エラーTS1259：module '"./node_modules/@types/express/index"' 'esmoduleInterop'フラグを使用してデフォルトインポートできます。
私はプロジェクトにエクスプレスをインポートしようとしていて開発の途中で動作を停止しました、私は構成をリグニングしました。それを作動させることはできません、モジュールをインポートすることはできません。
npx tsc src/server.ts

_編集2：変更されたTSCONFIG.JSON "allowSyntheticDefaultImports": trueはまだ同じエラーを示しています
編集3：githubリンク：[削除]
問題は./server./server2はちょうどうまく機能しています。同じ設定.
Edit4：解決しました
Github Repoによると、.server2には.server2にはTSCONFIGファイルがありません。 TSCONFIGファイルが./server2のように./server/tsconfig.jsonを./server/tsconfig.jsonに移動する必要があります（TSCONFIGをコピーしないと言ったことが言っています）.. Matt Oestreich）
