Windows搭建Nodejs【全网最详细】

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
