cx_freeze和pythonnet clr的问题

问题描述

我正在尝试使用pythonnet clr和cx_freeze构建应用程序，我已经成功地使用pyinstaller构建了它，因此我知道它可以正常工作，但是当我使用cx_freeze并尝试启动.exe时，会收到以下错误消息：

Unhandled Exception: System.Reflection.TargetInvocationException: Exception has been thrown by the 
target of an invocation. ---> System.ArgumentNullException: Value cannot be null.

   at clrModule.PyInit_clr()

我的setup.py如下：

from cx_Freeze import setup,Executable
import sys
import matplotlib
import site
from mypackage import version

mpl_toolkits = site.getsitepackages()[1] + '/mpl_toolkits'


def getTargetName():
    """OS specific name for application"""
    app_name = "myapp"
    if sys.platform.startswith('linux'):
        return app_name
    elif sys.platform.startswith('win'):
        return app_name + ".exe"
    else:
        return app_name + ".dmg"


# Dependencies are automatically detected,but it might need fine tuning.
build_exe_options = {"packages": ["os",'sys','pyqt5','serial.win32','numpy','pubsub','mypackage','clr'],"includes": [],"include_files": [(matplotlib.get_data_path(),"mpl-data"),(matplotlib.get_data_path(),"matplotlib.backends.backend_qt5agg"),"matplotlib.figure"),"matplotlib.dates"),(mpl_toolkits,"mpl_toolkits")],"excludes": ["tkinter","matplotlib.tests","numpy.random._examples"]}

# GUI applications require a different base on Windows (the default is for a console application).
base = None
if sys.platform == "win32":
    base = "Win32GUI"

setup(name="myapp",version=version.VERSION,description="application",options={"build_exe": build_exe_options},executables=[Executable("mypackage/main.py",icon="mypackage/logo.ico",shortcutName="my app",shortcutDir="DesktopFolder",targetName=getTargetName(),base=base)])

在添加pythonnet clr组件之前，我已经成功构建了应用程序，希望您能对此有所了解

解决方法

由于难以获得pythonnet与cx_freeze的配合，我将应用程序分为两个应用程序。我使用PyInstaller将pythonnet应用程序打包为一个从主应用程序调用的可执行文件。然后，我使用cx_freeze将主应用程序打包为可执行文件，然后将两个应用程序打包为msi软件包。

让cx_freeze与pythonnet一起使用会很棒，但这是一种解决方法，不需要太多的努力
