python - Mac : Application exited with code 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 CEFPython3 浏览器。该应用程序已正确编译，当我运行 our_app.py 时，一切正常。但是当我用 py2app 打包它时，我收到这些错误。到底是什么问题呢？我尝试搜索其他线程，但每个用户似乎都有不同的问题。

注意:在我们的应用中，我们将 CEFPython3 的 GPU 标志设置为 disable-gpu=true

来自 py2app 的 setup.py :

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'],
)

查看 wxpython.py 示例中如何处理退出代码 255:

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)
