#39 try referring to this and do tell if you still have any problems. It will be helpful if you can share your package.json too.

it's no change

[cookmaster]

at least ,thank you very much.

[AmirFarhan]

It seems like you did not load jquery and leaflet as your dependencies. Do the following in your repo:
npm install jquery
npm install leaflet

[cookmaster]

wow,i try it,thank you

[cookmaster]

If you are running node js on Windows, edit the package.json file and change line 8 from:

"watch": "./node_modules/gulp/bin/gulp.js"``
to

"watch": "node ./node_modules/gulp/bin/gulp.js"
