Question

I’m getting some random errors when running:

forge run web 

in my app.

$ forge run web
[   INFO] Forge tools running at version 3.3.11
[   INFO] Checking JavaScript files...
[   INFO] JavaScript check complete
[   INFO] Verifying your configuration settings...
[   INFO] Configuration settings check complete
[   INFO] { [Error: listen EADDRINUSE] code: 'EADDRINUSE', errno: 'EADDRINUSE', syscall: 'listen' }

Any idea what might cause this error?

Answer 1

The error is cause by an application already listening on the port you’re trying to listen on.

You can use ps aux | grep node to see if there are any node processes running.
Then kill them using kill pid where pid is the process id

example:

ps aux | grep node
37211   0.0  0.2  3029484  17852 s018  S+    5:35PM   0:00.28 node ./web.js
kill 37211
