Sorry this comes back again with the latest 0.56. No steps to reproduce, the startup just won't work.

Description

This appears to be a regression as we've seen this before. The app refuses to start.

Reproducible Demo

The entire project is shared on Dropbox. It just refuses to start:

Seeing the same issue

[patrice4github]

Have you tried rebooting?

[atyenoria]

I came across the same issue just now. npm reinstalling and rebooting work fine.

[CodeMuz]

Check if $ yarn start works. The metro bundler wasn't able to run on port 8081 for me and I needed to run $ killall node

[patrice4github]

I think that's what it is, why rebooting fixes it. The process gets a hang of the port 8081, and somehow won't release it. I call this a bug. There should be a proper termination of the metro bundler so the port is always released properly.

Restarting worked for me as well - thanks!

[react-native-bot]

It looks like you are using an older version of React Native. Please update to the latest release, v0.57 and verify if the issue still exists.

The ":rewind:Old Version" label will be removed automatically once you edit your original post with the results of running react-native info on a project using the latest release.

[DalerAsrorov]

Thanks @CodeMuz, $ killall node and then $ rm -rf ios/build/ && react-native run-ios worked for me.

[kaushal9678]

Just close your current terminal window and run again ios, android commands. It will work. It worked for me.

Thanks. It solved my problem

[Digvijaykumar21]

digvijay@digvijay:~/Desktop/test$ kilall node

Command 'kilall' not found, did you mean:

command 'killall' from deb psmisc

Try: sudo apt install

digvijay@digvijay:/Desktop/test$ killall node
node: no process found
digvijay@digvijay:/Desktop/test$ killall -s KILL node
node: no process found
digvijay@digvijay:/Desktop/test$ killall --s KILL node
node: no process found
digvijay@digvijay:/Desktop/test$ killall node
node: no process found

[ramseykes]

Maybe you moved the file

[kaushal9678]

Just remove your app from the emulator or device and close the terminal that running bundler. Now start the process again by calling react-native run-android or iOS it will work.

[kelset]

Closing as it seems that it's just a caching issue - thanks everyone for the feedback!

[Youn-ha]

Rebooting fixed my problem out too. I tried every other methods but all failed. thanks for everyone

I've seen this on MacOS when building on CircleCI (the android app).

Error: ENOENT: no such file or directory, open '/Users/distiller/repo/android/app/build/generated/assets/react/<apname>/release/CodePushHash'

I haven't found the issue yet

[raimonkh]

@toro705 in our case we created those files manually as the build process only required they "existed" although empty...

[ryancwalsh]

Just close your current terminal window and run again ios, android commands. It will work. It worked for me.

Thanks @kaushal9678 . I was in Homestead Vagrant. I exited out of that terminal session, ran vagrant ssh again to get back in, ran npm install again, and then npm start worked without error.
