无法运行包安装并使用 npm 运行为应用程序提供服务答案

【问题标题】：Cannot run package installation and run serve the application with npm无法运行包安装并使用 npm 运行为应用程序提供服务

【问题描述】：

我正在尝试运行我找到的这个示例。这是一个后端使用 .netcore，前端使用 Vuejs 的解决方案。我想启动 Vuejs 应用程序，只需运行 npm run serve 得到这个错误：

PS C:\Users\xxx\Downloads\VueApp> npm run serve

> vue-argon-dashboard@0.1.0 serve
> vue-cli-service serve

'vue-cli-service' is not recognized as an internal or external command,
operable program or batch file.

然后当我尝试运行npm i。我得到以下输出：

npm ERR! code ERESOLVE
npm ERR! ERESOLVE unable to resolve dependency tree
npm ERR!
npm ERR! While resolving: vue-argon-dashboard@0.1.0
npm ERR! Found: eslint@7.32.0

这是 package.json：

【问题讨论】：

标签： vue.js npm-start yarn-lock.json

【解决方案1】：

尝试删除 node_modules 文件夹，然后从 cmd 运行 npm i。

【讨论】：

我没有任何 node_modules 文件夹。

【解决方案2】：

项目根目录被锁定。我删除它并运行 npm i --force。不幸的是，它得到了更多其他不同的错误
