[!] (plugin babel) Error: Rollup requires that your Babel configuration keeps ES6 module syntax intact. Unfortunately it looks like your configuration specifies a module transformer to replace ES6 modules with another module format. To continue you have to disable it.

Most commonly it's a CommonJS transform added by @babel/preset-env - in such case you should disable it by adding `modules: false` option to that preset (described in more detail here - https://github.com/rollup/rollup-plugin-babel#modules ).

hi Arryangga, i'll have to know more about the codebase you're trying to run. I'm really no expert in rollup errors!

ethicalvats commented 5 years ago

Facing same issue! @arryanggaputra are you running it on react/react-native app ?? it has something to do with babel.config.js as it clearly says need to turn off the module transformation so I am playing with this setting

presets: ['module:metro-react-native-babel-preset'],

If I will find some solution will share

spencermountain commented 5 years ago

thanks @ethicalvats i'd be happy to support any solution you can find. Maybe this script should hunt-around in some obvious places for node_modules and babel configs. It's up to you cheers

matthewbal commented 3 years ago

I also had this issue running on a mid sized react native project, did you find a solution @ethicalvats ?

spencermountain commented 3 years ago

hey @matthewbal you may have more luck with smeijer/unimported it seems to do everything, i'm gonna add it to the top of the readme for this project. cheers
