內存中的角度Web API內部服務器錯誤

Question

在Angular的“英雄之旅”教程中，我已經邁出了最新一步。 使用angular-in-memory-web-api后，屏幕上沒有任何數據。 沒有編譯錯誤，但是在瀏覽器的控制台中我得到了：

一切都與本教程中的完全相同。 我尚未找到任何解決方案，因此為什么我必須自己問這個問題。

這是我的package.json的樣子：

Answer 1

這是由於angular-in-memory-web-api版本0.6.0中的更改所致。 解決您的問題的好方法：

npm install angular-in-memory-web-api@0.5.4 --save

如果下載完整的教程示例，則package.json具有：

"angular-in-memory-web-api": "~0.5.0",

因此0.6.0不在范圍內。
