Error installing libwebp
1、Error installing libwebp
错误描述如下：
[!] Error installing libwebp
[!] /usr/local/bin/git clone https://chromium.googlesource.com/webm/libwebp /var/folders/9f/lkfpkvpn5j5cks24q8zgbmyc0000gn/T/d20190619-83200-lk5d3j --template= --single-branch --depth 1 --branch v1.0.2
Cloning into '/var/folders/9f/lkfpkvpn5j5cks24q8zgbmyc0000gn/T/d20190619-83200-lk5d3j'...
fatal: unable to access 'https://chromium.googlesource.com/webm/libwebp/': Failed to connect to chromium.googlesource.com port 443: Operation timed out
解决方案：
1、查看MAC系统中Cocoapods本地库路径:
执行pod repo命令：
master
- Type: git (master)
- URL: https://github.com/CocoaPods/Specs.git
- Path: /Users/illscholar/.cocoapods/repos/master
2、在本地库中, 并找到对应的libwebp版本的文件
find /Users/illscholar/.cocoapods/repos/master -iname libwebp
/Users/illscholar/.cocoapods/repos/master/Specs/1/9/2/libwebp
3、进入libwebp目录，可以看到你的仓库中有哪些对应的版本
cd /Users/illscholar/.cocoapods/repos/master/Specs/1/9/2/libwebp
4、执行ls命令查看

drwxr-xr-x 3 illscholar staff 96 6 19 20:23 1.0.2
6、由于SDWebImage 依赖的 libwebp版本为1.0.2，所以我们进入1.0.2中，并做修改
cd 1.0.2
vim libwebp.podspec.json
找到
"source": {
"git": "https://chromium.googlesource.com/webm/libwebp",
"tag": "v1.0.2"
},
将其中的"git"对应的值替换为https://github.com/webmproject/libwebp.git，并保存
7、再次执行
pod install
