@ShaMan123 kindly advice, I really need this, rather than using webview.

[joaortizro]

@ShaMan123 i've tried Math example from the repo but still same errors, @nolife08021 have you tried the mathExample, may be im missing something out...

[nolife08021]

@joaortizro I tried just now and this error comes out.

error: bundling failed: Error: Unable to resolve module mathjax-full/js/input/tex/AllPackages from /Users/admin/react-native-math-view/src/mathjax/Config.ts: Module mathjax-full/js/input/tex/AllPackages does not exist in the Haste module map or in these directories:
/Users/admin/react-native-math-view/node_modules/mathjax-full/js/input/tex

[nolife08021]

@joaortizro I able to run the mathExample now after install mathjax-full and transformation-matrix in react-native-math-view as error log mention. But I still wondering how to install it in my apps.

[ShaMan123]

Will look into it.
BTW iOS isn't working yet so file an issue if the fallback component isn't working

[ShaMan123]

I tried to reproduce the issue. It is something I ran into before but couldn't reproduce anymore.
To test the issue I installed the package on a new react-native app both with yarn and npm with no trouble.
Just in case I went through the config files for the example app and made them more safe, upgraded react-native and bumped the version.
I suggest you remove all node_modules + lockfile, download again, rebuild example app and see how it goes.
Make sure to follow these instructions
What version of react-native are you using?
If you are using with iOS be sure to add react-native-svg (this is a fallback until I finish linking the native code)
Report back so I can help.

[ShaMan123]

@nolife08021 @joaortizro I've added additional info in the ReadME. Suggest you guys give it a look

[ShaMan123]

@nolife08021 after installing if the bug persists try running:

cd node_modules/react-native-math-view && npm run postinstall

and report back.
Thanks

[ShaMan123]

Might have found the problem. bumped -> 3.4.1

[joaortizro]

@nolife08021 @ShaMan123 , i've managed to at least run the mathExample but now it seems there are some errors with the hooks

• node version : 12.4.0
• react-native-cli: 2.0.1
• react-native: 0.61.4

[nolife08021]

@ShaMan123 I'm facing this error after I removed all node_modules + lockfile and download it again.

Make sure it's not a problem with your environment, see this.

[ShaMan123]

I think that downgrading is not a good idea.

This error is not vital and can be disregarded

"react-native": "0.59.5"

I've edited the installation guide, make sure to follow the new instructions.

[ShaMan123]

and perhaps try the following:

1. Clean cache for npm and yarn (sometimes for yarn you need to do it manually by navigating to the cache dir and deleting it)
2. Reset cache for react-native (npm start -- --reset-cache)
3. Remove react-native global package (npm uninstall -g react-native)
4. Stop gradlew / restart your machine.
5. Make sure to clean and rebuild native code after installation (not enough to run react-native run-android)
