在命令行中进入根目录，使用 npm init命令初始化项目，完成后根目录中会生成package.json文件：

Microsoft Windows [版本 6.2.9200]

C:\Users\yangyi>g:

G:\>cd xx/node/smallalbum

G:\xx\node\smallalbum>npm init
This utility will walk you through creating a package.json file.
It only covers the most common items, and tries to guess sensible defaults.

See `npm help json` for definitive documentation on these fields

save it as a dependency in the package.json file.

Press ^C at any time to quit.
