Bri*_*den 8 javascript node.js angularjs bundling-and-minification
我正在使用Grunt并执行cmd"grunt build"来创建包含AngularJS应用程序的分发文件夹.
作为一个独立的我的应用程序工作正常.一旦我为应用程序创建了一个分发版,应用程序就会很快崩溃.
我在F12 Tools Console中看到的是:
达到10 $ digest()次迭代.中止!
我怀疑我的.tmp目录中名为vendor.js的文件,并且由于控制器依赖注入变量错误地将注入的控制器参数(例如"$ scope")注入"a",因此无法正确缩小,uglify和/或连接此文件,即使我正在使用ngAnnotate.
看看我正在使用UglifyJs并在Uglify和Concat之前调用ngAnnotate但是我无法从useMinPrepare中删除UglifyJs,或者我还有其他错误,例如甚至没有在我的dist目录中创建脚本目录:
useminPrepare: {
html: '<%= yeoman.app %>/index.html',
options: {
dest: '<%= yeoman.dist %>',
flow: {
html: {
steps: {
js: ['concat', 'uglifyjs'],
css: ['cssmin']
},
post: {}
}
}
}
},
我在我的GruntJs文件中设置了mangle = false但是我怀疑useMinPrepare js: ['concat', 'uglifyjs']在调用ngAnnotate之前更改执行顺序并运行uglify useMin,即使我调用useMin之后也是如此ngAnnotate.
我是Grunt的新手,这个应用程序已经从另一个开发人员传递给我.
我发现这篇文章对我来说并不完全有意义,也不是一个似乎适用于我的Gruntfile.js的代码更改,但我想也许我正在做些什么:
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:

所以我走上了错误的道路，认为 Uglify、concat 或 minification 的平滑是错误的。
该错误不会发生grunt serve，但仅在创建 dist 包后发生grunt build:dist
因此，在我创建 dist 包之前，我的 Angular 应用程序确实可以正常工作，这在某种意义上是一种欺骗。
问题出在我身上，我最初<ng-include src="'scripts/navigation/navigationMobile.html'"></ng-include>在 Index.html 文件中有一个元素。
在某些时候，我创建了一个<my-nav></my-nav>使用相同内容的自定义元素指令，但我忘记从要替换的Index.html 中templateUrl = scripts/navigation/navigationMobile.html删除该元素。<ng-include src="'scripts/navigation/navigationMobile.html'"></ng-include><my-nav></my-nav>
不管出于什么原因，$digest() 迭代达到了 10 次。流产！仅在运行grunt build和创建缩小的、丑化的vendor.js 文件后发生，在仅使用开发和测试时不会发生grunt serve，但我不知道该错误仅在grunt build.
也许有人可以回答这个问题。
