multer可能出现的问题？错误:Router.use()需要回调

Question

使用yeoman angular-fullstack构建一个站点在本地工作很好,但是当我部署并使用dist/release版本时,它在我的服务器上给了我这个有趣的错误.

Error: Router.use() requires callback functions but got a [object Object]
at Function.proto.use (/home/bitnami/htdocs/dist/node_modules/express/lib/router/index.js:327:11)
at Object.<anonymous> (/home/bitnami/htdocs/dist/server/api/save/index.js:10:8)

at module.exports (/home/bitnami/htdocs/dist/server/routes.js:13:25)

它接近它在这条线上失败了

router.use(multer({ dest: './public/uploads/'}));

虽然它在当地工作完全没问题？让我有点难过.不知道它是否与缪尔有关？我安装了节点模块.思考？

最新版本multer更改了API.如果你看一下例子,你会发现你现在必须做的事情如下:

var upload = multer({ dest: './public/uploads/'});

// ...

router.use(upload.single('foofield'));

或者upload.array()或upload.fields().
