尝试过翻墙无效，后来修改pod repo中libwebp的git source 地址，再执行pod install 解决。

解决流程

1. 查看Mac中cocoapods 本地库路径:pod repo

Mac-mini:~ ammk$ pod repo

master
- Type: git (master)
- URL:  https://github.com/CocoaPods/Specs.git
- Path: /Users/ammk/.cocoapods/repos/master

1 repo

2. 在Path中找到libwebp对应的文件夹: find /Users/ammk/.cocoapods/repos/master -iname libwebp

Mac-mini:~ ammk$ find /Users/ammk/.cocoapods/repos/master -iname libwebp
/Users/ammk/.cocoapods/repos/master/Specs/1/9/2/libwebp
Mac-mini:~ ammk$ 

进入libwebp目录，查看有哪些版本

Mac-mini:~ ammk$ cd /Users/ammk/.cocoapods/repos/master/Specs/1/9/2/libwebp
Mac-mini:libwebp ammk$ ls -l
total 0
drwxr-xr-x  3 ammk  staff  96  4  5  2017 0.4.1
drwxr-xr-x  3 ammk  staff  96  4  5  2017 0.4.2
drwxr-xr-x  3 ammk  staff  96  4  5  2017 0.4.3
drwxr-xr-x  3 ammk  staff  96  4  5  2017 0.4.4
drwxr-xr-x  3 ammk  staff  96  4  5  2017 0.5.0
drwxr-xr-x  3 ammk  staff  96  4  5  2017 0.5.1
drwxr-xr-x  3 ammk  staff  96  8  9  2017 0.5.2
drwxr-xr-x  3 ammk  staff  96  8  9  2017 0.6.0
drwxr-xr-x  3 ammk  staff  96 10 29 10:06 0.6.1
drwxr-xr-x  3 ammk  staff  96 10 30 11:17 1.0.0

在1.0.0目录下的libwebp.podspec.json文件中修改git source

Mac-mini:libwebp ammk$ cd 1.0.0
Mac-mini:1.0.0 ammk$ ls -l
total 8
-rw-r--r--  1 ammk  staff  1694 10 30 11:17 libwebp.podspec.json
Mac-mini:1.0.0 ammk$ sudo vim libwebp.podspec.json 

将其中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"
  },

再cd到原程序文件下，重新pod install。
测试 pod版本：1.5.3
