我在编译我使用的应用程序的可执行文件时遇到问题: - Python 3.3 - PyQT5 - Matplotlib
我尝试使用Cx_Freeze和这个setup.py:
import sys
from cx_Freeze import setup, Executable
includes = ['sys','PyQt5.QtCore','PyQt5.QtGui', 'PyQt5.QtWidgets','matplotlib']
excludes = []
packages = []
path = []
base = None
if sys.platform == 'win32':
base = 'Win32GUI'
options = {
'build_exe': {
"includes": includes,
"excludes": excludes,
"packages": packages,
"path": path
#'excludes': ['Tkinter'] # Sometimes a little finetuning is needed
}
}
executables = [Executable('pyqt5_matplotlib.py', base=base)]
setup(name='pyqt5_matplotlib',
version='0.1',
description='Sample PyQT5-matplotlib script',
executables=executables,
options=options
)
运行setup.py时,构建一个包含各种dll并创建了exe的文件夹,此时没有错误。 当运行由此创建的exe时,我收到此错误:

有人可以帮助我吗?
出于这个问题的目的,我将包括一个示例主脚本,在构建时重现错误:

答案 0 :(得分:3)
经过更深入的研究后,我做了以下几点:
backend: tkAgg
变为
backend: Agg
最后一个来源是ImportError: No module named backend_tkagg
此解决方案适用于带有Python3.3的Win 7 64位,适用于带有Matplotlib后端的单个窗口PyQT5。
