运行环境

操作系统：win7 旗舰版

nodejs：v0.10.18

npm：1.3.8

我是用 git 把 github 上面的 appium clone 下来的，然后放到 nodejs 的 node_modoules 下面

我是想运行 sample-code\examples\node\local-android-wd-chrome.js,根据提示安装了
npm install wd
npm install colors
npm install chai
npm install chai-as-promised

下面是报错提示
C:\Program Files\nodejs\node_modules\appiums\sample-code\examples\node>node loca
l-android-wd-chrome.js
{ [Error: The environment you requested was unavailable.]
data: '{\n "status": 33,\n "value": {\n "message": "A new session could n
ot be created. (Original error: Could not find chromedriver, is it on PATH?)",\n
"origValue": "Could not find chromedriver, is it on PATH?"\n },\n "session
Id": null\n}' }

是说没有安装 chromedriver 或者没有价值 PATH 里面，我就在 google 上面下载这个驱动：
wget http://chromedriver.storage.googleapis.com/2.8/chromedriver_win32.zip

解压好，把 chromedriver 放在下面的目录下面，
D:\Program Files\adt-bundle20130522\drivers

然后在高级系统设置 -> 环境变量 ->系统变量 里面编辑 PATH，在最后面加上;D:\Program Files\adt-bundle20130522\drivers

重新打开 cmd，找到运行 local-android-wd-chrome.js 的目录，node local-android-wd-chrome.js，还是提示说没有找到 chromedriver

C:\Program Files\nodejs\node_modules\appiums\sample-code\examples\node>node loca
l-android-wd-chrome.js
{ [Error: The environment you requested was unavailable.]
data: '{\n "status": 33,\n "value": {\n "message": "A new session could n

"origValue": "Could not find chromedriver, is it on PATH?"\n },\n "session
Id": null\n}' }
