That's the output if i enter "gulp build"
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!!!
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
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...
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.
this would not pertain to your error, but that error code can also run if a person is running node on multiple servers with the same address at the same time from their terminal.
Did you install imagemagick ?
brew install imagemagick
I had this same error at work on my Mac Book Pro. None of the solutions fixed it. I finally fixed the problem by restarting my computer. I often don't shut my computer off at night and put it in sleep mode so if your computer has been running for a long time try restarting it and see if that works for you.
so it throw an error ,Unhandled 'error' event,which means you need handle the error event,add function on this event and print the error,you will find the reason and your program will act normal.
