Nodejs开发之五: npm uninstall ,删除不需要的包加载

例如, 我们删除buffer 和ignore两个包:

1. 命令行 :

C:Program Files odejsMyBook>npm uninstall buffer
npm WARN mybook@1.0.0 No repository field.

removed 3 packages and audited 1 package in 3.909s
found 0 vulnerabilities

C:Program Files odejsMyBook>npm uninstall ignore
npm WARN mybook@1.0.0 No repository field.

removed 1 package in 2.56s
found 0 vulnerabilities

2. 删除后的文件夹:

3. 删除后的package.json和package_lock.json

{
  "name": "mybook",
  "version": "1.0.0",
  "description": "My book shelf",
  "main": "index.js",
  "scripts": {
    "test": "node app.js"
  },
  "author": "author",
  "license": "ISC",
  "dependencies": {},
  "devDependencies": {}
}

　　

{
  "name": "mybook",
  "version": "1.0.0",
  "lockfileVersion": 1
}
