Javascript AngularJS、Node.js、节点模块'；幻影'；。。。注入错误，angularjs试图加载我的指令+；后缀

当我加载AngularJS页面时，它加载得很好。没有控制台错误。内容如预期所示

当我从另一个应用程序加载同一页面时，使用节点模块“phantom”失败，出现错误：

错误：[$injector:unpr]

未知提供者：WidgetsProvider自我回答：

最终我遇到了一个文件包含问题。这在这一点上是无关紧要的。然而，我确实认为，在我的旅程中有三点值得一提

Unknown provider: WidgetsProvider <- Widgets <- dashboardWeightTableWidgetDirective

未知提供程序：WidgetsProvider您可能有时间问题。看看你的承诺链。您从setTimeout返回，但该值被丢弃。你需要回复一个承诺并在callbackAluan Haddad中解决它。。。使用我添加到问题中的代码：奇怪的指令错误立即弹出。然后，20秒后，我的控制台打印出来，一个空的网页到达。这表明错误发生在page.open调用中。你是否仍然怀疑承诺链、时机问题？这是一种明显的可能性。不管返回语句的存在与否，它都会以某种方式指示错误。它没有做它看起来像在做的事情。
。然后（（）=>新承诺（resolve=>{setTimeout（resolve）；}））。然后（（）=>_page.render（conf.options.filePath）。然后（（）=>{page.close（）；}）
我还意识到了另一件事：你的外部承诺构造函数调用被破坏了。你既不解决也不拒绝它，
返回是一个错误。
