ctypes.cdll.loadlibrary忽略ld_library_path env变量

Question

我有一个C ++动态库，该库使用另一组动态库（VLC LIB）， 当我尝试在Python中加载库（libmylib.dylib）时：

import ctypes
lib = ctypes.cdll.LoadLibrary('./libmylib.dylib')

我会得到一个错误：

  File "test.py", line 5, in <module>
    lib = ctypes.cdll.LoadLibrary('./libmylib.dylib')
  File "/Library/Developer/CommandLineTools/Library/Frameworks/Python3.framework/Versions/3.8/lib/python3.8/ctypes/__init__.py", line 443, in LoadLibrary
    return self._dlltype(name)
  File "/Library/Developer/CommandLineTools/Library/Frameworks/Python3.framework/Versions/3.8/lib/python3.8/ctypes/__init__.py", line 365, in __init__
    self._handle = _dlopen(self._name, mode)
OSError: dlopen(./libmylib.dylib, 0x0006): Library not loaded: @rpath/libvlc.dylib
  Referenced from: ./libmylib.dylib
  Reason: tried: '/usr/local/lib/libvlc.dylib' (no such file), '/usr/lib/libvlc.dylib' (no such file)

为了使其正常工作，我必须明确加载VLC依赖关系库：

import ctypes
ctypes.cdll.LoadLibrary('/Applications/VLC.app/Contents/MacOS/lib/libvlccore.dylib')
ctypes.cdll.LoadLibrary('/Applications/VLC.app/Contents/MacOS/lib/libvlc.dylib')
lib = ctypes.cdll.LoadLibrary('./libmylib.dylib')

我尝试设置ld_library_path ld_library_path < /code> and library_path没有运气的环境变量：

VLC_PLUGIN_PATH=/Applications/VLC.app/Contents/MacOS/plugins
LD_LIBRARY_PATH=/Applications/VLC.app/Contents/MacOS/lib/
RUN_LD_PATH=/Applications/VLC.app/Contents/MacOS/lib/
LIBRARY_PATH=/Applications/VLC.app/Contents/MacOS/lib/

是否可以通过位置（目录）找到VLC动态库的位置（目录），并避免使用ctypes.cdll明确加载它们。 LoadLibrary？ 如何？

注意：我在此实验中使用的操作系统是MacOS Monterey 12.4，而我使用的Python版本为：3.8.9

更新

outtup of：

DYLD_LIBRARY_PATH=/Applications/VLC.app/Contents/MacOS/lib python3 -c 'import os; print(os.environ.get("DYLD_LIBRARY_PATH"))'
None

note none，所有dyld_*库是完全被忽略，似乎与此问题。
