我在这里遇到了一个非常不稳定的问题。菜单栏在运行时随机出现。我曾多次尝试在整个程序中重复使用 self.SetMenuBar(self.menuBarr) 但它似乎不会影响成功率。有谁知道任何类型的触发器的位置，它指示菜单栏是否已显示，以便我可以在需要时自动重新加载它？
或者，我在这里和这里看到了一些类似（但不同）的帖子，所以如果它与注意到的错误有关，那么有人知道我将如何调整黑客（在第一个链接中）以适用于简单的菜单栏吗？
在初始 wx.Frame 构造函数中，对 menu() 方法的调用已从创建序列的开头移至结尾，这也可能是有用的信息，但它也不影响菜单栏项的可靠性. 没有异常被调用。
提前感谢您提供的任何帮助！

更新 现在这开始变得非常奇怪。我已经通过以管理员权限执行程序解决了这个问题。我的任何脚本都不会删除 shell 命令，所以我完全不知道为什么会发生这种情况。
