1、下载

方式一：公众号获取

关注【I am Walker】，回复”nodejs“即可

方式二：官网下载

https://nodejs.org/en/download/

2、安装

修改一下安装的目录，或者默认也ok
然后就一直点next 下一步就ok了

3、测试是否安装成功

打开命令行 win+R->输入CMD
然后输入npm -v查看npm的版本，nodejs自带npm

4、修改cache和global的路径

在nodejs下面创建两个文件夹
node_cache和node_global

然后在命令行中执行指令，注意将node_global和node_cache修改成自己的路径
npm config set prefix D:\walker\env\nodejs\node_global
npm config set cache D:\walker\env\nodejs\node_cache

例如我的

然后查看一下是否配置成功
npm config get prefix
npm config get cache

5、环境配置

“我的电脑”-右键-“属性”-“高级系统设置”-“高级”-“环境变量”

1、添加NODE_PATH

“新建“
变量名：NODE_PATH
变量值：node_modules的路径![image.png](https://img-blog.csdnimg.cn/img_convert/941ae2c0096d6cb919903f80fa18ce3a.png#clientId=ufd03c04a-d4d9-4&crop=0&crop=0&crop=1&crop=1&from=paste&height=179&id=u68cee658&margin=[object Object]&name=image.png&originHeight=179&originWidth=702&originalType=binary&ratio=1&rotation=0&showTitle=false&size=19194&status=done&style=none&taskId=u30f67bc3-667e-44bb-8f23-86908541026&title=&width=702)
