fatal: unable to access 'https://chromium.googlesource.com/webm/libwebp/': Failed to connect to chromium.googlesource.com port 443: Operation timed out
原因：天朝无法访问国外的源，需要进行更换源 查找到cocoapod文件夹下
.cocoapods/repos/cocoapods/Specs/1/9/2/libwebp/1.0.2/libwebp.podspec.json
1.0.2是版本号，查找对应的版本号更改source的git更改为https://github.com/webmproject/libwebp.git
"source": {
"git": "https://github.com/webmproject/libwebp.git",
"tag": "v1.0.2"
},
