补充：直接在 REPL 中执行也是报错，确定是回复中说的 devtool 问题？

> const wd = require('wd');
TypeError: Identifier 'wd' has already been declared

    at REPLServer.Interface._line (readline.js:550:8)
    at REPLServer.Interface._ttyWrite (readline.js:827:14)

MAC 安装完毕 devtool 后，启动 devtool,

cd macaca-ios-test-sample
devtool

然后界面中输入第一行指令就出错，devtool 中指令：

const wd = require('wd');

报错内容为：

module.js:442 Uncaught Error: Cannot find module 'wd'(…)

还请问下是什么原因？我看截图是 top frame,装好后只能选 top，不知道是否和这个有关

在安装完 macaca android 版本并成功运行用例的情况下，使用指令'npm i app-inspector -g'安装报错，提示如下。设备为 win 10 32 位：

#8 楼 @anikikun 搞个，重试一两次一般都能搞上去，或者使用 npm update -g appium，我都是开着升级，快得很。

大神，fir.im 又无法登陆了，直接报 Internal Server Error，请尽快修复。

必须支持，313077271 期待中

大侠，东西很棒！但有个问题，长时间运行后，整个 mac 都变得好卡，这块能否在最新的版本中解决下？

#123 楼 @vigossjjj 首先感谢楼主的工作！对于参数-t 不是太明白，试了几次，当不指定-t 时，每次执行，从开始到结束一般也就 40s,指定-t 500，发现也是 40s 左右旧结束了，请指点
