前言
之前的一篇文章介绍了python+appium的简单安卓UI测试，之前一直是用android6.0机器测试的，今天换了android7.0，突然发现appium版本太低了，所以升级appium1.6，中间发生了不少坑，这边记录一下
排坑一
环境要求：
- node最新版本
按照网上搜的方法：
1.命令行中输入：npm uninstall -g appium
2.命令行输入：npm cache clean
3.命令行输入：npm install -g appium
cmd下输入
npm install -g appium
安装失败，日志如下：

至此，appium1.6.4安装成功
检查
输入：
appium
appium -v
appium.png
说明安装成功
排坑二
由于脚本中使用的命令，启动appium服务，运行命令
start appium :p 4754 bp 4721 device:WTKGY17811000030
启动服务失败，这边忘记截图了。
解决方案
node版本降级
卸载最新node，重新安装老版本node，问题解决
总结
总结起来就是一句话：
安装时需要node最新版本，脚本中命令行启动appium服务，需要node老版本
