Mac下安装及配置Appium环境

我是小白，自己研究appium好几周了。

一开始按照同事这篇文章设置Mac下的环境，http://www.cnblogs.com/tangdongchu/p/4432808.html

因为当时在命令行端没能用npm install安装成功，而只是安装了appium的dmg程序，平时用appium.app端也够了。但是后续因为需求http://testerhome.com/topics/2616，发现得用命令行调用appium，所以今天再努力一把，用命令行把appium安装成功。

今天参考了这几篇文章的步骤安装appium

首先，官方网站上给出的安装的教程，颇为简单：

> brew install node      # get node.js
> npm install -g appium  # get appium
> npm install wd         # get appium client
> appium &               # start appium
> node your-appium-test.js

但，只是看着简单而已，自己搭建的过程中可能会遇到各种问题

brew install node 想要生效首先必须先安装homebrew才行，所以第一步应当是检查自己是否已经安装homebrew
在终端中输入brew -v 如果出现版本信息则说明已经安装

➜ ~ brew -v
Homebrew 0.9.5

在终端输入brew install node 命令安装node.js 安装完成后在终端输入node -v命令检查是否安装成功，出现版本信息说明安装成功

➜ ~ node -v
v0.10.35

在终端输入npm uninstall appium -g，因为被墙，下不下来，即使连接VPN也各种下不下来~

使用其他人推荐的这个镜像，还是下不下来，花了好长时间，还是不成功，真的好郁闷

npm --registry http://registry.cnpmjs.org install -g appium

后来，找到这篇文章http://testerhome.com/topics/1827

推荐taobao的npm镜像，下载速度较快，墙裂推荐使用！

npm --registry http://registry.npm.taobao.org install -g appium

npm 安装好 Appium 好之后，可以运行下 appium-doctor，检查自己的各种环境变量是否配置成功

➜  ~  appium-doctor

npm install wd 这个也是下载不了，目前不知道是什么东东，不影响就先不管了

在终端输入 appium& 即可启动appium，在这里多说一句，直接输入 appium 也可以启动appium，只是加个&可以显示appium的pid，而不加则不会显示

➜  ~  appium&
[2] 3679
➜  ~  warn: Appium support for versions of node < 0.12 has been deprecated and will be removed in a future version. Please upgrade!
info: Welcome to Appium v1.4.3 (REV a357c7fa73222315dd85c3d2dd8334767cca1b0d)
info: Appium REST http interface listener started on 0.0.0.0:4723
info: Console LogLevel: debug

命令行启动appium之后，如果关闭终端，隔一会你要再运行，会提示error

➜  ~  appium
warn: Appium support for versions of node < 0.12 has been deprecated and will be removed in a future version. Please upgrade!
error: Couldn't start Appium REST http interface listener. Requested port is already in use. Please make sure there's no other instance of Appium running already.

因为端口被node占用呢，可以用如下退出node

➜  ~  pkill node
[2]    3679 exit 143   appium

也可以用之前自己的笨办法

知道可以查询4723端口找到PID，然后kill -9 PID

mac&linux下查看端口被哪个进程占用

mac : lsof -i:8080

linux : neststat -anltp | grep 8080

➜  ~  lsof -i:4723
COMMAND  PID  USER   FD   TYPE             DEVICE SIZE/OFF NODE NAME
node    3679  XXXXX  12u  IPv4 0xaecf7b4424b87de7      0t0  TCP *:4723 (LISTEN)
