当我运行这个BOOMR.subscribe函数时，它没有被执行。我不明白为什么？我已经使用link包含了Boomerang文件夹

您使用的Boomerang没有任何插件，因此无法运行。自述文件顶部附近有以下文本：

你必须包括至少一个插件，它不必是rt，否则灯塔将永远不会被调用

你们有并没有用必要的插件构建回飞棒？让我们看看你的boomerang.js文件是什么样子的。这是我添加的boomerang.js插件，它位于boomerang的plugins文件夹中，即bw.js，但现在我在它上面调用init方法，即BOOMR.init。上面写着未捕获的参考错误，Boomer对象未初始化我认为你应该把这个问题转移到boomerang问题列表中：我得到的数据变化太大了，即在同一页上反复计算的带宽，这与boomerang结果有很大的不同。当我加载回飞棒页面时，它给出了大约5917kbps±59%的带宽，我的结果给出了从6006kbytes/sec到277238kbytes/sec的各种范围。你能告诉我为什么会有这么大范围的结果以及错误在哪里吗？这是正常的，因为带宽测量取决于测试运行时网络上发生的一切。此外，yahoo.github.io上的页面已经过时4年了。您应该使用位于的网站
