我无法从捆绑的.exe程序(Python 37)启动Maya 2020(Python 27)。我已经使用pyinstaller捆绑了exe。
如果从IDE启动我的工具,它将启动Maya罚款。当我从.exe启动我的工具时,模块中的多个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. #
我已经尝试过建议in this post,但不确定自己在做什么错。
我的代码在下面。如果更简单,我也可以通过电子邮件发送设置的压缩文件:

似乎我从未将要设置为PYTHONPATH
的列表转换为字符串,因此这些值从未带入子进程(毕竟环境变量必须为字符串)。我没有收到任何错误,所以它越过了我。
这就是为什么我试图在该代码段中编辑和设置PATH
env var。
所以launch_maya.py
中的这个:
# PYTHONPATH exe vs ide
if getattr(sys, 'frozen', False):
# There is no PYTHONPATH to add so, so I create it here (Do I need this? Is there a diff way?)
_envs['PYTHONPATH'] = os.pathsep + os.pathsep.join(_python_path_list)
# Insert mayapy.exe into front of PATH
sys_path = sys.path
maya_py_path = os.path.join('C:', os.sep, 'Program Files', 'Autodesk', 'Maya2020', 'bin', 'mayapy.exe')
sys.path.insert(0, maya_py_path)
_envs['PATH'] = str(sys_path)
需要更改为此:
if getattr(sys, 'frozen', False):
# Get existing pypath
sys_path_ = _envs['PYTHONPATH']
# Combine path list
maya_py_path_list = os.pathsep.join(_python_path_list)
# Insert path_list before any existing paths
sys_path = maya_py_path_list + os.pathsep + sys_path_
# Set PYTHONPATH
_envs['PYTHONPATH'] = sys_path
