npx react-native-clean-project

Get the following error:

[Pedro Madruga]

Does it happen every time?

[Victor Martins]

this error also happened to me

[Pedro Madruga]

I'm not able to replicate this with a new RN project? Was that the case?

[Tolga Berk Ordanuç]

is there any solution?
it just happened to me.

(edit)
i was just in the android dir thats why it thrown an error.

[Pedro Madruga]

So this error happens when you're in the android directory? I'll give it a try tonight.

[Iamandi Radu]

Tried it after upgrading to RN 0.64.1. Had the same error as mentioned above.
Ran yarn, retried cleaning and it worked.

[AP Fritts]

This is because you have removed your node_modules directory and your build.gradle file requires a resource in order to load your project and then clean your project.

Hello,

I'm experiencing the same issue (React Native version is 0.63.4). @iamandiradu solution didn't work although I didn't yet update version.

Have a nice day.

[MaganAnkur]

I am experiencing the same issue with 0.66

Closing because the discussion has been moved to #79 . I've also released a potential fix - please check that thread. Thanks.
