Hey jjchula, thanks for reporting this issue!

React Native, as you've probably heard, is getting really popular and truth is we're getting a bit overwhelmed by the activity surrounding it. There are just too many issues for us to manage properly.

• If you don't know how to do something or something is not working as you expect but not sure it's a bug, please ask on StackOverflow with the tag react-native or for more real time interactions, ask on Discord in the #react-native channel.
• If this is a feature request or a bug that you would like to be fixed, please report it on Product Pains. It has a ranking feature that lets us focus on the most important issues the community is experiencing.
• We welcome clear issues and PRs that are ready for in-depth discussion. Please provide screenshots where appropriate and always mention the version of React Native you're using. Thank you for your contributions!

Try removing the react and react-dom dependencies, if you can. RN ships with it. Are you using npm3?

Getting the same thing when upgrading from 0.17 - 0.18.0-rc

[satya164]

Try deleting your node_modules folder and run npm install again.

[brentvatne]

Make sure you're using npm3 also!

edit: actually it seems that is not required currently, however it may solve this problem.

[jjchula]

react v0.14.x has "fbjs" devDependency.
While v0.14 to v0.17 of react-native have no "fbjs" dependencies, v0.18.0-rc does.
So, with npm2, if the RN project also includes package with react peerDependency, Bang!

Yeah, what @jjchula said. After deleting the node_modules folder, and run npm install again, i get:

[1:58:54 PM] <END>   Building (deprecated) Asset Map (1220ms)

With npm@2

[josebalius]

I tried it with npm@3 and ran into this issue: #4296 however #4296 (comment) seems to fix it for me.

[masom]

Fixed by forcing npm install -g npm@2.

EDIT: Nope, still broken with npm 2.
