running `apps/native-component-list` and `home/` gets Duplicate module name: react-native error


#1

I’m trying send a few commits for expo/expo repository.
And I run apps/native-component-list and home/ for testing my code. But I got stuck in below error.

If you have some documents for running these apps or if you have the idea to solve this problem, please help me.

And I want to know how to use expo-yarn-workspace

Hi @ggtmtmgg - is it possible you have not checked out the react-native submodule in the expo repo? Try running git submodule update --init --recursive in the repo root, then run yarn install again and see if that fixes things for you.

@watanabe_yu - there is a readme inside that package’s directory with some information – see https://github.com/expo/expo/tree/master/packages/expo-yarn-workspaces . However, note that this package is only intended for use and supported inside of the expo/expo repo. You’re welcome to try using it elsewhere but ymmv.
