React Native - console.error: 'React Native version mismatch

Question

I am using EXPO and React Native, the app work running completely fine until it suddenly stopped when I made a new file and even when I deleted it, the error stayed.

I have updated React Native to V0.56.0 but it is still showing the error:

console.error: 'React Native version mismatch.

Javascript version: 0.56.0 Native Version: 0.52.0

Before I updated it was:

Javascript version: 0.54.0 Native Version: 0.52.0

and still causing the same error?

Any ideas on how I fix this and which command I use to update the Native Version?

Solution 1

Go to package.json file inside your project folder

Where you can find code like this

"dependencies": {
    .....
    "react-native": "^0.54.0",
    ......
},

change the react-native version to 0.54 and save file.

Then go to the terminal and redirect to your project folder and hit the command

npm install  && expo start -c

First step: I changed the value of expo in package.json file to the latest supported version, according to expo documents(visit here).
