最近再Server 2012 + IIS 8 中配置NodeJS 运行环境，具体配置过程就不细说了(随便搜搜一堆)，安装完nodejs 和 iisnode 之后，出现一个报错，如下：

The iisnode module is unable to start the node.exe process. Make sure the node.exe executable is available at the location specified in the system.webServer/iisnode/@nodeProcessCommandLine element of web.config. By default node.exe is expected in one of the directories listed in the PATH environment variable

google 了半天，刚开始以为是x86NodeJS安装路径的问题，后来倒腾半天始终不对，后来找到篇文章 https://admin-ahead.com/forum/websitepanel/node-js-error!/

解决方法：在web.config 》system.webServer 节点加上：

<iisnode watchedFiles="*.js;node_modules\*;routes\*.js;views\*.jade"  nodeProcessCommandLine="C:\Program Files\node.exe"/>

问题解决，我鸟个去，希望能帮助到后面遇到此问题的童靴，我的web.config 文件如下，供参考：

<configuration>    <system.webServer>        <handlers>                <remove name="nodejs" />            <!-- indicates that the server.js file is a node.js application to be handled by the iisnode module -->            <add name="iisnode" path="server.js" verb="*" modules="iisnode" />        </handlers>        <iisnode watchedFiles="*.js;node_modules\*;routes\*.js;views\*.jade"  nodeProcessCommandLine="C:\Program Files\node.exe"/>    </system.webServer></configuration>
