当我尝试将braintree-angular包含到我的gulp-angular项目中时，我收到以下错误：
Uncaught Error: [$injector:modulerr] Failed to instantiate module notecards due to:
Error: [$injector:modulerr] Failed to instantiate module braintree-angular due to:
Error: [$injector:nomod] Module 'braintree-angular' 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.
我经常遇到在gulp-angular项目中加载新安装模块的问题，我相信它来自对gulp如何工作的普遍缺乏理解。该项目的吞咽部分由同事设置。如果有人能够解释为什么我会继续看到这样的问题，那将非常感谢！
我检查过以下内容：

Gulp只是一个（非常强大的）任务选手，简单明了。它会做你自己可以做的事情，但你没有时间;）
节点模块与Angular模块不同。节点模块具有广泛的范围，用于在Node.js平台中运行通用代码。也就是说，Javascript在典型的Web浏览器设置之外运行。例如桌面应用程序，贷款计算器，Web服务器，聊天程序等
但是，许多Node模块专门用于Angular并具有Bower计数器部分。实际上，Bower软件包直接包含在您的网页中：
<script src="./bower_components/path/to/script.js" type="text/javascript"></script>
为什么Web模块都有Node模块和Bower包，您可能会问？这是因为像Browserify和Webpack这样的捆绑包可以让您在网页中实际使用Node模块。您的项目似乎没有为打包程序设置。
您希望为您的模块获取已编译的js（理想情况下，通过修改gulpfile来编译和/或从节点模块的文件夹中连接正确的JS文件）或使用Bower下载已编译的JS，并修改gulp文件以将其包含在连接过程中。
构成项目的Gulp流程有多个文件。寻找＆＃39; build＆＃39;其中一个文件中的任务。它应该包括有关如何构建供应商JS文件的详细信息。您想修改它以便包含braintree-angular的JS文件的路径（如果存在）

好的，解决这个非常具体的问题是从node_modules中删除braintree-angular并通过bower安装它。我还需要将版本锁定到v1.3.0。我不确定为什么这修好了，所以解释会很棒：）
答案 2 :(得分：0)
Gulp与Angular模块无关。从您发布的任务开始，它仅用于本地主机开发，而不是用于任何依赖注入。
您的问题可能来自不要求依赖模块。 app.module看起来应该是这样的。
angular.module('app', [
'angular-svg-round-progress'
]);
并确保在应用程序实例化失败之前加载模块。
