如何使用cx_Freeze冻结双模式（GUI和控制台）应用程序？ [英] How can I freeze a dual-mode (GUI and console) application using cx_Freeze?

问题描述

我已经开发了可以在GUI模式和控制台模式下运行的Python应用程序。如果指定了任何参数，它将在控制台模式下运行，否则将在GUI模式下运行。

I've developed a Python application that runs both in the GUI mode and the console mode. If any arguments are specified, it runs in a console mode else it runs in the GUI mode.

我设法使用cx_Freeze将其冻结。我在隐藏将随wxPython弹出的黑色控制台窗口时遇到了一些问题，因此我修改了 setup.py 脚本，如下所示：

I've managed to freeze this using cx_Freeze. I had some problems hiding the black console window that would pop up with wxPython and so I modified my setup.py script like this:

import sys

from cx_Freeze import setup, Executable

base = None
if sys.platform == "win32":
    base = "Win32GUI"

setup(
        name = "simple_PyQt4",
        version = "0.1",
        description = "Sample cx_Freeze PyQt4 script",
        executables = [Executable("PyQt4app.py", base = base)])

这很好用，但是现在当我尝试打开控制台并从那里运行可执行文件时，它什么也不输出。我没有收到任何错误或消息，因此cx_Feeze似乎正在将stdout重定向到其他地方。

This works fine but now when I try to open up my console and run the executable from there, it doesn't output anything. I don't get any errors or messages so it seems that cx_Feeze is redirecting the stdout somewhere else.

是否可以使其同时在两种模式下工作？似乎在任何地方都没有类似的记录。 ：（

Is is possible to get it to work with both mode? Nothing similar to this seems to be documented anywhere. :(

谢谢。

推荐答案

我在此页面上发现了这一点：

I found this bit on this page:

无控制台版本的提示：如果
您尝试打印任何内容，则
会显示一个讨厌的错误窗口，因为
stdout和stderr不存在（而
cx_freeze Win32gui.exe存根将
显示一个错误窗口）。当您希望程序成为
能够以GUI模式和
命令行模式运行。要安全地禁用
控制台输出，请在程序的
开头执行以下操作：

Tip for the console-less version: If you try to print anything, you will get a nasty error window, because stdout and stderr do not exist (and the cx_freeze Win32gui.exe stub will display an error Window). This is a pain when you want your program to be able to run in GUI mode and command-line mode. To safely disable console output, do as follows at the beginning of your program:

try:
    sys.stdout.write("\n")
    sys.stdout.flush()
except IOError:
    class dummyStream:
        ''' dummyStream behaves like a stream but does nothing. '''
        def __init__(self): pass
        def write(self,data): pass
        def read(self,data): pass
        def flush(self): pass
        def close(self): pass
    # and now redirect all default streams to this dummyStream:
    sys.stdout = dummyStream()
    sys.stderr = dummyStream()
    sys.stdin = dummyStream()
    sys.__stdout__ = dummyStream()
    sys.__stderr__ = dummyStream()
    sys.__stdin__ = dummyStream()

这样，如果程序以
-less控制台模式启动，如果代码包含打印语句，它甚至可以在
下工作。
如果以命令行模式运行，则
将照常打印出来。 （这是
，基本上就是我在webGobbler中所做的，
也是。）

This way, if the program starts in console-less mode, it will work even if the code contains print statements. And if run in command-line mode, it will print out as usual. (This is basically what I did in webGobbler, too.)
