如我在indexhtml 内写

<%-header%> 的header还一定是ejs ,不过你可将扩展名加进去。

appset(‘view engine’, ‘html’);

appengine(‘html’,require(‘ejs’)renderFile);

创建Hello World不应该是这样子的。我看出你的意思了，你只是想写控制台下的简单程序。可是你选择的是Win32程序。那个都涉及到SDK了。

按以下步骤做，file->new->project->empty project（即选择空项目，我的是中文版，不知道英文版怎么写的，翻译过来应该是empty project吧）。

然后再生出的空工程里面，会发现Solution视图里面有header files,source files,resource files,在source files里面添加一个item。选择cpp即可开始编辑。写好后点击绿色的小箭头（或者按F5）就会给你一条龙服务。编译链接执行一次性完成。而且打印出hello world后控制台自动关闭，所以你看不到运行效果，因此要在主函数末尾return 0上一行添加system("pause");这样就能看到了。如果不想这样也行，不要点绿色小箭头，而是按Ctrl+F5就直接运行而不调试（这个在Debug菜单里也有）。

说的够详细了吧。我可都是一字一句敲进去的。

如果还有疑问。发函到lcsaintlee@gmailcom半个工作日内给你回复。

你好，两个都是设置Header的，但是如果你是使用原生node的>
