node.js body-parser 为什么会报错 bodyParser.raw is not a function?

Question

很简单的一段代码，想要设置raw的entity大小，因为上传图片导致node request entity too large

修改：

app.use(bodyParser.json({limit: "50mb"}));
app.use(bodyParser.raw({limit: "50mb"}));//这里出错了，bodyParser.raw is not a function?
app.use(bodyParser.urlencoded({limit: "50mb", extended: true, parameterLimit:50000}));
