events.js: 141 throw er; // Unhandled 'error' event

Solution 1
Check whether any other Terminal is running other Applications on the same port. This happens when multiple applications trying to access the same port, Its always FIFO.
Good Luck!!!
Solution 2
First Look for the other applications is running on the same port may be another node application.
To find the current process running on the same port use:
MAC:
You can try netstat
netstat -anp tcp | grep 3000
For OSX "El Capitan" or if your netstat doesn't support -p, use lsof
lsof -i tcp:3000
Then kill the process
kill pid
You can try to kill all node process use:
killall -9 node
Solution 3
ENOENT means that spawn was unable to find the binary you are looking for. Make sure that what ever you are trying to spawn is in your path.
In this case you probably don't have gifsicle installed.
Solution 4
Fixed the problem. There was a problem with the permissions for assets - if gulp can't take all assets. Then always there will displayed an error. I deleted the assets manually. I think i must be careful with(out) the "sudo" - command...

I'm trying to run node 4.2.2 on a Mac OS and i'm not understanding why every time i get this error message:
events.js:141 throw er; // Unhandled 'error' event ^ Error: spawn /Users/user/Documents/Projects/project-x/node_modules/gifsicle/vendor/gifsicle ENOENT at exports._errnoException (util.js:874:11) at Process.ChildProcess._handle.onexit (internal/child_process.js:178:32) at onErrorNT (internal/child_process.js:344:16) at doNTCallback2 (node.js:441:9) at process._tickCallback (node.js:355:17) c12320:project-x user$What's going wrong? If i run "gulp build" there is this output:

Admin over 8 yearsI already had installed gifsicle or imagemin-gifsicle, but it doesnt work.
-
Breedly over 8 yearsHow are you running this? How did you install gulp? What are the permissions for that folder?
ls -lwill give more information. -
Ignatius Andrew almost 8 yearsIts your local port, If localhost:\\3000 is already up and running, you cannot run another app on the same port. you get the above error.
