當使用類裝飾器時需要未捕獲的反射元數據填充

在嘗試使用typescript和npm運行我的Angular2應用程序時，我在標題中出現錯誤。正如在類似的話題中所說，我嘗試了「導入」反射元數據「;」但它沒有工作。當使用類裝飾器時需要未捕獲的反射元數據填充

這是我的package.json文件的依賴性：

"reflect-metadata": "0.1.3",

預先感謝您的時間

PS：這件事發生後，我從RC4升級我的應用程序RC5

您可以創建一個plunker重現它有點不同？ – candidJ

你解決了嗎？我有同樣的問題，我也從rc4升級到rc5（在這裏使用webpack） – Manatax

控制檯中應該有錯誤，說明爲什麼reflect-metadata未加載。

0.1.3存在的問題是它具有conditional dependencies，可能被模塊化系統（SystemJS，Webpack等）錯誤地包含在內。如果腳本以正常的方式加載這不會發生，

<script src="https://npmcdn.com/[email protected]"></script>

後來包的版本應該被用來使用reflect-metadata與模塊化系統，0.1.8可在這一刻。

我添加了錯誤的詳細信息。請檢查它，並幫助我用你友善的建議來解決它 –

它關係到你的構建而不是其他任何東西。你不需要（'vendor'）'模塊。這是一個應用polyfills和一切。 – estus

我得到了angular 4.1.3與cli構建當我升級我的swagger生成客戶端代碼休息端點（swagger編輯器2.2.3）相同的問題。

我已經添加了reflect-metadata，它爲我工作。任何人在angular 4之後面臨問題並且有cli可能會有所幫助。

你在哪裏添加了它？ – untitled

將其添加到您的package.json文件中，該文件將在您的項目相關連接中安裝反射元數據。 –
