我尝试了在这里找到的所有解决方案，但仍然无法在Heroku上部署该应用程序 我找到并尝试过的方法：
- updated all packages,
- heroku restart
- checked on start server.js
("scripts": {
"start": "node server.js"
}
， -用||指定的PORT -添加引擎npm和节点：
"engines": {
"node": "v10.4.0",
"npm": "6.4.1"
}
- added a sequelizerc:
var path = require ('path');
module.exports = {
'config': path.resolve('config', 'config.js')
}
仍然得到错误代码= H10 desc =“应用程序崩溃”方法= GET路径=“ /”
