tinymce正在从云中加载脚本

Question

如何防止tinymce从云中加载内容，而是从本地路径中加载它们？

tinymce.init({
    selector:'textarea',theme: "modern",
    height: 400,
    document_base_url : "http://my_domain.com/",
    relative_urls : true,
external_plugins: {
    'responsivefilemanager': '/assets/js/plugins/responsivefilemanager/plugin.min.js',
    'filemanager': '/assets/js/plugins/filemanager/plugin.min.js',
},
etc...

但是随后在控制台中，我看到了：
