解決Appium報錯read ECONNRESET

報錯信息如下：

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

問題原因：該錯誤為端口掃描問題，如果某個端口無法通信（可能被防火牆過濾了也可能被其它軟件占用），就會報這種錯誤。

解決辦法：卸載本地環境殺毒軟件，重啟電腦。
