I am trying to run a nodes app. I run node app.js. When I do, I get this error:
node:events:346
throw er; // Unhandled 'error' event
^
Error: listen EADDRINUSE: address already in use :::5000
at Server.setupListenHandle [as _listen2] (node:net:1311:16)

Emitted 'error' event on Server instance at:

errno: -48,
syscall: 'listen',
address: '::',

}
I spent hours looking at possible solutions online but none have worked so far. Same codebase works great on a different machine. This error happens on Mac M1 chip.
Does anybody have any idea how to fix this?
I tried finding processes running on 5000, I tried to kill them etc... nothing worked so far. I am running node 15.14.0.
I am on a M1 Chip, running macOS Monterey
How can I fix this error?
You should disable AirPlay on your mac. Because macOS Monterey started to listen to port 5000 and 8000.
System Preferences > Sharing > untick AirPlay Receiver
For macOS Ventura:
System Settings > General > disable Airplay Receiver
Lee Jeonghyun was correct. The reason why kill -9 PID would never work is because of this:
https://developer.apple.com/forums/thread/682332
Control Center on Monterey is listening on 5000 as well.
I changed the port number in my nodejs app and the app started working again.
List all process on mac:
sudo lsof -PiTCP -sTCP:LISTEN
You will see a list of process and its ports. Choose the process PID on 5000 port or any other port in the error: EADDRINUSE: address already in use...
Finally kill it if it is not an important app for you
kill -9 1234
This also happened to me after upgrading to macOS Monterey from Big Sur.
Every port that I passed to my Node app appeared to be already in use.
You need to disable AirPlay on your mac.
System Preferences > Sharing > untick AirPlay Receiver
Screenshot
Did some investigation and found that macOS Monterey is using 5000 port for Airplay-Receiver. If you really want to use the port, then disable that feature in "System Preferences->Sharing".
Below medium post helped me:

As part of this basic tutorial, I downloaded the code from this repo, and attempted to run it with the command ./gradlew run on an Ubuntu 20.04 environment.
This resulted in the following error:
> Task :browserDevelopmentRun
✖ ｢wds｣: Error: listen EADDRINUSE: address already in use 127.0.0.1:8080
✖ ｢wds｣: Error: listen EADDRINUSE: address already in use 127.0.0.1:8080

code: 'EADDRINUSE',
errno: -98,
syscall: 'listen',
address: '127.0.0.1',
port: 8080
}
The process seems to be the only one running on this port, and attempts to get rid of any other processes using port 8080 (sudo kill -9 'sudo lsof -t -i:8080', killall node, etc...) have no effect. The conflicting processes seem to both come from within the tutorial web app.
Changing the port using a .env file also did not work. No matter what port is set (8081, 3000, 83000, etc...), there is still the error of port 8080 already being in use.
Does anyone know a solution to this issue? Thanks!
So while I didn't figure out exactly which dependency was causing this issue, on trying out a couple of the pull request on the repository, I found that this one: https://github.com/kotlin-hands-on/web-app-react-kotlin-js-gradle/pull/11 fixes the problem. Hopefully, it will be merged into the main branch soon!
When I update the project Files I get this issue given Below:

[nodemon] app crashed - waiting for file changes before starting...
I already try all this point to short out this issue given below
1.I manually stops the all node services than again I try npm start It's not worked if i change port 4001 it's work after, some time again same issue port 4001.
2.I Increase the nodemon file watcher size but still this issue not get solved.
But When I restart My PC again then nodemon is working on same port.
So How I can solve this issue, If I don't want to change my port and can't restart my PC.
Adding --signal SIGTERM to nodemon command line fixed for me. You can have more details at nodemon project # github.com
The issue occurs due to a thread still running when nodemon restarts the app, and this thread is already using the port you want to use. You can confirm this with these steps:
Make nodemon crash. You should see something like the error posted by OP
hit CTRL+c when it happens to stop nodemon
enter netstat -napt | grep [YOUR_PORT], replace [YOUR_PORT] with the port number you are using. In the OP's case it's 4000
you should get the process listening on that port. The command will return something like this:
ff#darkpc:~/dev/dp/graphql/teste1> netstat -napt | grep 4000
(Not all processes could be identified, non-owned process info
will not be shown, you would have to be root to see it all.)
tcp6 0 0 :::4000 :::* LISTEN 31837/node8
if you try to run nodemon again it will crash!
kill the process using your port with kill 31837 in this case 31387 is the PID of node8 as you can see above
run nodemon again and it will work.
Adding the --signal SIGTERM to nodemon command line will kill the main process and all it's threads and should fix the problem.
500 Internal Server Error for URL:http://localhost:8100/api/timeline dev4living/HeyCommunity

-What should i do to fix this error?
-Your assistance will be very much appreciated.
The error states that the port you are trying to use is already occupied. Please check the app running in the port 8100 and stop that and try to run the app again. Changing the port number to something else apart from 8100 will also solve the problem.
The error is pretty self-explanatory buddy. It just means that the address you have used, i.e, the port number is currently in use by something else.
2 possible solutions:
Simply change the port number
using cmd to get the list of processes running. Identify the process running on that port. And use taskkill -pid command. Refer this stack overflow post for details regarding this method
I have installed KrakenJs on Windows 7. I have created project by using following command :
Yo Kraken
When I tried to run the project, it is giving following error (even after restarting system) :

Can some one guide me what I am doing wrong and how it can be rectified
Look into next two possibilities:
Try opening your command prompt 'As Administrator', that shall solve the issue if you are lacking permissions to open port.
Temporarily change the port used in Kraken to something irregular and long, example: 32482
Then move on from this, if 1st - then you have solved an issue, if 2nd - you are very likely trying to open a port, which is already used by other application.

I've developed a node.js script on my windows seven machine and it's working fine. but when I run it on my Ubuntu 12.04, the following error shows up and halts my app:
throw er; // Unhandled 'error' event
^
Error: listen EACCES
at errnoException (net.js:901:11)
at Server._listen2 (net.js:1020:19)
at listen (net.js:1061:10)
at Server.listen (net.js:1127:5)
at Object.start (/httpServer/httpServer.js:9:34)

at Object.Module._extensions..js (module.js:474:10)
at Module.load (module.js:356:32)
at Function.Module._load (module.js:312:12)
and the point that caused error is .listen(80) in this line:
http.createServer(onRequest).listen(80);
^
I've also tried some other port numbers (like 100, 300, 500,...) instead of 80 and the error was still the same.
On Ubuntu you can't listen on ports < 1024 without root privileges. Try running node under sudo.
sudo node app.js
You probably have apache running on port 80, so it's conflicting.
Use another port (NOT within 0-1023), or disable apache.
Cheers
You probably have something else running on port 80, so it's conflicting.
Read here to find out what is using port 80 and stop it
http://www.cyberciti.biz/faq/find-linux-what-running-on-port-80-command/
Usually it means another server like apache is enabled. so stop it.
sudo service apache2 stop
or You have npm start already running in another terminal
or skype is running. in which case go to settings and change it's port. logout n login
Go to Tools -> Options -> Advanced -> Connections and uncheck the box "use port 80 and 443 as alternative".src
or use another port
http-server -a localhost -p 8000
I suggest to install the latest node packets, maybe directly from Node.js server, maybe compiling it.
Try to set a port which is not reserved to any service, like 3700.
Could be heplful to see some other fragment of code, though.
This can also be caused if you have something else already listening on that port - you can try changing the port from the typical default 80 to something more like 10014 and see if that helps!
I was able to rectify the error by explicitely mentionining the "IP address" along with the port when listening to the server.
