它不会到达线c=创建控制点。为什么呢？请指导我删除此错误。

我不熟悉此“brisa”库。我认为，出于某种原因，ControlPoint构造函数正在使用sys.exit退出整个程序，或者正在调用一些等效的C代码

在命令行上运行程序，如下所示：

<brisa.core.reactors.glib2.GLib2Reactor object at 0x88c3e0c>
hello
hell

然后你应该能够看到它是否真的放弃了整个过程。如果它将您转储回>>>提示符，那么我不知道发生了什么。但是如果它完全退出Python，这意味着ControlPoint构造函数正在退出。

我建议您打印更多有用的注释，例如完成的create\u control\u point和内部的create\u control\u point，而不是使用不同数量的ls在Hello上的不同变体。是的……您说得对，ControlPoint构造函数正在退出。我该如何纠正它？你可以在这里看到布里萨图书馆：请给我提建议。我简单地看了一下那些文件。除了ControlPoint构造函数使用大量代码调用许多其他构造函数之外，没有任何明显的东西浮现在脑海中。任何一个都可能是原因。我会寻找对C代码的调用；这很可能是退出——也许某些C代码在出现错误的情况下退出，而不是引发适当的Python异常。
