1.检查appium环境报错
2. 原因
appium不兼容最新的mac10.12版本。由于10.12是最新mac版本，appium当前版本并未提供支持。
3. 解决方法
命令行输入：grep -rl "Could not detect Mac OS X Version from sw_vers output:" /Applications/Appium.app/
Terminal will show : /Applications/Appium.app//Contents/Resources/node_modules/appium/node_modules/appium-support/build/lib/system.js /Applications/Appium.app//Contents/Resources/node_modules/appium/node_modules/appium-support/lib/system.js /Applications/Appium.app//Contents/Resources/node_modules/appium-support/build/lib/system.js /Applications/Appium.app//Contents/Resources/node_modules/appium-support/lib/system.js
使用命令vim编辑上述每一个输出。
