[Help] Module parse failed: Unexpected token . Babel not working correctly

Developers
#1

npm install and make get many similar errors like the following.

ERROR in ./node_modules/react-native/Libraries/Animated/src/Easing.js 64:16
    Module parse failed: Unexpected token (64:16)

The errors looks like babel did not work for node_modules/react-native/Libraries .
I got no errors with stable_6433, but we’re building features branching from stable.

My babel.config.js stays the same with 6433 and not using .babelrc.
I found .flowconfig was removed from master branch. Is it relevant ?

already using @babel/preset-env, @babel/preset-flow, @babel/preset-react
need to add more plugins to webpack.config.js ?

Delete node_modules folder and try again, make sure you use latest LTS versions for node and npm.

#4

What version of node, npm are you using?

#5

Yes. i’ve cleaned up everything from the beginning.

git clone https://github.com/jitsi/jitsi-meet.git
git checkout stable/jitsi-meet_6433
npm install
make

using node v12.22.9 and npm 6.14.15

Add only 1 line

import { NativeModules } from 'react-native';

on top of the file react/features/base/participants/middleware.js
where we’d like to do extra password feature via NativeModules.ExternalAPI.sendEvent

but make failed after adding the first line.

Is it causing circle import ?

#6

You need node 16 and npm 8

#7

stable 6433 is an older release (package.json says node >=8 and npm >=6)
I’ve tried node 14 and npm 6 still make failed.

#8

This is wrong, adding react native code in a part executed by web and mobile
