Typescriptコンパイラが突然エラーを生成し始めました

Question

私はAngular 2プロジェクトに取り組んでいます。突然、typescriptコンパイラを試してみるとたくさんのエラーが出るようになりました。誰でもどこから検索を始めるべきかアドバイスできますか？私は故意に何か基本的なものを変更していないし、リポジトリから新鮮なコピーをクローンしても、エラーは持続する。エラーは次のとおりです。

Answer 1

ノードタイプが2か所あるようです。

node_modules/@types/node/index.d.ts

タイピング/グローバル/ノード/ index.d.ts

Answer 2

前に述べたように、あなたはtypescript2を使用することにより（混合@typesを持っているように見えます）を入力する。私がtypescript 2.xにアップグレードしたときと同じように。私はまったく同じ種類のエラーを持っています。 。 はI単に "のTSconfigでcompilerOptionsでtypes": []を型宣言を追加することによって解決私はここでより詳細にこれを記載している： https://stackoverflow.com/a/40627265/333150

これは基本的に@types位置からタイプのいずれかを含み、そしてのみ使用されませんあなたのタイピングの宣言。

Answer 3

typings.jsonファイルを削除するには、この問題を解決します。アンギュラクイックスタートプロジェクトの以前のバージョンでは、このファイルを含め

。しかし、角度の最新バージョンにアップグレードしようとすると、私が見つかりました。このファイルはクイックスタートの一部ではなく、削除されましたthis commitで編集。クイックスタートのアップデートは、もともとプロジェクトをそのコードから外してしまった場合に役立ちます。
