            }
        }
    }
}

When it is possible, I'm using bower, but sometime packages are required by other library (for example, ssr-window is required by swiper), so I can't change it.

I've tryed to delete npm-asset folder and all vendor folder, but it does not work.

Maybe I should handle npm package instead npm-asset, how suggested here: https://github.com/tanakahisateru/yii2-app-basic-npm

This is fxp/composer-asset-plugin bug. See fxpio/composer-asset-plugin#321

OK, but how could it be solved?

I think that it is very common issue because famous packages are affected.

Could it be the right time to pass to npm ?

OK, but how could it be solved?

I updated my fxp/composer-asset-plugin (from 1.4.2 to 1.4.6) - it solved it.
