五步，终于可以开始安装cocoapods辣！

1.终端输入：

gem install cocoapods --user-install  

2.然后会出现以下内容：

3.此步骤虽然安装成功了cocoapods，但是pod命令是不好用的，如果不信叛逆的你可以试着输入 pod --version试试，会不会出现这个，我就是这一步排雷好久啊

sh: command not found: pod

4.为了让pod听从指挥，请在终端输入以下路径配置:

PATH="`ruby -e 'puts Gem.user_dir'`/bin:$PATH"

5.然后再在终端输入:

gem install cocoapods --user-install

大功已成！！！
6.可以试试输入启动"pod setup"命令，会出现绿油油的一行小字，真清爽舒适的颜色！！

接下来就可以想干嘛干嘛辣，管理你得第三方库辣
如果铁铁们还有遇到其他的问题留言大家一起🍑

**注意
在项目中pod install 之后 会出现以下问题

[!] CDN: trunk URL couldn‘t be downloaded: https://raw.githubusercontent.com/CocoaPods/Specs/master/

解决思路详参(亲测有效)：在podfile文件中添加指定的spec repo源
