I experienced the same issue, I'm using expo managed workflow, and cleaning cache has worked for me.

expo r -c is the command I used.

I was getting the same problem, after running 'npm install --global expo-cli' it solved the issue or you can run npm install

You are getting this problem based on how you created the program. So, when I created it from the terminal, following this instruction: https://reactnative.dev/docs/environment-setup it worked, but when I tried to create the program inside of the terminal in an existing project, I got the error.

you don't really need to delete node_modules folder.

just update it by typing:

1/ npm : npm install

2/ yarn : yarn install

in your terminal. That will update the node_modules folder content as well as creating all missing files without the need to reinstall it from scratch.

I had this issue after installing @react-native-community/hooks

You don't need to delete any node_modules folder.

Installing react-native again solved the problem for me.

npm i react-native

It happened to me when you tried install @react-native/bottom-tabs. But I've installed this package with npm, so I removed this package and installed it again with yarn and it fix my problem with no need to remove node_modules.
