sass-loaderでdart-sass

Ruby Sass is deprecated and will be unmaintained as of 26 March 2019.
らしいので、

sass-loaderでdart-sassを使おうとしてます。

しかし、インストールするときに

$ npm i webpack webpack-cli sass sass-loader style-lopader fibers --save-dev

とコマンドするところを

$ npm i webpack-cli sass sass-loader style-lopader fibers --save-dev

とwedpackが抜けた状態でコマンドを打ってしまいました。
どうアンインストールするべきなのか、などをご教授いただきたいです。

以下、エラー文です。
