node.js - multer v1.3.0上傳封包500錯誤

Question

我用的express框架，試著用multer中間件做上傳，原來是最基礎的上傳，就是
var upload = multer({ dest: 'uploads/' })，但是我發現這上傳上去的檔案都是沒有後綴名的16位元隨機字串，我的要求是要規範化的檔案命名，所以我用了multer.diskStorage對檔案進行更多的操作下面是我的程式碼：
`var express = require('express');
var router = express.Router();
var multer = require('multer');

//設定儲存路徑
//var upload = multer({ dest: 'uploads/' })

/ GET home page. /
router.get('/', function(req, res, next) {
res.render('index', { title: ' Express' });
});

var storage = multer.diskStorage({

destination: function (req, file, cb) {
    cb(null, '/uploads');
},
filename: function (req, file, cb) {
    cb(null, file.fieldname+"-"+Date.now());
}

});

var upload = multer({ storage: storage });

router.post('/upload', upload.single('image')), function(req, res, next){

var image=req.file.path;
res.send('index', { title : 'Express' ,image:image});

}

module.exports = router;
`
我覺得這應該是最基本的demo了，但是就是報500錯誤，報錯如下：

POST /upload 500 16.841 ms - 1278

我看了網路上很多資料,github上也看了，感覺就是找不到原因，求大神指點迷津

Answer 1

500是伺服器錯誤，app.js第45行錯了，res.send('index', { title : 'Express' ,image:image});，你準備把文件傳到瀏覽器？

Answer 2

搞了半天，本身預設的error.jade展示不出來，因為我用了pug模板，後來改過來了，錯誤一目了然，destination設定的路徑是從硬碟根目錄開始的，例如我寫的是/uploads,那個儲存的路徑就是D://uploads，因為沒有這個資料夾，所以它一直報錯，只要把它修改一下就好了
