create-react-native-app: Error creating new app with "create-react-native-app"

Description

I tried to create a new react native app using the command “create-react-native-app” I’m using window 8. I got the following terminal error

install create-react-native-app globally
run create-react-native-app some-project-name

let me know if you still have this error. anyone who replies and does not clearly say “i tried the 4 steps” and indicate whether it was yarn or npm or both, then i will delete your comment, sorry.

Hi, on mac I had to put the following: sudo sysctl -w kern.maxfiles=5242880 sudo sysctl -w kern.maxfilesperproc=524288 Then it worked!

I hope it cannot dommage anything (new values are pretty high)…

Thanks for your help. It works now.

I installed watchman executed touch .watchmanconfig and git init then executed sudo sysctl -w fs.inotify.max_user_instances=1024 sudo sysctl -w fs.inotify.max_user_watches=12288

See this new issue: https://github.com/react-community/create-react-native-app/issues/382

try running npm set registry https://registry.npmjs.org/ it worked for me

Thanks a lot! @yogur solution worked for me

I installed watchman
executed touch .watchmanconfig and git init (sounds weird but is a must)
then execute

sudo sysctl -w fs.inotify.max_user_instances=1024
sudo sysctl -w fs.inotify.max_user_watches=12288

In my particular case i used 122288, since you have installed watchman the system tells you if this number is enought or have to be greater.

Try creating a project using another command: react-native init <projectname>

try using react-native init <Project Name> instead of using create-react-native-app

try running npm cache clean or yarn cache clean, it seems like one of the tar downloads was interrupted
