一、appium配置
1 . AppStore下载Xcode直接安装即可；
2 .下载Android SDK，测试Android App需要。
下载地址：https://developer.android.com/studio/index.html#downloads
选择：android-sdk_r24.4.1-macosx.zip（写本文时的最新版）如图：
解压缩到任意位置,比如/usr/local/android-sdk-macosx，
运行/usr/local/android-sdk-macosx/tools/android，即可启动Android SDK Manager，如图：
保持默认的选项即可，点击Install 23 packages…。进入到下图：
Accept License。然后Install就可以了。这个过程根据网速不同，可能需要10-20分钟，耐心等待。
3.设置Android环境变量：
方法 1：点击桌面空白位置然后使用快捷键shift+cmd+G，输入~/.bash_profile，找到.bash_profile文件，打开后在该文件中添加：
export JAVA_HOME=$(/usr/libexec/java_home)
export ANDROID_HOME=/usr/local/android-sdk-macosx
终端执行 source ~/.bash_profile 使环境变量生效。
方法 2：终端输入：
vi .bash_profile
按 i 键进入bash_profile文件编辑模式，完成之后esc键退出编辑，:wq结束。
同样执行 source ~/.bash_profile 使环境变量生效。
至此，为了安装Appium所需要的Mac平台已经配置完毕了。接下来开始安装Appium。
二、Appium安装
Appium官网下载：https://bitbucket.org/appium/appium.app/downloads/
直接安装即可。
appium doctor用来appium的是否成功安装，即点击下图按钮：
终端输出信息像下面这样全是对号，则表示环境安装成功了。

注：Android设置环境变量遇到的问题：
在.bash_profile文件中配置的环境变量路径都没有问题，但是使用appium-doctor检查后一直是:

info AppiumDoctor
排查原因：
1.打开.bash_profile文件，输入 echo hello from bash_profile!
2.打开Mac自带的终端Terminal(不是iTerm2)，发现并没有输出我刚刚在.bash_profile中输入的那句Hello from bash_profile!，所以可以判定打开终端时并没有加载.bash_profile文件读取到ANDROID_PATH和JAVA_PATH。
解决方法：
1.打开Terminal，终端->偏好设置，发现目前的设置如图所示：
修改之后如下图即可(即 使用bash shell去载入.bash_profile文件, Linux使用Bash作为默认Shell):
验证一下，再次点击Appium界面的appium-doctor按钮，终端显示如图：
打印出刚刚在.bash_profile中输入的Hello from bash_profile!
并且Android环境配置成功！
上面的这种修改方式并没有更改此时默认的shell,终端输入：
echo $SHELL
输出如下：
/bin/zsh
发现使用的shell默认还是zsh,这样在iTerm2中可以继续使用zsh.
下面第二种修改方式会更改默认使用的shell:
1.Mac自带的Terminal的偏好设置不做更改，还是如下图：
2 . 除了默认的Bash以外的Shell，查看一下系统上安装了哪些Shell。系统将安装的Shell程序列表放在/etc/shells文件中，终端输入以下命令行查看该文件获取Shell列表：
cat /etc/shells
终端输出：
# List of acceptable shells for chpass(1).
# Ftpd will not allow users to connect who are not using
# one of these shells.
/bin/bash
/bin/csh
/bin/ksh
/bin/sh
/bin/tcsh
/bin/zsh
（/bin/zsh即zsh的安装目录）
3.修改默认shell为bash
chsh -s /bin/bash
4.点击appium-doctor检验：
