==> 配置vue3框架

取名:Online PDF Book System

遇到的报错:

第一报错:

npm ERR! code CERT_HAS_EXPIRED npm ERR! errno CERT_HAS_EXPIRED npm ERR! request to https://registry.npm.taobao.org/create-vue failed, reason: certificate has expired npm ERR! A complete log of this run can be found in: C:\Users\后面个人信息省略.

解决方法是将指向淘宝的镜像,转移到官方

也就是registry属性

采用命令行:

更新 npm 配置：
确认你的 npm 配置是否仍然指向淘宝的镜像。你可以使用以下命令来查看当前的 npm 配置：

bash复制代码npm config list

如果 registry 字段指向淘宝的镜像，你可以考虑切换到官方的 npm 镜像。使用以下命令将 npm 仓库地址切换回官方地址：

npm config delete registry  
npm config set registry https://registry.npmjs.org/
