1. 执行 npm install ，

C:\Program Files\nodejs\MyBook>npm install
npm notice created a lockfile as package-lock.json. You should commit this file.

npm WARN mybook@1.0.0 No repository field.

up to date in 2.282s
found 0 vulnerabilities

2. 依赖包被安装到了 node_modules . 同时生成package-lock.json文件.

package-lock.jsaon 文件内容:

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

3. 安装项目需要的buffer包 npm install buffer 和 ignore

C:\Program Files\nodejs\MyBook>npm install buffer

npm WARN mybook@1.0.0 No repository field.

+ buffer@5.6.0
added 3 packages from 4 contributors and audited 3 packages in 5.157s
found 0 vulnerabilities

C:\Program Files\nodejs\MyBook>npm install ignore
npm WARN mybook@1.0.0 No repository field.

+ ignore@5.1.8
added 1 package from 1 contributor and audited 4 packages in 1.695s
found 0 vulnerabilities

自动生成了node_modules.
