Appium 连手机失败Error: Android bootstrap socket crashed: Error: getaddrinfo ENOTFOUND localhost undefined:4724

问题：Appium执行，连接手机报下面的错误

Error: Android bootstrap socket crashed: Error: getaddrinfo ENOTFOUND localhost undefined:4724

    at Socket.<anonymous> (lib/bootstrap.js:87:21)

    at emitOne (events.js:90:13)

    at Socket.emit (events.js:182:7)

    at connectErrorNT (net.js:994:8)

    at _combinedTickCallback (internal/process/next_tick.js:74:11)

    at process._tickCallback (internal/process/next_tick.js:98:9)

 

解决方法：

在hosts文件中增加【127.0.0.1 localhost】

 

（mac和linux中hosts文件目录：/etc/hosts）
