Appium 环境搭建 - macOS

本文没有安装 Appium Desktop，Appium Server 直接在命令行中进行即可。

1. Homebrew，macOS 包管理器： ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)" 。
2. Carthage，appium-doctor 会检查这一项： brew install carthage 。
3. node & npm，nodejs： brew install node 。
4. appium：npm install -g appium，推荐使用淘宝镜像 npm --registry http://registry.npm.taobao.org install -g appium 。
5. wd： npm --registry http://registry.npm.taobao.org install -g wd 。
6. appium-doctor： npm --registry http://registry.npm.taobao.org install -g appium-doctor 。
7. Xcode：App Store上安装时一直转圈，网上找到两种解决方案：一更改 DNS 为114.114.114.114，无效；二是去苹果开发中心下载 Xcode 安装包，一直在官网没找到/(ㄒoㄒ)/~~。发现自己 App Store中 macOS Sierra 需要更新，更新完成后重启电脑，再在 App Store 中下载 Xcode，可以了。
8. Android SDK：Android Studio 中文社区有提供独立安装包。
9. 环境变量配置：
   1. 新建 ~/.bash_profile 文件： touch ~/.bash_profile 。
   2. 在 .bash_profile 文件写入一下内容，配置环境变量。

      export ANDROID_HOME="/usr/local/bin/android-sdk"
      export JAVA_HOME=$(/usr/libexec/java_home)
      export PATH=$PATH:$JAVA_HOME/bin:$ANDROID_HOME/tools:$ANDROID_HOME/platform-tools 

   3. 执行 .bash_profile，使环境变量生效：source ~/.bash_profile 。
10. 检查配置环境
