不确定为什么我会收到错误以及为什么它在启动 express.js 时没有启动

Question

My express.js is unable to start upon typing npm start and I don't understand why it's happening, here's my error log:

C:\Users\simer\Desktop\API-workshop>npm start

> api-workshop@0.0.0 start C:\Users\simer\Desktop\API-workshop
> node ./bin/www

internal/modules/cjs/loader.js:905
  throw err;
  ^

Error: Cannot find module 'http-errors'

Does anyone know what I should do?

You need to install Your package - http-errors in root project directory.

1. npm install http-errors
2. Try to run again npm start
