javascript - 捆绑的 JS 库，例如angular, jQuery, lodash 在 eval 抛出 "require is not defined"之后

Question

我正在使用 grunt-contrib-concat 捆绑不同的 JS 库，如下所示:

dist7: {
    src: [
        'lib/jquery/dist/jquery.js',
        'lib/ng1.6/angular-animate/angular-animate.js',
        'lib/ng1.6/angular-aria/angular-aria.js',
        'lib/ng1.6/angular-messages/angular-messages.js',
        'lib/api-check/dist/api-check.js',
        'lib/angular-formly/dist/formly.js',
        'lib/ng1.6/angular-sanitize/angular-sanitize.js',
        'lib/angular-ui-router/release/angular-ui-router.js',
        'lib/lodash/lodash.js',
        'lib/angularjs-toaster/toaster.js',
        'lib/moment/min/moment-with-locales.js',
        'lib/eventie/eventie.js',
        'lib/wolfy87-eventemitter/EventEmitter.js',
        'lib/imagesloaded/imagesloaded.js',
        'lib/desandro-matches-selector/matches-selector.js',
        'lib/doc-ready/doc-ready.js',
        'lib/fizzy-ui-utils/utils.js',
        'lib/desandro-get-style-property/get-style-property.js',
        'lib/get-size/get-size.js',
        'lib/outlayer/item.js',
        'lib/outlayer/outlayer.js',
        'lib/masonry-layout/masonry.js'],
    dest: 'dist/js/my-dependencies.js'
}

当我在脚本标签中添加 dist/js/my-dependencies.js 时，它起作用了。

但是当我执行一个获取请求时，我会像下面这样进行评估:

fetch('dist/js/my-dependencies.js', {method: 'GET'})
    .then(response => response.text()))).then(scr => {
        eval(scr)
    });

出现以下错误:

Err in evaling:  /cuicui/scripts/js/my-dependencies.js  With err: 
 ReferenceError: require is not defined
    at installedModules (eval at <anonymous> (cd.component.js:12), <anonymous>:1:93)
    at eval (eval at <anonymous> (cd.component.js:12), <anonymous>:1:554)
    at cd.component.js:12
    at Array.forEach (<anonymous>)
    at cd.component.js:12
    at <anonymous>

问题:您的一个依赖项在文件的顶部(概率)有一个 require('someLib')。

如何查找:遍历每个库并搜索关键字 require

为什么 eval 会失败？eval() 在窗口上而不是在节点中。因此，它不知道如何处理该关键字。我会建议找到所有库的预压缩版本，而不是使用库源。
