sever log 如下

问题已经解决：原因是 nodejs 的安装路径有空格，不能放在 C:\Program Files，C:\Program Files (x86) 下面。否则出现如上莫名奇妙的错误。

这两天学习折腾 macaca，把目前遇到的坑和解决办法总结一下：
No1,nodejs 的安装路径不能有空格，SDK 的安装目录也是不能有空格的，原因不明，希望 macaca 团队看看解决一下。
No2,macaca.webdriver.client 这个 2.0.1jar 包下载不下来，原因是 maven 私服镜像配置问题。参考
No3,macaca-chrome 驱动,IOS 驱动等安装失败，删除临时文件夹 C:\Users\你的用户\AppData\Local\Temp 夹下 npm 开头的文件夹，重新执行命令就好了小马的 macaca 入门指引合集**
No4,Genymotion 模拟器安装 app 失败，Failure [INSTALL_FAILED_CPU_ABI_INCOMPATIBLE]。你可能需要安装 Genymotion-ARM-Translation_v1.1.zip
