这是由于被墙了无法克隆导致的

解决方案

具体操作如下：

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"
}

最后尝试下就OK了
