react-native undefined is not an object (evaluating RCCManager.setRootController)

Question

I'm trying to make a simple react-native app with redux and redux-saga tie-ins. Unfortunately, when I try to run the app (whether using react-native run-ios or running through Xcode, I get the following error:

Strangely enough, when I ported things like the Counter example for redux-saga to react-native or other examples I don't have this issue. I'm wondering if someone could help point to where things could be going wrong?

Answer 1

So turns out I just needed to link some more libraries together.

Reinstalling these components helped:

npm install --save react-native and npm install --save react-native-controllers

followed by rnpm link fixed the issue

Answer 2

Here is another solution based on my own failure: Through rechecking iOS installation doc, I found out some tricky differences in the #4 requirement: It clearly says project row instead of target row. This time I selected 'project' row and add do what the #4 instruction told to do. Then it solved the problem. Hopefully my solution will be found helpful.

Answer 3

I faced a similar problem and it was because somehow the setup I made for the Xcode project were lost, so following the instructions I made them again and the problem was solved.
