'define' is not defined

Start with react-tagsinput.js and inspect the generated wrapper around define.amd, then determine whether the report is a runtime failure or a question about the bundle format. Check how this file is loaded in the reported environment; done requires a reproducible failure and a clearly specified change or explanation.

I have been trying to find out where 'define' is on react-tagsinput.js.
For define.amd on the second line.
