404 ...foo.js.map not found

[ghost]

Running jspm@beta with an app with two files:
1(main.js) import './test';
2(test.js) console.log('here');

I don't notice this in Chrome, and everything else works fine, but it might be confusing for new adopters of jspm.

Which browser are you getting this in?

Sorry, that is in Safari Version 9.0 (11601.1.43)
I think it might be coming from browser.js in babel because I noticed this will trying to use it without JSPM after I filed this issue.

Yes, it seems it is due to this line in Babel:

var mapFileCommentRx =
  // //# sourceMappingURL=foo.js.map                       
  /(?:\/\/[@#][ \t]+sourceMappingURL=([^\s'"]+?)[ \t]*$)|(?:\/\*[@#][ \t]+sourceMappingURL=([^\*]+?)[ \t]*(?:\*\/){1}[ \t]*$)/mg

Which is being detected not as a regex but as a sourceURL comment in Safari.

It's a Babel thing / Safari bug. It may be worth mentioning on Babel's issue queue if they don't already know about it.
