ng-annotate 错误与 Babel 和解构

Question

使用 Babel 转译为 ES6 时出现奇怪的错误，ng-annotate 不喜欢解构。我将我的源代码复制到在线 babel 编译器中，它工作正常。在我的 gulp 管道链中注释掉 ng-annotate 可以消除错误。删除文件中的 /* @ngAnnotate */ 注释并手动注入也不会改变任何东西。

Gulp 部分：

return gulp.src(config.scripts.app)
    .pipe(changed(config.dist + '/scripts'))
    .pipe(plumber())
    .pipe(annotate())

    // Filter out and transpile only .es6.js files
    .pipe(es6)
    .pipe(babel({
        presets: ['es2015'],
        plugins: ['extensible-destructuring'],
        comments: false
    }))
    .pipe(es6.restore)

    .pipe(concat('scripts.js'))
    .pipe(gulp.dest(config.dist + '/scripts'))

有问题的来源：

var [min, max] = values.map(val => +val);
// let/var doesn't make a difference.

ngModelCtrl.$modelValue = [min, max];

错误来自 ng-annotate 中的依赖项：

Error: StringMap expected string key
    at stringmap.set (/Users/macbookair/Places/app/places/frontend/node_modules/gulp-ng-annotate/node_modules/ng-annotate/node_modules/stringmap/stringmap.js:101:19)
    at Scope.add (/Users/macbookair/Places/app/places/frontend/node_modules/gulp-ng-annotate/node_modules/ng-annotate/build/es5/scope.js:102:17)
    at /Users/macbookair/Places/app/places/frontend/node_modules/gulp-ng-annotate/node_modules/ng-annotate/build/es5/scopetools.js:38:25
    at Array.forEach (native)
    .... more

stringmap.js 有问题的函数：

stringmap.prototype.set = function(key, value) {    
    if (typeof key !== "string") {
        throw new Error("StringMap expected string key");
    }
    if (key === "__proto__") {
        this.hasProto = true;
        this.proto = value;
    } else {
        this.obj[key] = value;
    }
};

在上面的函数returns中注销key和value this:

undefined { 
    kind: 'var', 
    node: { 
        type: 'ArrayPattern',
        start: 1178,
        end: 1188,
        loc: { start: [Object], end: [Object] },
        range: [ 1178, 1188 ],
        elements: [ [Object], [Object] ] 
    },
    from: 1215 
}

显然 key 参数未定义，但它为什么还要关心？

I have similar problem, I just simply changed the order in gulp pipe to: babel --> annotate. ng-annotate does not support new JS versions: github.com/olov/ng-annotate/issues/237
