Possible issue with multer? Error: Router.use() requires callback

Question

使用 yeoman angular-fullstack 构建站点在本地运行良好，但是当我部署和使用 dist/release 版本时，它在我的服务器上出现了这个有趣的错误。

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.require (module.js:365:17)
at require (module.js:384:17)
at module.exports (/home/bitnami/htdocs/dist/server/routes.js:13:25)

它似乎在这条线上失败了

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

尽管它在本地完全正常工作？让我有点难过。想知道它是否与multer有关？我安装了节点模块。想法？

multer 的最新版本更改了 API。如果您查看 examples，您会发现您现在必须执行以下操作：

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

// ...

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

或upload.array()或upload.fields()。
