Got the solution

run below command to solve the issue
ENOSPC means that there is no space on the drive.

using the following command in a terminal window we can simply increase the limit

echo fs.inotify.max_user_watches=582222 | sudo tee -a /etc/sysctl.conf && sudo sysctl -p

For Arch Linux add fs.inotify.max_user_watches=524288 to /etc/sysctl.d/99-sysctl.conf and then execute sysctl --system. This will also persist across reboots. {source stackoverflow}

How do you solve this problem? I really don't know what's going on here, can you help me?

chachaxw on 9 Oct 2016

@chachaxw are you able to run the react naive package manager.
if you unable to run the react native package manager and get the error related to "ENOSPC" than my solution will help you what i did as mentioned in above comment

tulasi-ram on 10 Oct 2016

@tulasi-ram I have solved this problem. I forgot install watchman

chachaxw on 12 Oct 2016

Looks like this is solved?

Feel free to re-open or file a new issue if there are still problems starting the packager with newer versions of RN.

I am experiencing this error after updating to OSX Sierra and installing Xcode 7.3. Prior to the update I had Yosemite and Xcode 7.2.

Any suggestions on how to resolve this?

artforlife on 28 Oct 2016

Thank. You. So. Much.
Hey, Facebook, don't you think it might be good to fix this? You have a lot of people using React native on Ubuntu!

iboxgithub on 24 Feb 2017

@iboxgithub, what is the fix? Would you mind submitting a pull request for it?

ericvicenti on 24 Feb 2017

Hi, actually I just used the workaround, that's why I let a message for FB devs.
this worked for me by just running it in my terminal (Ubuntu)
echo fs.inotify.max_user_watches=582222 | sudo tee -a /etc/sysctl.conf && sudo sysctl -p

iboxgithub on 25 Feb 2017

Ha... you are a FB dev...my comment looks weird now :1st_place_medal:

iboxgithub on 25 Feb 2017

No worries, all of us at FB are just people!

Maybe you could add this workaround to the troubleshooting page?

ericvicenti on 25 Feb 2017

Done, with some explanation in order to understand why this happens, let me know if it is ok
