Q&ALaravel＋Vue環境で eslintを入れているのですが、eslint実行時に
error 'Vue' is not defined
が出てしまいます。（ターミナルにエラーは出るものの、Vueファイルのコンパイル自体はできる）
原因がわからないので、教えていただけると幸いです。
各種ファイルの設定以下の通りです。

window.Vue = require('vue');をconst Vue = require('vue');に変更すればエラーが消えるかと思います
eslint:recommendedではstrictモードが有効になっているものとして解析します
これによりnew Vueとしている箇所で参照されるものがwindow.Vueではなく、ファイル内の変数Vueとなるため未定義のエラーが出力されているものと思います
