请问要在已经安装webpack项目中使用webpack，还需要做什么配置才能使用呢？

你按照项目里的readme去做就可以开始开发了啊,不用操心如何配置webpack,这也是你使用框架的意义

另外,如果你强行要修改webpack的配置的话,可以看package.json内容

{
  // ...
  "script": {
    // ...
    "start": "ts-node ./.erb/scripts/check-port-in-use.js && npm run start:renderer",
    "start:renderer": "cross-env NODE_ENV=development TS_NODE_TRANSPILE_ONLY=true webpack serve --config ./.erb/configs/webpack.config.renderer.dev.ts",
  }
}

执行npm run start的时候,会去执行npm run start:renderer,在npm run start:renderer里有指定一个./.erb/configs/webpack.config.renderer.dev.ts的webpack配置文件,你要改webpack配置的话,应该可以通过改这个文件来实现.

以下为项目readme的摘录
