Answer 1

This is might be due to the limit on file open files on mac. By default it is set to low. You will need to increase the default size.

$ echo kern.maxfiles=65536 | sudo tee -a /etc/sysctl.conf
$ echo kern.maxfilesperproc=65536 | sudo tee -a /etc/sysctl.conf
$ sudo sysctl -w kern.maxfiles=65536
$ sudo sysctl -w kern.maxfilesperproc=65536
$ ulimit -n 65536 

Refer this link for more details.

its happening in windows 10... do you know what the command for windows? – Zurek

Having same ulimit on kern.maxfiles and kern.maxfilesperproc got me random crashes of different programs while trying to build stuff (because node depleted all the limit and other programs couldn't open files). Also, 65k is a bit of small limit considering current size of node_modules =) – Effluence

Thanks! You are the best! I had this issue when trying to publish thru expo – Prodigious

This worked for me, but with increasing to 524288 – Capuche

Answer 2

I was facing similar issue. I tried with maxfiles=65536 but got the same error.

Then I tried with 524288, as suggested by one in comments and it worked.

Command:

echo kern.maxfiles=524288 | sudo tee -a /etc/sysctl.conf
echo kern.maxfilesperproc=524288 | sudo tee -a /etc/sysctl.conf
sudo sysctl -w kern.maxfiles=524288
sudo sysctl -w kern.maxfilesperproc=524288
ulimit -n 524288 

Hope it will help others too

sudo launchctl limit maxfiles 16384 16384 && ulimit -n 16384
