Have you tried installing it?

[uonick]

Yes

[gscottqueen]

same error here, digging in this morning but did @uonick find a fix?

[uonick]

@gscottqueen nope 😞

[LinusBorg]

Will try to reproduce this tonight, seems very strange.

This is the module: https://www.npmjs.com/package/uglifyjs-webpack-plugin

Here it's defined in package.json: https://github.com/vuejs-templates/webpack/blob/develop/template/package.json#L111

And here it's being imported: https://github.com/vuejs-templates/webpack/blob/develop/template/build/webpack.prod.conf.js#L12

I really don't see where this should break ...

[gscottqueen]

@uonick and @LinusBorg fix was reported here https://github.com/webpack-contrib/uglifyjs-webpack-plugin/issues/217,

npm update uglifyjs-webpack-plugin
npm run build

worked for me

[LinusBorg]

Thanks!
