Angular 7 应用程序部署到 Heroku - 构建失败，应用程序错误

Question

我正在尝试将我的 Angular 应用程序部署到 Heroku。我在这方面的经验有限并且遇到了错误。我对 stackoverflow 的搜索让我尝试了不同的配置，但每次都会出错。我得到的最接近的是当我没有在脚本中包含“postinstall”时，在这种情况下构建成功，但我仍然收到相同的代码 H10 应用程序错误。

我尝试过“postinstall:ng build --aot --prod”、“heroku-postbuild”:“ng build --aot --prod”和 ng build --aot --prod”，但没有区别在于，由于这一行，每次构建都会失败。

这是我的 package.json

  },

    "npm": "6.4.1"
  }
}

我的server.js

const express = require('express');
const path = require('path');

const app = express();

// Serve only the static files form the dist directory
app.use(express.static(__dirname,  '/dist/hockey-app'));

app.get('*', function(req,res) { 
    res.sendFile(path.join(__dirname, '/dist/hockey-app/index.html'));
});

// Start the app by listening on the default Heroku port
app.listen(process.env.PORT || 8080);

感谢任何帮助。谢谢。

编辑:构建成功并部署，但继续出现应用程序错误。 Heroku 日志:

尝试移动

"@angular/cli": "~6.2.5",
"@angular/compiler-cli": "^6.1.0"

从devDependencies到依赖项...
