\r\n主要的原因是下面两段代码：\r\n第一中写法：\r\n

\r\napp.get('/', function(req, res){\r\n    res.sendfile(__dirname + '/index.html');\r\n});\r\n

\r\n第二种写法：\r\n

\r\napp.get('/', function(req, res){\r\n\tres.sendfile('/index.html', {root: __dirname});\r\n});\r\n

\r\n用第一段代码会出错，改成第二种写法就没问题了。\r\n这是怎么个情况呢，求真相。。。","title","小错误：TypeError: Arguments to path.join must be strings, 求真相","last_reply_at","2014-05-10 16:41:21.425","good","top",11,"visit_count",7040,"2014-05-10 06:58:51.835","author",{"_13":14,"_22":23}]
