Answer 1

package.json中缺少express。此外，webpack和webpack-dev-server是devDependencies，Heroku可能没有安装。

运行

npm i --save express webpack webpack-dev-server

然后提交并推送您的package.json和package-lock.json并重新部署。

如果运行后webpack和webpack-dev-server不在dependencies下，而是在package.json中的devDependencies，则运行npm uninstall webpack webpack-dev-server，然后再次运行该命令。
