Webpack 4+babel 7のbabelrcファイル構成babel 7は導入方式が変わったため、古い:“env”、新しい:“@babel/preset-env”、自分で比較を観察することができます.重点的に言えば、antdとantd-mobileの導入は、以前とは書き方が異なり、前の配列に複数のオブジェクトを導入することができます.現在、1つの配列は1つしか導入されていません.配列の3番目の要素はnameで書かなければなりません.[“import”, { “libraryName”: “antd”, “libraryDirectory”: “lib”, “style”: “css”}, “ant” ],
