错误信息如下：

Installing libwebp 1.2.0
[!] Error installing libwebp

解决办法：
1、pod repo 查看 cocoapods 在本机的PATH
2、拼接地址：由1所得出path拼接为，path/Specs/1/9/2/libwebp
3、右键finder前往文件夹，将2所得地址输入，前往
4、打开你要加载的版本相应的文件夹，如我的错误信息为Installing libwebp (1.2.0)，则用文本编辑打开1.2.0文件夹的json文件
5、将json中source下git地址更改为https://github.com/webmproject/libwebp.git
也可以直接cd /Users/mac/.cocoapods/repos/master/Specs/1/9/2/libwebp
其中mac是你的电脑用户名，作参考
经过上面操作真的可以成功 ？
笔者体验了 却没有
看我的：
pod repo
mac$ pod repo

4 repos
有4个repos 不清楚用的那个话 只能一个个去操作，因为我用的可能不是master 下的
/Users/mac/.cocoapods/repos/master/Specs/1/9/2/libwebp
可能是：
/Users/mac/.cocoapods/repos/trunk/Specs/1/9/2/libwebp
/Users/mac/.cocoapods/repos/tsinghua-git-cocoapods/Specs/1/9/2/libwebp
需要每个操作下。最后 pod install 就好了
-----------20231012更新-----------------------
用这个源：
source 'https://mirrors.tuna.tsinghua.edu.cn/git/CocoaPods/Specs.git'
其他的源（github的）失效了
