AngularJS將多個服務模塊注入控制器時出現未知提供程序錯誤

Question

我有一個模塊'moduleA'，它有兩個服務，一個（serviceB）取決於另一個（serviceA）。我試圖將serviceB注入屬於不同模塊'foo'的控制器，但是我得到了未知的提供者錯誤。下面是我的代碼：

module.js

angular.module('moduleA', []); 

工廠a.js

angular 
.module('moduleA') 
.factory('factoryA', factoryA); 

factoryA.$inject = ['$q', '$log', '$timeout']; 

function factoryA($q, $log, $timeout) { 
//Do Stuff 
} 

工廠b.js

angular 
.module('moduleA') 
.factory('factoryB', factoryB); 

factoryB.$inject = ['factoryA']; 

function factoryB(factoryA) { 
//Do Stuff 
} 

富-controller.js

angular.module('foo', ['moduleA']) 
     .controller('fooController', ['factoryB', function(factoryB){ 
//Do Stuff 
}) 

錯誤控制檯：

這聽起來微不足道，但你有你的工廠b.js文件在您的項目？

我認爲你應該修復下面顯示的代碼。除此之外，一切看起來都很好。

function factoryA($q, $log, $timeout) { //remove the '' 
//Do Stuff 
}
