[update error]Duplicate module name: TouchHistoryMath

See original GitHub issue

I update react-native to 0.24.1 and install the peer dependency react @latest(15.0.2) then run `react-native upgrade` and `react-native run-android`. and get the error as following:

Failed to build DependencyGraph: @providesModule naming collision: Duplicate module name: TouchHistoryMath Paths: /Users/Mervyn/CodingNet/playwithreactnative/node_modules/react/lib/TouchHistoryMath.js collides with /Users/Mervyn/CodingNet/playwithreactnative/node_modules/react-native/Libraries/vendor/react/browser/eventPlugins/TouchHistoryMath.js

This error is caused by a @providesModule declaration with the same name accross two different files. Error: @providesModule naming collision: Duplicate module name: TouchHistoryMath Paths: /Users/Mervyn/CodingNet/playwithreactnative/node_modules/react/lib/TouchHistoryMath.js collides with /Users/Mervyn/CodingNet/playwithreactnative/node_modules/react-native/Libraries/vendor/react/browser/eventPlugins/TouchHistoryMath.js

Press <enter> to close the window

and I solve it by downgrading react version as the tips of react-native’s npm warn to 0.14.5.

I want to know the reason. Anybody meets the same situation?

I was getting errors like

Failed to build DependencyGraph: @providesModule naming collision:
Failed to build DependencyGraph: @providesModule naming collision:
Duplicate module name: accepts
Duplicate module name: accepts

I solved it by deleting npm’s cache .npm and rerunning packager with --reset-cache

rm -rf ~/.npm
