Import and require not work

[georgezouq]

Import this package into my project (rollup) in this way:

import { generate } from '@arco-design/color';

Error: SyntaxError: Cannot use import statement outside a module

And I see in arco-design project palette.js, it uses require to import package

const { generate } = require('@arco-design/color');

And stall, it does not work for me

Error: Cannot find module '@arco-design/color'

I am not sure if this is because commonjs project is import into esnext project.
Should this package publish in the build version instance source code?
