我正在尝试用我的应用程序实现角度图表。我凉亭安装了 angular-chart.js 并将 chart.js 列为依赖项。但是，当我加载我的页面时，我收到以下错误：
angular.js:68 Uncaught Error: [$injector:modulerr] Failed to instantiate module app due to:
Error: [$injector:modulerr] Failed to instantiate module chart.js due to:
Error: [$injector:nomod] Module 'chart.js' is not available! You either misspelled the module name or forgot to load it. If registering a module ensure that you specify the dependencies as the second argument.
我的问题是：如何让这个错误消失？我已经验证图表是在角度图表之前加载的，但我无法让这个错误消失。

define('app', [], function() {
return app;
});
