python - 错误：从 python3 exe 子进程运行 Maya 时，“模块使用 python37.dll 与此版本的 Python 冲突”

Question

我无法从捆绑的 .exe 程序 (Python 37) 启动 Maya 2020 (Python 27)。我使用 pyinstaller 来捆绑 exe。

如果我从 IDE 启动我的工具，它会很好地启动 Maya。当我从 .exe 启动工具时，模块中的几个 Maya python 出现此错误：

# Error: line 1: ImportError: file C:\Program Files\Autodesk\Maya2020\bin\python27.zip\ctypes\__init__.py line 10: Module use of python37.dll conflicts with this version of Python. # 

我已经尝试了这篇文章中的建议，但我不确定我做错了什么。

• 我在我的工具中使用 PySide2 和 Python37
• 我的全局 PATH 中没有任何版本的 Python（我正在使用虚拟环境）
• 我尝试在 subprocess.Popen 启动期间添加 sys.insert 或创建 PYTHONPATH 变量并编辑环境变量，但似乎没有任何效果。

我的代码如下。如果更容易，我也可以通过电子邮件发送我的设置的 zip：

到目前为止，这似乎可行：我将 PYTHONHOME 和 PYTHONPATH 设置为 Maya 在默认设置中想要的目录。确保这些目录在列表中的第一位，否则当前的虚拟环境仍将覆盖 Maya 的 python。

#.....

# Python path envs
_python_path_list = [
    'C:\\Program Files\\Autodesk\\Maya2020\\Python\\Lib\\site-packages',
    'C:\\Program Files\\Autodesk\\Maya2020\\Python\\DLLs',
    os.path.join(self.root_path, 'scripts').replace('\\', '/'),
    os.path.join(self.root_path, 'sourcessss', 'main_app')
]

# PYTHONPATH exe vs ide
if getattr(sys, 'frozen', False):

    _envs['PYTHONPATH'] = os.pathsep.join(_python_path_list)
    _envs['PYTHONHOME'] = 'C:\\Program Files\\Autodesk\\Maya2020\\bin'
