如何修复节点服务器错误 npm ERR？ 代码 ELIFECYCLE npm 错误！ 错误1？

Question

npm ERR. code ELIFECYCLE npm ERR. errno 1 npm ERR: node-express@1.0.0 start: node server npm ERR. Exit status 1 npm ERR. npm ERR. Failed at the node-express@1.0.0 start script. npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

I haven't had any issues until I had to add routes for partners and promotions in my project. I don't know how to debug this type of error in order to make the needed changes. What can possibly be the issue? I'm still learning. Here is a link: https://github.com/TanishaV842/node-express/tree/master/routes

Answer 1

One of the issues you have is that it looks like you're including code for your routers in multiple places:

// server.js

app.use("/campsites", campsiteRouter);
app.use("/partners", partnerRouter);
app.use("/promotions", promotionRouter);

campsiteRouter.route("/campsites").all(...);
partnerRouter.route("/partners").all(...);
promotionsRouter.route("/promotions").all(...);

There's no need to do that, just do app.use("/campsites", campsiteRouter); and get rid of the router code inside server.js .

---

Second, the code inside of your routers is incorrect in two ways:

// these are two different routes, so create a separate
// route for `/campsites/:campsiteId`,
// additionally, you don't want to do `/campsites/:campsiteId` 
// because you specified the `/campsite` route/portion inside of 
// your `server.js` file when you did 
// `app.use("/campsites", campsiteRouter)`, so only use `/:campsiteId`

// WRONG
campsiteRouter
  .route("/campsites")
  .all(...)
  .get("/campsites/:campsiteId", ...)

// CORRECT
campsiteRouter
  .route("/:campsiteId")
  .all(...)
  .get((req, res) => {
    console.log(req.params.campsiteId);
  })
  .post(...);

Here's your fixed code:

Hope this helps.

Answer 2

It looks like you're mixing up regular router.get() with router.route().get() method parameters.

Because you're using the router.route() method, your:

.get() .post() .delete()

call can't pass in a string and a callback. They only except a callback function.

To fix,

change all of the router.route(...).get('<path>', (req, res) => {})

to something like:

router.route(...).get((req, res) => {})

No path parameter.
