<p dir="auto">I installed with npm the babel-core and this files are empty, i need them for system js.</p>
<p dir="auto">When I install the latest babel-core I end up with browser.js and browser.min.js as empty files with no content just some white space, each file is around 4 bytes, compared to babel-core 5.8 where browser.js is 2MB.  I am using npm 2.11.3.  I don't see any errors or warnings on install everything appears fine, except those files are empty.</p>
