Node.js Question

ExpressJS - throw er Unhandled error event

I created expressjs application using the following commands:

express -e folderName
npm install ejs --save
npm install

When I run the application with:
node app.js
, I have the following errors:

throw er; // Unhandled 'error' event
Error: listen EADDRINUSE
at errnoException (net.js:884:11)
at Server._listen2 (net.js:1022:14)
at listen (net.js:1044:10)

How to fix it?


You had run another server use the same port like 8080.

Maybe you had run node app in other shell, Please close it and run again.
