Node.js Heroku网站：npm错误！缺少脚本：开始

Heroku web正在抛出错误：

npm ERR！缺少脚本：开始

但是，当我在本地运行它时：

heroku local web

。 项目已成功构建

我已将我的package.json中的启动脚本设置为：

"scripts": {
    "start": "node server"
  }

根据文档，如果我没有指定Procfile，默认情况下它应该是

npm start

但是，我也尝试添加Procfile：

文件内容

web: npm start

它抛出同样的错误

日志输出：

我有三个相同的js名称以及我的主js文件，它对我有效。

在package.json中。

“main”：“app.js”，

我遇到了同样的问题，我的服务器在app.js文件上，我更改了package.json文件，如下所示：
