Failed to gulp the js file

Yi-xin

Everytime I try to gulp the js file,it turns out "Only one default export allowed per module".How could I solve this problem?

Here is the log:
npm install
D:\myworks\myweb\flarum\vendor\flarum\core\js\forum>gulp
[15:33:30] Using gulpfile D:\myworks\myweb\flarum\vendor\flarum\core\js\forum\gulpfile.js

Can you explain a bit where you run the command and how you loaded node_modules etc? A bit more to go on would be great ?

We forgot to run the command "bower",we were too careless to download the basic package.
