篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了Windows搭建Nodejs全网最详细相关的知识,希望对你有一定的参考价值。
1.下载镜像【WIN7用户看这里】
2.默认安装完毕后,创建node_global&node_cache文件夹
补充:它默认是存储在C:\\Users\\ROOT\\AppData\\Roaming的
3.修改默认环境
npm config set prefix "C:\\Program Files\\nodejs\\node_global"
npm config set cache "C:\\Program Files\\nodejs\\node_cache"
4.环境变量(NODE_PATH)
修改用户变量的npm路径C:\\Program Files\\nodejs\\node_global
5.安装全局文件
npm install webpack -g
补充:有的同学可能会报错哈

是因为当前用户没权限写入文件夹
- 解决方案一:
给一下权限就OK了
- 解决方案二:
写入完成
查看webpack版本
6.设置镜像
npm config get registry # 查看当前镜像库
npm config set registry https://registry.npm.taobao.org --global # 设置全局淘宝镜像
npm config set registry https://registry.npmjs.org/ # 切换回默认地址
npx nrm use taobao # 切换到淘宝源
npx nrm use npm # 切换到官方
- 安装cnpm
npm install -g cnpm --registry=https://registry.npmmirror.com
cnpm -v # 查看版本
npm list -g # 查看全局安装的模块
npm list vue # 查看某个模块的版本号
npm install sass-node@x.x.x # 安装提定版本包
npm update sass-node # 更新到最新版的包
npm uninstall jquery # 卸载包
7.执行报错
Error while executing: npm ERR! D:\\Program Files\\Git\\cmd\\git.EXE ls-remote -h -t git://github.com/ad
npm config set registry https://registry.npmmirror.com
# 使用淘宝镜像安装即可
npm install --registry=https://registry.npm.taobao.org
