iOS使用cocoapods 安装 libwebp0.6.0 遇

原文地址

可能会遇到libwebp v0.6.0 超时问题:

[!] Error installing libwebp

fatal: unable to access 'https://chromium.googlesource.com/webm/libwebp/': Failed to connect to chromium.googlesource.com port 443: Operation timed out

解决方法:
尝试过翻墙，修改host，均无效
最终，修改pod repo中libwebp的git source 地址，再执行pod install解决，
但是我们需要有一个有效的libwebp的git仓库，在github上找到了一个https://github.com/webmproject/libwebp.git，可以看到mirrored from https://chromium.googlesource.com/webm/libwebp，而且正好有我需要的版本0.6.0, 那么我就替换为这个。
下面是步骤:

1. 查看mac中cocoapods 本地库路径:

//以下在终端中打开
 pod repo

/Users/swae/.rbenv/versions/2.5.0/lib/ruby/gems/2.5.0/gems/cocoapods-1.4.0/lib/cocoapods/executable.rb:89: warning: Insecure world writable dir /opt in PATH, mode 040777

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

2. 在本地库中, 并找到对应的libwebp版本的文件

//以下在终端中打开
find ~/.cocoapods/repos/master -iname libwebp

/Users/liguangliang/.cocoapods/repos/master/Specs/1/9/2/libwebp

进入libwebp目录，可以看到你的仓库中有哪些对应的版本

liguangliangdeMac-mini:~ liguangliang$ cd /Users/liguangliang/.cocoapods/repos/master/Specs/1/9/2/libwebp
liguangliangdeMac-mini:libwebp liguangliang$ ls -l

total 0
drwxr-xr-x  3 liguangliang  staff  102 10 16 12:02 0.4.1

drwxr-xr-x  3 liguangliang  staff  102 10 16 12:02 0.5.2
drwxr-xr-x  3 liguangliang  staff  102 10 16 12:02 0.6.0
drwxr-xr-x  3 liguangliang  staff  102 11  5 15:31 0.6.1
drwxr-xr-x  4 liguangliang  staff  136 11  5 15:31 1.0.0

由于SDWebImage 依赖的 libwebp版本为0.6.0，所以我们进入0.6.0中，并做修改

cd 0.6.0/

ls -l

total 8
-rw-r--r--@ 1 swae  staff  1587  4 15 09:53 libwebp.podspec.json

在0.6.0目录下的libwebp.podspec.json文件中修改git source

sudo vim libwebp.podspec.json

找到

"source": {
"git": "https://chromium.googlesource.com/webm/libwebp",
"tag": "v0.6.0"
},

将其中的"git" 对应的url替换为https://github.com/webmproject/libwebp.git,并保存
最后再执行pod install

完成
