node.js - 错误 : uncaughtException: require(. ..).invokeRolesPolicies 不是函数

Question

我正在使用 MEAN.JS 开发一个 Web 应用程序，但由于某种原因，在我做了一些更改(主要是将新模块复制并粘贴到应用程序中)后，我看到了如下错误:

error: uncaughtException: require(...).invokeRolesPolicies is not a function

我不知道为什么会发生这种情况，有人知道如何解决这个问题吗？

这是完整的错误消息:

实际上，这与错误命名的文件无关。

您需要确保在策略文件中定义了 invokeRolesPolicies 函数。最低要求是:

'use strict';

var acl = require('acl');
acl = new acl(new acl.memoryBackend());

exports.invokeRolesPolicies = function () {};

原因是mean.js中定义的express.js库假设它已设置，并尝试调用它，因此出现错误。
