说明
NPM是随同NodeJS一起安装的包管理工具，能解决NodeJS代码部署上的很多问题，本文主要对NPM的基本使用、依赖包的升级方法等进行简要的记录说明。
常用命令
- 依赖包安装：
npm install xxx
- 全局安装依赖包:
npm install -g xxxx
- 查看缓存路径:
npm config get cache
- 修改缓存路径:
npm config set cache /path/a/b
- 查看依赖包是否已经过期:
npm outdated
- 指定环境变量启动:
npx cross-env NODE_OPTIONS="--trace-warnings" hexo s
依赖包升级
- 安装工具：
npm install -g npm-check-updates
- 通过
ncu工具再次检查是否有依赖包需要进行升级操作: ncu
