我在OS X Yosemite上使用Python 3.4.3，Pyqt4和其他一些附加功能（其中包括Poppler）制作了一个应用程序。
我正在使用cx_freeze生成一个有效的.app文件，最终生成一个有效的msi文件。在使用build命令构建它之后，我一直在测试应用程序正常工作，如“python3 setup.py build”中所示。这一切都很好，没有意外的崩溃。 继续使用“python3 setup.py bdist_dmg”打包它。打开dmg文件/ app文件，它们立即崩溃，发出此错误：

有更多的负载，但我不确定有多大相关性。这是我的setup.py文件：
from cx_Freeze import setup, Executable
import sys
import os
base = None
if sys.platform == "win32":
base = "Win32GUI"
zips = ["implementation/primaries/GUI/designer_files",
"implementation/primaries/GUI/themes", "implementation/primaries/GUI/images",
"implementation/primaries/scripts"]
build_exe_options = {"packages": ["os"], "excludes": ["tkinter"],

)
不确定问题是什么，我看到其他一些人有类似的问题，但他们似乎是旧版本的Python或旧版本的OS X，修复程序并没有解决我的问题。任何有关如何进行的建议将不胜感激。
答案 0 :(得分：1)
找到一种更好的调试方法：右键单击app文件，＆＃34;查看包内容＆＃34;，MacOS＆gt;选择与setup.py中给出的文件同名的可执行文件（对我来说这是主要的）。
我得到的错误：
QWidget: Must construct a QApplication before a QPaintDevice
我通过初始化我的Application对象，然后初始化我的主窗口对象，然后显示主窗口，然后调用设置窗口的加载方法来解决这个问题。我最初在构造函数中做了那个部分，由于某种原因给出了问题。 我现在遇到打开/关闭窗口以及关闭时打开其他窗口的问题，但这可能是谷歌搜索的另一个问题或会话的最佳选择。

看起来您可能缺少QtGui dll文件。我没有在OS X上使用cx_freeze进行打包，但通常你必须将（QtCore，QtGui）dll放入工作目录。您是否在设置中尝试了QtGui的其他示例？
