+# 解决 CocoaPods 命令 pod install 安装 github.com 上的包非常缓慢或者失败
+
+CocoaPods 执行 `pod install` 会安装 `github.com` 上的包，但 `github.com` 很不稳定。
+一个解决方案是，使用脚本将 `github.com` 的资源转换为其他域的资源。
+
+## CocoaPods v1.7.2
+
+CocoaPods 从 1.7.2 版本开始使用 `https://cdn.cocoapods.org/` 代替原有的 `https://github.com/CocoaPods/Specs.git`，
+这样可以按需下载需要的包定义，而不用一次性下载整个 `Specs` 库（整个库是 3GB 左右），参考 [CocoaPods 1.7.2 — Master Repo CDN is Finalized!](https://blog.cocoapods.org/CocoaPods-1.7.2/)。
+
+```
+source 'https://github.com/artsy/Specs.git'
+- source 'https://github.com/CocoaPods/Specs.git'
++ source 'https://cdn.cocoapods.org/'
+```
+
+## 解决方案
+
+脚本是使用 `python` 写的，很简单，放在 `https://github.com/senntyou/CocoaPods-Specs-Modify`，如要使用，需要先克隆到本地。
+
+```
+git clone https://github.com/senntyou/CocoaPods-Specs-Modify.git
+
+cd CocoaPods-Specs-Modify
+
+python modify.py
+```
+
+`modify.py` 脚本中，默认 `specsDir` 取 `~/.cocoapods/repos/trunk/Specs/`，`targetSite` 取 `github.com.cnpmjs.org/`，可以根据需要更改，再运行脚本
+
+```
+# Specs目录
+specsDir = os.path.expanduser('~') + '/.cocoapods/repos/trunk/Specs/'
+
+# github 域名
+githubSite = 'github.com/'
+
+# 替换域名
+targetSite = 'github.com.cnpmjs.org/'
+```
+
+## 示例
+
+比如，原来的包定义是
+
+```
+{
+  "name": "MJRefresh",
+  "version": "3.6.1",
+  "summary": "An easy way to use pull-to-refresh",
+  "homepage": "https://github.com/CoderMJLee/MJRefresh",
+  "license": "MIT",
+  "authors": {
+    "MJ Lee": "richermj123go@vip.qq.com"
+  },
+  "platforms": {
+    "ios": "9.0"
+  },
+  "source": {
+    "git": "https://github.com/CoderMJLee/MJRefresh.git",
+    "tag": "3.6.1"
+  },
+  "source_files": "MJRefresh/**/*.{h,m}",
+  "resources": "MJRefresh/MJRefresh.bundle",
+  "requires_arc": true
+}
+```
+
+更改后的包变成
+
+```
+{
+  "name": "MJRefresh",
+  "version": "3.6.1",
+  "summary": "An easy way to use pull-to-refresh",
+  "homepage": "https://github.com.cnpmjs.org/CoderMJLee/MJRefresh",
+  "license": "MIT",
+  "authors": {
+    "MJ Lee": "richermj123go@vip.qq.com"
+  },
+  "platforms": {
+    "ios": "9.0"
+  },
+  "source": {
+    "git": "https://github.com.cnpmjs.org/CoderMJLee/MJRefresh.git",
+    "tag": "3.6.1"
+  },
+  "source_files": "MJRefresh/**/*.{h,m}",
+  "resources": "MJRefresh/MJRefresh.bundle",
+  "requires_arc": true
+}
+```
+
+`github.com` 变成 `github.com.cnpmjs.org`
