大家好。我很困惑为什么在运行我创建的用户脚本时，我一直收到“GM_registerMenuCommand未定义”的错误。我已经尝试在Firefox中使用Scriptish 1.0b9和最新版本的Greasemonkey。我甚至禁用了除Scriptish之外的所有插件，以查看是否存在冲突，但没有成功。
我在我的用户脚本中使用jQuery，使用Erik Vold的这个模板。在尝试这个模板之前，我把完全相同的代码块放在Joan Piedra提出的模板中，一切正常。不幸的是，Piedra的模板在Chrome中不起作用，考虑到Chrome日益增长的用户群，我认为这是必要的。引发错误的片段如下：

这是我正在尝试实现的用户脚本。如果有人对我为什么会出现错误有任何建议或想法，我很乐意听取！
