示例webpack angular4應用程序拋出錯誤

我想創建一個示例angular-webpack應用程序在https://angular.io/docs/ts/latest/guide/webpack.html中指定，但它拋出了大約26個錯誤。即使在將打字稿版本更改爲「〜2.2.1」之後，這些錯誤即將到來。示例webpack angular4應用程序拋出錯誤

任何人都可以幫助我解決這些錯誤嗎？

的TSXXX錯誤似乎肯定涉及到使用打字稿之前的2.1版本，例如here和here解釋。

請驗證：

在你聲明的打字稿版本的package.json文件（「打字稿」：「〜2.2.1」將是OK）
您有效地利用到打字稿版本編譯該項目。您可以從npm start命令的輸出中驗證。你應該看到類似[at-loader] Using [email protected] from typescript and "tsconfig.json" from /usr/src/ng2-projects/angular-webpack/src/tsconfig.json; [email protected]部分將顯示用於編譯的版本。

TS2304錯誤似乎與所需類型聲明的配置錯誤有關。請參閱here瞭解如何配置它們。
