将Node RED部署到Heroku

Question

我发现了Github repo中包含的文件，这些文件用于连接到Heroku服务器，并被我自己的包所取代。json，flow.json和app.json中的repo链接。部署后，我尝试打开应用程序，但从Heroku CLI的日志窗口收到如下错误：

您已经从package.json中删除了Node RED，因此由于它没有安装，因此不会启动。

{
"name": "node-red-project",
"description": "A Node-RED Project",
"version": "0.0.1",
"dependencies": {
"node-red-contrib-alarm": "~1.2.5",
"node-red-contrib-component-dashboard": "0.0.4",
"node-red-contrib-components": "~0.1.8",
"node-red-contrib-firebase": "~1.1.1",
"node-red-contrib-influxdb": "~0.5.1",
"node-red-contrib-mqtt-broker": "~0.2.4",
"node-red-contrib-remote": "~1.1.3",
"node-red-contrib-ttn": "~2.0.5",
"node-red-contrib-ui-svg": "~2.2.1",
"node-red-contrib-users": "~0.1.9",
"node-red-dashboard": "~2.14.0",
"node-red-node-ui-table": "~0.3.10"
}
}

如果要添加额外的节点，则需要将这些节点添加到现有package.json中的依赖项列表中，而不仅仅是替换它们。

{
"name": "nodered-heroku",
"version": "0.0.7",
"dependencies": {
"when": "3.7.8",
"nano": "8.2.2",
"feedparser":"2.2.10",
"node-red-dashboard":"2.23.3",
"redis":"3.0.2",
"node-red": "1.1.3",
"node-red-node-tail": "0.1.1",
"node-red-contrib-aedes": "0.3.6",
"node-red-contrib-blynk-ws": "1.0.3",
"node-red-node-email": "1.7.9",
"node-red-node-ui-list": "0.3.1",
"node-red-contrib-telegrambot": "8.4.0",
"node-red-contrib-alarm": "~1.2.5",
"node-red-contrib-component-dashboard": "0.0.4",
"node-red-contrib-components": "~0.1.8",
"node-red-contrib-firebase": "~1.1.1",
"node-red-contrib-influxdb": "~0.5.1",
"node-red-contrib-mqtt-broker": "~0.2.4",
"node-red-contrib-remote": "~1.1.3",
"node-red-contrib-ttn": "~2.0.5",
"node-red-contrib-ui-svg": "~2.2.1",
"node-red-contrib-users": "~0.1.9",
"node-red-node-ui-table": "~0.3.10"
}
}

我还建议你使用最新版本的Node RED(发布时为1.3.1(，因为1.1.3是非常旧的
