Question

我正在使用Openshift来创建我的节点红应用程序。我想将我的节点存储在Openshift环境变量的用户目录中Environment: DEV_MODE=false NODE_ENV=production DEBUG_PORT=5858 Launching via npm... npm info it worked if it ends with ok npm info using npm@2.15.1 npm info using node@v4.6.2 npm info prestart node-red-app@ npm info start node-red-app@ > node-red-app@ start /opt/app-root/src > node app.js Potentially unhandled rejection [1] Error: Property 'userDir' is read-only但是当我构建并运行我的应用程序时，我看到来自Openshift部署日志的错误：

var http = require('http');
var express = require("express");
var RED = require("node-red");


// Create an Express app
var app = express();

// Add a simple route for static content served from 'public'
app.use("/",express.static("public"));

// Create a server
var server = http.createServer(app);

// Create the settings object - see default settings.js file for other options
var settings = {
    nodesDir: process.env.OPENSHIFT_DATA_DIR,
    httpAdminRoot:"/",
    httpNodeRoot: "/api",
    userDir: process.env.OPENSHIFT_DATA_DIR,
    uiPort: 8080,
    functionGlobalContext: { }    // enables global context
};

// Initialise the runtime with a server and settings
RED.init(server,settings);

// Serve the editor UI from /red
app.use(settings.httpAdminRoot,RED.httpAdmin);

// Serve the http nodes UI from /api
app.use(settings.httpNodeRoot,RED.httpNode);

server.listen(8080);

// Start the runtime
RED.start();

这是我的app.js：

我应该在Openshift仪表板中单独定义环境变量吗？感谢。

我通过在部署仪表板中定义此环境变量来解决它： app-root/data为str_val。我的node.js代码没有问题。

node red openshift用户目录
