錯誤：$ injector：unpr未知提供者：未知的提供者：bProvider < - b

我在AngularJS中編寫webapp，後端使用Grails。

在開發應用程序時，我可以使用grails run-app對其進行測試，但是在將應用程序部署到WAR文件並將其放入Tomcat服務器時，它不起作用。以下是錯誤（打印到控制檯JS）：http://errors.angularjs.org/1.4.8/ $噴油器/ unpr P0 = bProvider％20％3C-20B％

你可以看到一個真人版（在有限的時間）在這裏：http://test.neonorb.com/now/JKQXV

通常，該錯誤不會打印，並且您將看到正在發送的websocket消息（不在頁面上執行任何操作）。此外，直到採取行動請求該許可，紅色「釋放汽車」按鈕纔會顯示。

忽略頁面頂部的選項卡之類的東西，這不是去掉了一些測試代碼:)

下面源從生成的網站採取的，而不是源代碼：

您的代碼是在生產精縮，您需要將您的通話run改變這一點：

app.run(['$rootScope', function($rootScope) {
