解决办法：
查看cocoapods 本地库路径:pod repo
$ pod repo
master
- Type: git (master)
- URL: https://github.com/CocoaPods/Specs.git
- Path: /Users/ammk/.cocoapods/repos/master
1 repo
在文件夹下找到libwebp的文件夹: find ~/.cocoapods/repos/master -iname libwebp
find ~/.cocoapods/repos/master -iname libwebp
输出
/Users/ammk/.cocoapods/repos/master/Specs/1/9/2/libwebp
查看libwebp下版本：
$ cd ~/.cocoapods/repos/master/Specs/1/9/2/libwebp
$ ls -l

cd到1.1.0版本，修改libwebp.podspec.json文件中的homepage,source->git。
$ cd 1.1.0
$ ls -l
total 8
-rw-r--r-- 1 huanghaipo staff 1854 2 17 10:09 libwebp.podspec.json
修改
$ sudo vim libwebp.podspec.json
将homepage改为https://github.com/webmproject/,source->git改为https://github.com/webmproject/libwebp.git
"name": "libwebp",
"version": "1.0.0",
"summary": "Library to encode and decode images in WebP format.",
"homepage": "https://developers.google.com/speed/webp/",
"authors": "Google Inc.",
"license": {
"type": "BSD",
"file": "COPYING"
},
"source": {
"git": "https://chromium.googlesource.com/webm/libwebp",
"tag": "v1.0.0"
},
修改完就大功告成，接下来cd到工程目录下，执行pod install
image
后面再次去执行pod install还是报上面的错误，检查master下的libwebp.podspec.json文件正常。那原因应该是多了trunk源，修改过 trunk后，还是有点问题，但是可以下载下来，最后执行 pod repo remove trunk删除trunk源，运行pod install 。OK
