heroku - 部署到 heroku 会引发 webpack (package.json) 的问题

Question

我不断尝试寻找解决问题的方法，我发现了很多解决方案，但似乎没有一个适合我的问题。我对配置 package.json 和其他构建/配置文件夹非常不熟悉，所以我害怕我可能做错了。

基本上，当我部署到 heroku 时，我一直收到 webpack 的错误。尽管它似乎可以在 localhost 上运行，但是诸如

internal/modules/cjs/loader.js:583
    throw err;
    ^

Error: Cannot find module 'webpack/bin/extract-text-webpack-plugin'

当我部署到heroku时开始浮出水面。

我设置了我的 NPM_CONFIG_PRODUCTION=false 和 NODE_ENV=development 并没有帮助。我重新安装了 npm 的 package.json 并没有帮助。

这是我当前的 package.json
