2、查看 Node.js 的版本：v8.10.0。要求的版本至少为：Node v12.14。如图2
图2
PS E:\wwwroot\laravel-8-5> node -v v8.10.0
3、参考网址：https://www.jianshu.com/p/0f3fdf6c0d5f ，重新安装最新稳定版本。下载 14.18.1 LTS。安装路径与旧版本保持一致：C:/Program Files/nodejs。如图3
图3
4、再次查看 Node.js 的版本：v14.18.1。如图4
图4
PS E:\wwwroot\laravel-8-5> node -v v8.10.0 PS E:\wwwroot\laravel-8-5> npm -v 5.5.1 PS E:\wwwroot\laravel-8-5> where node PS E:\wwwroot\laravel-8-5> node -v v14.18.1 PS E:\wwwroot\laravel-8-5> npm -v 5.5.1
5、npm WARN npm npm does not support Node.js v14.18.1。参考网址：https://stackoverflow.com/questions/63196042/npm-does-not-support-node-js-v12-18-3 。进入目录：C:\Users\Administrator\AppData\Roaming\。删除 npm 和 npm-cache 文件夹。如图5

6、查看 npm 的版本：6.14.15，再次更新 npm。执行命令：npm install -g npm。升级至版本：8.1.0。如图6
图6
