【问题描述】:
我的 Heroku 应用程序崩溃了,我相信它甚至还没有进入 Procfile。我遇到了和这里一样的问题:
Cannot execute Node.js app on Heroku successfully (crashes each time)
唯一的区别是我的 package.json 文件包含了 Express
package.json
{
"name": "weathersocket",
"version": "0.0.1",
"description": "text based weather",
"main": "weather.js",
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1"
},
"repository": {
"type": "git",
"url": "https://github.com/agreen757/weathersocket.github.io"
},
"keywords": [
"demo",
"heroku",
"weather"
],
"author": "Adrian Green",
"license": "MIT",
"bugs": {
"url": "https://github.com/agreen757/weathersocket.github.io/issues"
},
"homepage": "https://github.com/agreen757/weathersocket.github.io",
"dependencies": {
"body-parser": "^1.6.6",
"consolidate": "^0.10.0",
"cookie-parser": "^1.3.2",
"express": "^4.8.6",
"mongodb": "^1.4.9",
"socket.io": "^1.0.6",
"swig": "^1.4.2"
}
}
我已尝试在本地使用工头实用程序,一切正常。
我的主 weather.js 文件包含:
server.listen(4000);
console.log("Express server started on 4000");
任何帮助将不胜感激。

好吧,这可能不是答案,但我在 heroku 上部署的 golang 应用程序也遇到了类似的问题。该应用程序崩溃了,因为我像您一样手动设置了端口。尝试将
server.listen(4000)更改为server.listen(process.env.PORT)并让heroku 决定使用哪个端口。如果它解决了问题,您可以使用 heroku configs 设置端口:heroku config:set PORT=4000. -
您还可以使用一些日志更新您的问题。
heroku logs -
我刚刚尝试部署您的应用程序。我使用了来自您的 github 链接的资源,从您的帖子中复制了
package.json并创建了一个 Procfileweb: node weather.js。尽管我遇到了另一个问题并使用[此解决方案]解决了它。(stackoverflow.com/questions/23987571/…)。应用程序现在在 heroku 上运行良好。您是否使用相同的来源?你的 Procfile 里面有什么? -
我认为 Function.Module._resolveFilename (module.js:338:15) 的错误是因为找不到模块,因此让我认为您在依赖项中缺少一些节点包,不能是吗?我看到了 socket.io,但表现得好像没有安装
