我正在使用 Grunt 并执行命令“grunt build”来创建一个包含 AngularJS 应用程序的分发文件夹。
作为独立应用，我的应用运行良好。一旦我为该应用程序创建了一个分发版，该应用程序就开始很快崩溃。
我在 F12 工具控制台中看到的是:
达到 10 次 $digest() 迭代。中止!
我怀疑我的 .tmp 目录中有一个名为 vendor.js 的文件，并且由于 Controller 依赖注入(inject)变量将注入(inject)的 Controller 参数(如“$scope”转换为“a”)而无法正确缩小、丑化和/或连接此文件例如，即使我使用的是 ngAnnotate。
看到我正在使用 UglifyJs 并在 Uglify 和 Concat 之前调用 ngAnnotate 但我无法从 useMinPrepare 中删除 UglifyJs 或者我有其他错误，例如脚本目录甚至没有在我的 dist 目录中创建:
useminPrepare: {
html: '<%= yeoman.app %>/index.html',
options: {
dest: '<%= yeoman.dist %>',
flow: {
html: {
steps: {
js: ['concat', 'uglifyjs'],
css: ['cssmin']
},
post: {}
}
}
}
},
我在我的 GruntJs 文件中设置 mangle = false 但我怀疑 useMinPrepare js: ['concat', 'uglifyjs'] 更改执行顺序并在 ngAnnotate 可以运行之前运行 uglify useMin 被调用，即使我在 ngAnnotate 之后调用了 useMin。
我是 Grunt 的新手，这个应用是从另一个开发者那里传给我的。
我发现这篇文章对我来说并不完全有意义，也不是似乎适用于我的 Gruntfile.js 的代码更改，但我想也许我正在做一些事情:
https://github.com/DaftMonk/generator-angular-fullstack/issues/164
我已将 Uglify mangle 选项设置为 false，但它没有解决我的问题。
这是我的 Gruntfile.js 代码:

最佳答案
所以我走错了路，认为 Uglify 或 concat 或缩小的平滑是错误的。
grunt serve 没有发生错误但仅在使用 grunt build:dist 创建 dist 包后才发生
所以从某种意义上说，在我创建 dist 包之前，我的 Angular 应用程序确实可以正常工作，这是一种欺骗。
问题对我来说，我最初有一个 <ng-include src="'scripts/navigation/navigationMobile.html'"></ng-include>我的 Index.html 文件中的元素。
在某些时候我创建了一个自定义元素指令 <my-nav></my-nav>使用相同的 templateUrl = scripts/navigation/navigationMobile.html但我忘了删除 <ng-include src="'scripts/navigation/navigationMobile.html'"></ng-include>我的 Index.html 中的元素 <my-nav></my-nav>旨在取代。
无论出于何种原因，达到了 10 $digest() 迭代。中止! 仅在运行 grunt build 后发生并创建缩小的 Uglified vendor.js 文件，在使用 grunt serve 进行开发和测试时不会发生这种情况但我不知道错误仅在 grunt build 之后出现的确切原因.
也许有人可以回答这个问题。
