之前写过一篇Appium for windows的文章，因为是 09 年的 T400，启动 Android 模拟器的时候死机三次，那就公司申请台 Macbook air 吧，15 寸的 Macbook Pro 实在太重了，也就 Mac 才能真正发挥 Appium 的功能，支持 Android 和 iOS。好了，废话不多，开始。

1. 爬墙
因为后续安装过程中可能会碰到墙的问题，所以首先得解决爬墙的问题。
我的方便，公司提供代理。

2. java
guowenxie-macbookair:~ guowenxie$ java -version
java version "1.8.0_05"
Java(TM) SE Runtime Environment (build 1.8.0_05-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.5-b02, mixed mode)

3. git
guowenxie-macbookair:~ guowenxie$ git --version
git version 1.8.5.2 (Apple Git-48)

4. ruby
guowenxie-macbookair:~ guowenxie$ ruby -v
ruby 2.0.0p451 (2014-02-24 revision 45167) [universal.x86_64-darwin13]

5. brew
guowenxie-macbookair:~ guowenxie$ brew -v
Homebrew 0.9.5

这边提下 brew 的安装，brew是 Mac OS 不可或缺的套件管理器
执行下面命令
ruby -e "$(curl -fsSL https://raw.github.com/Homebrew/homebrew/go/install)"

6. node
有了 brew 安装 node 就方便了
brew install node

7. npm
guowenxie-macbookair:~ guowenxie$ npm -v
2.0.0-alpha-5

8. Appium
现在可以开始安装 Appium

guowenxie-macbookair:~ guowenxie$ appium -v
1.2.0

9. wd
npm install wd

10. Xcode 和 Android SDK
这个不说了

11. 检查环境
Appium 提供了一个 doctor，运行 appium-doctor
guowenxie-macbookair:~ guowenxie$ appium-doctor
Running iOS Checks
✔ Xcode is installed at /Applications/Xcode.app/Contents/Developer
✖ Xcode Command Line Tools are NOT installed: Error: Command failed: No receipt for 'com.apple.pkg.CLTools_Executables' found at '/'.
Fix it? (y/n) y
Press any key to continue:
✔ Xcode Command Line Tools are installed.
✔ DevToolsSecurity is enabled.
✔ The Authorization DB is set up properly.
✔ Node binary found at /usr/local/bin/node
✔ iOS Checks were successful.
Running Android Checks
✖ ANDROID_HOME is set but does not exist on the file system at "Users/guowenxie/Documents/adt-bundle_mac-x86_64-20140702/sdk"
Appium-Doctor detected problems. Please fix and rerun Appium-Doctor.

这里可以看到我 Xcode Command Line Tools 没有安装，这个方便，Fix it?的时候输入 Y，就能自动导向安装了。
另一个是 ANDROID_HOME 的环境变量没配置好，那么我们要配置下。

12. bash_profile 文件
Mac 默认是没有这个文件的，我们自己建一个
touch .bash_profile

vi .bash_profile
打开 bash_profile 文件配置 ANDROID_HOME 和 JAVA_HOME
export ANDROID_HOME="/Users/guowenxie/Documents/adt-bundle-mac-x86_64-20140702/sdk"
export JAVA_HOME=$(/usr/libexec/java_home)

source .bash_profile
好了，再次运行 appium-doctor
guowenxie-macbookair:~ guowenxie$ appium-doctor
Running iOS Checks
✔ Xcode is installed at /Applications/Xcode.app/Contents/Developer
✔ Xcode Command Line Tools are installed.
✔ DevToolsSecurity is enabled.
✔ The Authorization DB is set up properly.
✔ Node binary found at /usr/local/bin/node
✔ iOS Checks were successful.
Running Android Checks
✔ ANDROID_HOME is set to "/Users/guowenxie/Documents/adt-bundle-mac-x86_64-20140702/sdk"
✔ JAVA_HOME is set to "/usr/libexec/java_home."
✔ ADB exists at /Users/guowenxie/Documents/adt-bundle-mac-x86_64-20140702/sdk/platform-tools/adb
✔ Android exists at /Users/guowenxie/Documents/adt-bundle-mac-x86_64-20140702/sdk/tools/android
✔ Emulator exists at /Users/guowenxie/Documents/adt-bundle-mac-x86_64-20140702/sdk/tools/emulator
✔ Android Checks were successful.
✔ All Checks were successful

到此，环境基本准备好了。

最后，如果不想通过命令行安装 Appium，也可以安装 dmg
