React Native Error: Unable to resolve module `./index`

Question

I have a newly created application using React Native. The app contains a simple login form and a fetch query, nothing complicated, few css and components.

I tried to implement Facebook, and after a LOOOT of struggle, I stopped receiving Facebook errors, while now, I get this error which makes no sense when I run react-native run-android :

No screen shown, nothing, diretcly this 500 error. I searched all over and over for a solution, I even added the form for Gradle, re-installed all npm packages after rm rf node_modules.. still the same error.

implementation ("com.facebook.react:react-native:0.58.5"){force = true}

Solution 1

Used npm start -- --reset-cache to run Metro Bundler and it worked. Found this solution looking for the answer to the same issue, SO post that helped me.

Solution 2

I think this question might be related to Unable to resolve module `./index` So the question is, did you try to run the app before you connected facebook? If it worked before then we might have a different issue. However, it's similar to this bug: https://github.com/facebook/react-native/issues/24112

A fix has been released a few hours ago. Please upgrade to react-native 0.59.2.

react-native upgrade

Solution 3

Thats an error of your backendserver ... look inside the config and remove the module which can't be found

Given the correct path where ? the thing is that I don't understand the error, I don't know where a module called ./index is being set !

Can you describe this deeply to make it clear to the OP?

The problem was that initlally the project was built under expo, so index was deleted.

upgrading to 0.59.2 fixed it for me

In fact it appears to be nothing related to facebook
