Duplicate export 'default'

[DaveWM]

It seems that when a module sets both module.exports and module.exports.default, rollup throws the above error. This is needed for node to be able to import commonjs modules using es6, see this discussion of the issue.

I've put together a gist which outlines the issue here. When you run rollup -c, you get the following error:

🚨   Duplicate export 'default'
x.js (8:22)
6: export default x_1;
7: export { x_1 as __moduleExports };
8: export { default_1 as default };
                         ^
9: x_1.default = default_1;

Anyone know what's happening here?

I think this might be related to #110

Thanks for the repro and sorry for the long delay — this is fixed in 7.0.2
