只要您加载的JS文件正确，则可以使用 flowFactory 来创建一个流程实例。然后创建一个流对象，并用它来指流动。

  angular.module（属性）。控制器（'PropertiesController'，[
  '$范围'，
  '$ stateParams'，
  '$位置'，
  认证，
  '品牌'，
  应用程序，
  '属性'，
  flowFactory'，   功能（$范围，$ stateParams，$位置，认证，品牌​​，应用，性能，flowFactory）{$ scope.existingFlowObject = flowFactory.create（{
    目标：http://example.com/upload
}）;
.................................................. ..............
 

因此​​，尝试改变流量到 flowFactory 键，看看是否导致任何供应商的依赖问题。

I've been struggling trying to hook up this dependency (http://flowjs.github.io/ng-flow/) to my mean.js application. I'm thinking it's simply a naming problem.

The error I'm getting is: Error: [$injector:unpr] Unknown provider: flowProvider <- flow

I've tried 'flow', 'Flow', 'ngFlow', etc. Any help would be greatly appreciated.

    // Add a new vertical module
    var registerModule = function(moduleName, dependencies) {
        // Create angular module
        angular.module(moduleName, dependencies || []);

        // Add the module to the AngularJS configuration file
        angular.module(applicationModuleName).requires.push(moduleName);

        policies: 'modules/*/server/policies/*.js',

    }
};

So long as you loaded the js file correctly, you can use flowFactory to create a flow instance. Then create a flow object and use that to refer to flow.

angular.module('properties').controller('PropertiesController', [
  '$scope',
  '$stateParams',
  '$location',
  'Authentication',
  'Brands',
  'Applications',
  'Properties',
  'flowFactory',

   function($scope, $stateParams, $location, Authentication, Brands, Applications, Properties, flowFactory) {

$scope.existingFlowObject = flowFactory.create({
    target: 'http://example.com/upload'
});
................................................................

So try changing flow to flowFactory and see if that leads to any provider dependency issues.
