I'm using mac OSX Mavericks

[ErwanGuillon]

Same error here.

It seems that too many process are opened. But I'm not an expert in node so ...

BTW I'm on Mavericks if it matters

[ErwanGuillon]

I found some infos but don't know how to fix ...

It's like the second result on Google when searching for the error message:
gruntjs/grunt#788 (comment)

Increase your ulimit.

[ErwanGuillon]

It's the first thing I tried and it doesn't work...

If you look at the issue you linked, it's the same for others. Increase ulimit doesn't work for everyone.

👍 Setting ulimit did not work for me either. OSX Mav as well. Is there some way to throttle imagemin and limit to a certain number of open file descriptors?

[eightyfive]

This did work for me (Mac OS X):

ulimit -S -n 2048 # or whatever number you choose

(source superuser.com)

ulimit worked for me. OSX Mavericks. Im happy again.

[pascaloliv]

@8y5 : This fix work perfectly on OSX Mavericks. Thank you.
👍 ulimit -S -n 2048

[gilesbutler]

ulimit -S -n 2048 works for me but it's not permanent, every time I quit Terminal I get the Error: spawn EMFILE again. Is there anyway to make it a permanent change?

[gilesbutler]

Thanks for the link @kevva. I tried everything they suggested but couldn't get it working, I even bought the app Lingon3 which they mention and that didn't work.

In the end it was fairly simple, I just added the command to the bottom of my zhsconfig and it works fine now.

ulimit -S -n 2048 # work for me ,thanks!

[ouzhenkun]

add "ulimit -S -n 2048" to ~/.bash_profile

[BerkeleyTrue]

ulimit -S -n 2048 # worked!

[helena-sopra]

ulimit -S -n 2048 #worked for me too 👍 :)

[oluul]

ulimit -S -n 8196 # worked!
