Mac:应用程序退出，代码255，非法信号0X04

Question

我正在开发一个python应用程序，其中包含一个cephython3浏览器。应用程序正在正确编译，当我运行_应用程序副本，一切正常。但是当我用py2app打包它时，我得到了这些错误。到底是什么问题？我尝试搜索其他线程，但每个用户似乎都有不同的问题。在

注意：在我们的应用程序中，我们将cephython3的GPU标志设置为disable-gpu=true

在设置.py来自py2app：

from setuptools import setup

APP = ['Our_APP.py']
DATA_FILES = []
OPTIONS = {}

setup(
    app=APP,
    data_files=DATA_FILES,
    options={'py2app': OPTIONS},
    setup_requires=['py2app','cefpython3'],
)

请参见中如何处理退出代码255wxpython.py示例：

if MAC:
        # On Mac things work differently, other steps are required
        self.browser.CloseBrowser()
        self.clear_browser_references()
        self.Destroy()
        global g_count_windows
        g_count_windows -= 1
        if g_count_windows == 0:
            cef.Shutdown()
            wx.GetApp().ExitMainLoop()
            # Call _exit otherwise app exits with code 255 (Issue #162).
            # noinspection PyProtectedMember
            os._exit(0)
