Question

Everything working and then suddenly got RNMathView" was not found in the UIManager.

Opened this issue 3 years ago · 8 comments

Everything worked fine, and it suddenly stopped worked.
I deleted all files related to my project, removed and reinstalled math view, and I kept getting this error

This is the file I'm using
`import React from 'react';
import {View, Text} from 'react-native';
import MathView from 'react-native-math-view';

const App = () => {
return (

Hello

);
};
export default App;
`

This is the error I get...

Invariant Violation: requireNativeComponent: "RNMathView" was not found in the UIManager.

This error is located at:
in RNMathView (at MathBaseView.tsx:31)
in Unknown (at MathView.tsx:17)

[UPDATE ]

Now I've created a new project, hoping to just migrate files, and I'm getting that it's missing mathjax...!

Yeah well react native is quite horrible.
Unfortunately don't have to enough time to spend on this project.
Keep trying.
If you've updated react native it's probably the reason.
I understand the frustration.

If you're working on android kill gradlew

thanks @ShaMan123 I'll try that.

This is a very wonderful project, hopefully if everything works fine in a new future I might help with it!

Okay, didn't work haha. I guess I'll have to display stuff manually for awhile lol.

I faced similar issues in my projects. Kill gradlew, clear yarn cache, clear react native serve cache, reinstall everything
smash your machine :)

Good news, it's not Math View, apparently it's everything...

I guess you can close the issue (?)

Yes, sounds like a caching issue of the react server
