無法讀取屬性'getLineAndCharacterOfPosition'undefined

我被這個錯誤卡住了，有人可以幫我嗎？我剛剛升級到Angular2.4.3無法讀取屬性'getLineAndCharacterOfPosition'undefined

$ ng serve                                            [19:46:01]

我執行了'npm install'。所有依賴關係已成功下載 –

請提供您的代碼。 – Mistalis

太長了。我可能刪除了node_modules並再次嘗試npm install

它也可能是錯誤的配置。我忘了 –

我觸發這個稍微有點隱蔽的錯誤，當我不小心忘記返回來自我的一個組件的getter函數的值。

get gene() { 
    // return this._gene; 
}

這種情況發生時您修改tsconfig.app.json或tsconfig.json無效值。
