Errof happen when running "gulp dist "

Hi All,

I met one problem when running “gulp dist” under the folder app:
/home/paws/mediasoup/mediasoup-demo/app/gulpfile.js
58:21 error Unexpected use of file extension “json” for “./package.json” import/extensions

:heavy_multiplication_x: 1 problem (1 error, 0 warnings)

Any idea what’s the problem here?
