cx_freeze 和 pythonnet clr 的问题

Question

我正在尝试使用 pythonnet clr 和 cx_freeze 构建一个应用程序，我已经使用 pyinstaller 成功构建了它，所以我知道它可以工作，但是当我使用 cx_freeze 并尝试启动 .exe 时收到以下错误：

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.get_data_path(), "matplotlib.figure"),
                                       (matplotlib.get_data_path(), "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，任何见解将不胜感激

Answer 1

由于我很难让 pythonnet 与 cx_freeze 一起工作，我将我的应用程序分成两个应用程序。我使用 PyInstaller 将 pythonnet 应用程序打包到从主应用程序调用的可执行文件中。然后我使用 cx_freeze 将主应用程序打包成可执行文件，并将两个应用程序打包成我所追求的 msi 包。

让 cx_freeze 与 pythonnet 一起工作会很棒，但这是一个不需要太多努力的解决方法
