提问于 2018-02-11 08:22:14
我正在尝试在Node项目上部署React，但遇到了一些问题，我不确定原因。以下是从日志中提取的一些信息：
2018-02-11T00:12:22.875338+00:00 app[web.1]: > dmdb@1.0.0 start /app
2018-02-11T00:12:22.875340+00:00 app[web.1]: > node server.js
2018-02-11T00:12:22.875341+00:00 app[web.1]:
2018-02-11T00:12:23.315310+00:00 heroku[web.1]: State changed from starting to crashed
2018-02-11T00:12:23.299113+00:00 heroku[web.1]: Process exited with status 1
2018-02-11T00:13:23.976931+00:00 heroku[router]: at=error code=H10 desc="App crashed" method=GET path="/" host=dmdb1.herokuapp.com request_id=8d37e10b-6999-4a2f-82bb-f3e724bf1c4e fwd="108.14.98.161" dyno= connect= service= status=503 bytes= protocol=https根据日志显示的内容，我的package.json文件中的启动脚本似乎有问题，但我不确定原因，因为我已经在成功部署的另一个项目中使用了类似的脚本。我对此做了一些研究，我相信我的Server.js文件已经配置好了，端口也设置好了，我删除了设备依赖项并确认它可以在本地工作，但没有部署，而且我已经在vars中设置了我的SECRET_KEY，因为它已经设置了身份验证。下面是我如何设置我的端口，以及我的package.json文件在后端的样子。如果有人能提供一些见解，我将不胜感激。如果有任何其他信息我可以提供，请让我知道，我会尽快做到这一点。
来自Server.js的端口：
//app listening on port 1337
const PORT = process.env.PORT || 1337;
app.listen(PORT, () => {
console.log(`LISTENING ON PORT ${PORT}`)
})后台更新Package.json：

}提前感谢！

使用NPM而不是Yarn重建应用程序，部署没有问题，现在运行良好。谢谢你的帮助！
