找不到模块 - 找不到 DevDependency 模块

Question

我使用 npm install 安装了 ndb 和 Parcel-bundler。

npm 安装ndb --save-dev npm install Parcel-bundler --save-dev

这是我的 package.json 文件中的内容

{
  "name": "natours",
  "version": "1.0.0",
  "description": "Learning node, express, and mongoDB.  ",
  "main": "app.js",
  "scripts": {

    "debug": "ndb server.js",

    "build:js": "parcel watch ./public/js/index.js --out-dir ./public/js --out-file bundle.js"
  },

    "mongoose": "^7.5.2",
    "morgan": "^1.10.0",
    "nodemailer": "^6.9.5",
    "pug": "^3.0.2",
    "slugify": "^1.6.6",
    "validator": "^13.11.0",
    "xss-clean": "^0.1.4"
  },
  "devDependencies": {
    "ndb": "^1.1.5",
    "nodemon": "^3.0.1",
    "parcel-bundler": "^1.12.5"
  }
}

这是我遇到的错误。

可以找到来自常规依赖项的模块，例如 cryptjs，但由于某种原因找不到 ndb 和 Parcel-bundler。请帮忙。

您需要先安装

parcel

才可以使用。

$ npm i -D parcel
# OR
$ npm install --save-dev parcel
