程序退出结束时pyobjc和wx崩溃

Question

与此问题wxPython + PyObjC causes app to crash at the end类似，但代码中包含更多多余的代码。

我有以下两个代码示例，后者崩溃前运行正常。

代码的唯一区别是导入的顺序。

此代码运行良好。

import time

# note that the line is before this is so the code does work this is the only
# change that seems to matter
# need the following line to be AFTER wx import otherwise runs fine
import objc # or import Foundation or probably any objc library

import wx



# need the following line
app = wx.App(redirect=False)

# sleep shows it is ONLY when the code finally ends not before
time.sleep(3)
# you don't even need the MainLoop call

当程序停止运行时，此代码会运行段错误。

import time

import wx
# need this line to be AFTER wx import otherwise runs fine
import objc # or import Foundation or probably any objc library


# need the following line
app = wx.App(redirect=False)

# sleep shows it is ONLY when the code finally ends not before
time.sleep(3)
# you don't even need the MainLoop call

如何复制

1. 确保已安装pyobjc，您可以导入objc
2. 确保安装了wxPython（似乎2.9和3.0都有效）
3. 运行命令python 文件

临时解决方案

注意：这仅适用于特定情况，并且仍然是一个黑客，所以不应该一直使用。

这似乎有效，但令人反感，因为它只修复错误而不是下划线代码问题

确保在导入wx之前导入objc 或导入任何库（例如我在安装之前必须先使用双绞网库）与wx一起工作的反应堆（因此它导入了wx））。
