Node.js 在ctrl+;C
我与heroku启动了一个新的socket.io项目。服务器在windows上本地运行良好。我用npm start启动它,但当我用ctrl+c关闭它时,我在控制台中出现以下错误:Node.js 在ctrl+;C,node.js,heroku,npm,Node.js,Heroku,Npm,我与heroku启动了一个新的socket.io项目。服务器在windows上本地运行良好。我用npm start启动它,但当我用ctrl+c关闭它时,我在控制台中出现以下错误: npm ERR!

我一直在寻找解决办法,但我所能找到的很少一点办法都没有解决。我尝试过更新npm和节点,再次运行npm安装,清除npm缓存,可能还有一些我记不起的其他操作
这是我的index.js
const express = require('express');
const socketIO = require('socket.io');
const path = require('path');
const PORT = process.env.PORT || 3000;
const server = express()
.use(express.static(__dirname + '/client'))
.listen(PORT, () => console.log(`Listening on ${ PORT }`));
const io = socketIO(server);
const pg = require('pg');
var connectionString = "postgres://jdirjtnfueksiw:823e80fbae9599f0d6797f82342d83bccf1caea764b8a1659356f3ee89r69f94@ec1-78-222-138-451.compute-1.amazonaws.com:5432/jf84jd75jgu26d5?ssl=true";
pg.connect(connectionString, function(err, client, done) {
if (err) {
throw err;
}
else {
console.log('Database connection test successful');
}
});
io.on('connection', function (socket) {
socket.emit('connected');
console.log('New connection from ' + socket.request.connection.remoteAddress);
socket.on('disconnect', function () {
console.log('Player left');
});
});

谢谢您的帮助。在
index.js
中,您可以尝试输入以下代码:
process.on('SIGINT', () => {
process.exit();
});
我认为问题在于Ctrl+C终止了应用程序,但仍有一些进程在后台运行。这将确保它被终止
希望这有帮助 我也看到了同样的事情。并不是每次都发生。我使用的不是
socket.io
,而是express
。我不认为这是一个大问题,但似乎有一些信号我们(表达?)没有正确处理。让我们看看悬赏是否能帮助我们找到答案尝试一下。。。。如果成功的话,我会给你赏金的!深入研究,但人们建议,仅仅调用process.exit()
实际上并不能正常关闭Express…这方面似乎有一些Express文档:
