https://chromium.googlesource.com/webm/libwebp 被墙
更换下载源 找到对应文件

 find ~/.cocoapods/repos/master -iname libwebp
/Users/you_mac_name/.cocoapods/repos/master/Specs/1/9/2/libwebp

修改libwebp.podspec.json文件：

"git": "https://chromium.googlesource.com/webm/libwebp"
为
"git": "https://github.com/webmproject/libwebp"

重新执行pod install --verbose --no-repo-update即可

cocoapod 1.8.+之后

默认为源为https://cdn.cocoapods.org/

执行pod install --verbose --no-repo-update

出现

此时同样的方法应该去 trunk中去修改

find ~/.cocoapods/repos/trunk -iname libwebp
/Users/yuehuig/.cocoapods/repos/trunk/Specs/1/9/2/libwebp

找到对应的文件
修改libwebp.podspec.json文件：

"git": "https://chromium.googlesource.com/webm/libwebp"
为
"git": "https://github.com/webmproject/libwebp"

重新执行pod install --verbose --no-repo-update即可
