我正在尝试编译一些 Python 3.3代码使用 cx_freeze并在编译后得到 test.exe文件将创建无限数量的程序实例，导致我的 Windows 7 系统变得不稳定。它在 Python 中运行时按预期工作，但一旦编译就会导致问题。这是我在主脚本中的导入:
import sys
from multiprocessing import Pool, Queue
from threading import Thread
from time import sleep, time
from inspect import getmembers
from PyQt5 import QtWidgets, QtCore, QtGui
from main_ui import Ui_MainWindow # Generated UI from pyuic, imports
# QtWidgets, QtCore, and QtGui
from devices import Device1, Device2 # Both are serial.Serial objects
setup.py脚本:import sys
from cx_Freeze import setup, Executable
product_name = 'Product Name'
path_platforms = ("C:\Python33\Lib\site-packages\PyQt5\plugins\platforms\qwindows.dll",
"platforms\qwindows.dll")
includes = ['PyQt5.QtWidgets', 'PyQt5.QtCore', 'PyQt5.QtGui']
include_files = [path_platforms]
excludes = ['_gtkagg', '_tkagg', 'bsddb', 'curses', 'email', 'pywin.debugger',
'pywin.debugger.dbgcon', 'pywin.dialogs', 'tcl',
'Tkconstants', 'Tkinter']
packages = ['os']
path = []
bdist_msi_options = {'add_to_path': False}
build_exe_options = {'includes': includes,
'include_files': include_files,
'excludes': excludes,
'packages': packages,
'path': path,
'silent': True}
base = None
if sys.platform == 'win32':
base = 'Win32GUI'
exe = Executable(script='main.pyw',
base=base,
targetName='test.exe')
setup(name=product_name,
version='1.0',
description='The Test Program',
executables=[exe],
options = {'bdist_msi': bdist_msi_options, 'build_exe': build_exe_options})
当我运行时
python setup.py build ，出现以下错误:Missing modules:
? System imported from serial.serialcli
? TERMIOS imported from serial.serialposix
? __main__ imported from bdb
? _gestalt imported from platform
? _posixsubprocess imported from subprocess
? clr imported from serial.serialcli
尽管有这些错误，它仍然会生成
test.exe文件。当我执行它时，它会生成看似无限数量的窗口，停止它的唯一方法是硬重置计算机。同样，主脚本在 Python 下运行得很好，但一旦编译就失败了。任何帮助将不胜感激!编辑:根据要求，这是我的主要脚本:

最佳答案
在其他任何事情之前，您需要将以下代码添加到您的 main 中:
from multiprocessing import freeze_support
freeze_support()
