node.js - 无法启动 webpack-dev-server - 找不到模块

Question

(我正在尝试关注 this tutorial )

当我运行 npm start 时，出现以下错误:

PS C:\Users\user\Desktop\Projects\Websites\project\project> npm start 
> PROJECT@0.0.0 start C:\Users\user\Desktop\Projects\Websites\project\project
> webpack-dev-server --config webpack.config.js --open

'find_dp0' is not recognized as an internal or external command,
operable program or batch file.
internal/modules/cjs/loader.js:775
    throw err;
    ^

Error: Cannot find module 'C:\webpack-dev-server\bin\webpack-dev-server.js'
    at Function.Module._resolveFilename (internal/modules/cjs/loader.js:772:15)
    at Function.Module._load (internal/modules/cjs/loader.js:677:27)
    at Function.Module.runMain (internal/modules/cjs/loader.js:999:10)
    at internal/main/run_main_module.js:17:11 {
  code: 'MODULE_NOT_FOUND',
  requireStack: []
}

我认为主要问题是它正在我的 C:/ 驱动器中寻找 webpack-dev-server 模块，因为错误是:

Error: Cannot find module 'C:\webpack-dev-server\bin\webpack-dev-server.js'

为什么它会在那里寻找模块而不是在本地 node_modules 文件夹中？这至少是我认为导致问题的原因，但也许是其他原因？

我无法在其他任何地方在线找到同样的错误(它在用户 C:/ 驱动器中查找)。我在 Visual Studio Community 2019 工作。非常感谢任何帮助!

"start": "webpack serve --config webpack.config.js --open" 

将 package.json 的开头更改为上面的这个。我希望它会起作用
