i want to install rollup-plugin-visualizer but its need to update rollup.

updated rollup from 1.8.0 to 3.1.0

got error

[!] RollupError: Node tried to load your configuration file as CommonJS even though it is likely an ES module. To resolve this, change the extension of your configuration to ".mjs", set "type": "module" in your package.json file or pass the "--bundleConfigAsCjs" flag.

delete node-modules folder and package-lock.json and install again npm i

got error

rollup-plugin-babel npm page says !!!

i have delete rollup-plugin-babel then install @rollup/plugin-babel.
now i got this error

i have find the solution.
At first changed format from 'esm' to 'cjs' in rollup.config.js

export default {

    ...

    output: [

             {

                format: 'cjs',

                ...

            },

       

    ]

};

then rollup.config.js changed to rollup.config.mjs
