react-native-router-flux: Duplicate versions of react-native being installed

Got wrecked by this too. Fixed with the rollback to 3.38.0

watchman watch-del-all
rm -rf node_modules && npm install
npm uninstall react-native-router-flux
npm install --save react-native-router-flux@3.38.0
rm -fr $TMPDIR/react-*
npm cache clean
npm start -- --reset-cache

reinstall 3.38.0 for now npm install --save react-native-router-flux@3.38.0

I’ve been tearing my hair out over this issue, glad to come across the root of the problem

jest-haste-map: @providesModule naming collision:

This warning is caused by a @providesModule declaration with the same name across two different files.

Removing react-native-router-flux from my package.json and reinstalling node_modules causes no errors so it’s definitely react-native-router-flux.

Came here to post the same issue, looks like it was accidentally added to the dependencies in this commit: https://github.com/aksonov/react-native-router-flux/commit/34e2d7ac7eb09489c2fd7f19844bd38e27e969fc

I believe It should be listed as a peerDependency instead

yeah this has been destroying my day as well. as a quick work around, you can just go delete the dupe of react-native out of the node_modules folder within react-native-router-flux. Ugly, but will at least get you up and running for the time being

Same issue

Posting the above for convenience copy & paste 😄

watchman watch-del-all && rm -rf node_modules && npm install && npm uninstall react-native-router-flux && npm install --save react-native-router-flux@3.38.0 && rm -fr $TMPDIR/react-* && npm cache clean && npm start -- --reset-cache 

yep, either rollback or remove the folder manually, thanks for the workarounds

Same here, please update the package

same issue, please help to fix

Waiting for the fix I rollback to react-native-router-flux@3.30.1

It’s not related to yarn I believe. Because even if I install it with npm I get the same issue. I deleted my node_modules folder and cleared the npm cache, but the issue was persistent. Currently, I went ahead with a workaround which I read on a GitHub issue where I have to delete the node_modules/react-native-router-flux/node_modules/react-native package. I hope they fix this issue soon.

@abdurrahmanekr @asokol Can we publish this into npm its still showing 3.39.1 as the latest https://www.npmjs.com/package/react-native-router-flux

What worked for me was this sequence:

watchman watch-del-all rm -rf node_modules && npm install npm uninstall react-native-router-flux npm install --save react-native-router-flux@3.38.0 rm -fr $TMPDIR/react-* npm cache clean npm install --save react@16.0.0-alpha.6 npm start – --reset-cache

Rolling back to v0.38.0 or just deleting the react-native folder inside react-native-router-flux/node_modules/ and also delete symlink to react-native inside react-native-router-flux/node_modules/.bin/ will work for now.

Same by me, had to remove the react-native directory inside react-native-router-flux manually to make things work.
