Flutter: Error running pod install解决

错误信息：

……这里省略一堆信息，重点在开头和结尾的Error……

Error output from CocoaPods:

这是由于被墙了无法克隆导致的，解决方法提供两个：

一、直接使用代理并全局

二、修改git地址为可访问镜像库

1、进入 libwebp 目录下

cd ~/.cocoapods/repos/trunk/Specs/1/9/2/libwebp/

2、找到最新版本，如上图 1.1.0 并进入

cd 1.1.0

3、编辑 libwebp.podspec.json

vim libwebp.podspec.json

4、修改 git 仓库地址

"source": {
"git": "https://chromium.googlesource.com/webm/libwebp",
"tag": "v1.1.0"
}

修改成：

"source": {
"git": "https://github.com/webmproject/libwebp.git",
"tag": "v1.1.0"
}

改完重试下，应该好了！
