I got around the problem by installing react, react-redux, and react-native-scripts manually and then running the same command (create-react-native-app) npm install -g react npm install -g react-redux npm install -g react-native-scripts After I did that, it errored out saying that I have npm 5 but it needs npm 4. So I downgraded npm to the last of the version 4 sudo npm install -g npm@4.6.1

p.s. After all this, it took a really long time to run the create-react-native-app but running it with --verbose option helped speed it up and it succeeded.

I’m glad it helped you moving forward. I would advice to give up on npm 5 altogether and downgrade to npm 4 or even switch to yarn. Installing react, react-redux globally will cause you other conflicts later when you will want to upgrade, or start another project. If you are in a hurry, you can just try:

yarn create react-native-app test-rn
