1.安装node.js
前往官网下载并安装工具，自定义安装路径(D:\Program Files\nodejs)
# 安装完毕在命令行输入以下命令测试是否安装成功，正确会出现版本号
npm –v
2.改变原有的环境变量
（1）我们要先配置npm的全局模块的存放路径以及cache的路径
#例如我希望将以上两个文件夹放在NodeJS的主目录下，便在NodeJs下建立”node_global”及”node_cache”两个文件夹
#输入以下命令改变npm配置
npm config set prefix “D:\Program Files\nodejs\node_global”
npm config set cache “D:\Program Files\nodejs\node_cache”
npm config get prefix #获取全局安装的默认目录
（2）在系统环境变量添加系统变量NODE_PATH,将”D:\Program Files\nodejs\node_global”设为系统环境变量PATH
# 输入路径D:\Program Files\nodejs\node_global\node_modules，此后所安装的模块都会安装到改路径下
基本命令
npm init #初始化
npm install express #本地安装
npm install exoress -g #全局安装
npm update express #更新模块
npm uninstall express #本地卸载
npm uninstall express -g #全局卸载
npm cache clean –force #清除缓存
npm install -g npm #更新npm
npm install -g npm@8.3.0 #安装npm指定版本
npm root -g #查看全局安装包的存放位置
npm ls -g #查看全局安装的包
npm info npm #查看npm的信息
npm config set registry https://registry.npm.taobao.org #设置淘宝镜像站
npm config get registry #获取npm下载地址
npm config set registry https://registry.npmjs.org #还原npm仓库
npm audit fix #包的修复 ，一般是包的更新
npm config list #查看基本配置
安装到依赖
npm i 包名 —save #–save为默认选项，意思为添加到package.json的dependencies里面
安装到开发依赖
#开发依赖指项目的开发过程中需要使用的包，像less编译为css、语法检查模块等
npm i 包名 —save–dev #–save-dev意思为添加到package.json中的devDependencies里面
安装淘宝npm（cnpm）
npm install -g cnpm –registry=https://registry.npmmirror.com
cnpm -v #查看安装版本
#注：如果报错，添加系统变量path的内容
#因为cnpm会被安装到D:\Program Files\nodejs\node_global下，而系统变量path并未包含该路径。在系统变量path下添加该路径即可正常使用cnpm
设置淘宝源：
npm config set registry http://registry.npmmirror.com
npm config get registry
npm config set registry https://registry.npmjs.org
cnpm install -g electron
cnpm install -g electron-forge
electron-forge init notepad
electron-forge start
npm start
npm run make
