node.js - 如何使用 npm run serve 解决错误

Question

我是 Vue 的新手。我已经成功创建了一段时间的项目，没有任何问题。然而，今天我创建了一个新项目，当我尝试“npm run serve”时，我突然得到了三个错误。即使是服务良好的旧项目，我也无法再次为他们服务

我使用的是 Windows 7，所以节点版本是 13.14.0 这是我得到的错误： ERROR Failed to compile with 3 errors

ERROR  Failed to compile with 3 errors

These dependencies were not found:

 * C:\Users\hp\Documents\vue full learn\dojo-blog- 
  composition\node_modules\webpack-dev-server\client\index.js? 
  http://192.168.43.35:8081&sockPath=/sockjs-node in multi

    To install them, you can run: npm install --save 
    C:\Users\hp\Documents\vue full learn\dojo-blog- 
   composition\node_modules\webpack-dev- 
    server\client\index.js? 
   http://192.168.43.35:8081&sockPath=/sockjs-node 
    C:\Users\hp\Documents\vue full learn\dojo-blog- 
    composition\node_modules\webpack\hot\dev-server.js


   This relative module was not found:

  * ./src/main.js in multi (webpack)-dev-server/client? 
   http://192.168.43.35:8081&sockPath=/sockjs-node 
    (webpack)/hot/dev-server.js ./src/main.js

我检查了 webpack-dev-server 在 node-bundles 文件夹中。当我尝试按照上面的指示进行安装时，出现了更多错误：

npm ERR! code ENOLOCAL
npm ERR! Could not install from "..\..\..\Documents\vue" as it 
does not contain a package.json file.
npm ERR! A complete log of this run can be found in:

operable program or batch file.

这是 package.json

我用 npm install 得到了这个
