jest + vuejs + vuetifyの予期しない識別子

私は答えを高低で検索しました。 .babelrcの問題だと思いますが、うまくいく答えが見つかりません。

アプリは問題なく動作しますが、私が知ったように、JestとRollupはどちらも実際には.babelrcに依存しています。他の考えられる原因はリーフレットです。私が作成してテストしたすべてのコンポーネントのうち、Leafletとvue2-leafletを含むコンポーネントだけがこの問題を抱えているようです。私がマッピングアプリに取り組んでいることを考えると、これは私にとって重要です。

何も証明できないので、ここに投稿します。そして、同様の問題を見た他の多くの人々がいます。

デフォルトでは、Jest node_modulesで何も変換しません （vuetifyパッケージが存在する場所）ですが、実際には、構成済みのvuetifyを実行するために必要です。 babel-jestは、importsがトランスパイルできるように変換します。これを行うには、jest.config.jsでこの構成を使用します。

module.exports = {
  transformIgnorePatterns: [
    '<rootDir>/node_modules/(?!vuetify)'
  ],
  ...
}
