TypeError: /root/my-project/src/utils/Yuan.js: Duplicate declaration "React"

See original GitHub issue

Hi there, has anybody else get this error when running npm run build?

I started getting error like these using v1, then I thought using v2 should solve it but it didn’t.

Here is an screenshot, I’m getting the same error either in Ubuntu or MacOS, running Node 8.11 and 9.10

Thanks in advance.
