解决Appium报错read ECONNRESET

报错信息如下：

error: Unhandled error: Error: read ECONNRESET
    at exports._errnoException (util.js:837:11)
    at TCP.onread (net.js:544:26) context: [POST /wd/hub/session {"desiredCapabi
lities":{"appPackage":"com.tencent.mm","appActivity":".ui.LauncherUI","recreateC
hromeDriverSessions":true,"noReset":true,"platformVersion":"4.4","unicodeKeyboar
d":"false","fastReset":"f]
info: [debug] Logcat terminated with code 0, signal null
info: [debug] UiAutomator exited

问题原因：该错误为端口扫描问题，如果某个端口无法通信（可能被防火墙过滤了也可能被其它软件占用），就会报这种错误。

解决办法：卸载本地环境杀毒软件，重启电脑。
