“苹果的Python”：OSERROR：执行dlopen（libps2000a.dylib，6）：没有找到图片，但不是在IPython中

Question

在MacOS，我已经设置DYLD_LIBRARY_PATH这样：

export DYLD_LIBRARY_PATH=/Applications/PicoScope6.app/Contents/Resources/lib 

如果我跑这两条线IPython的，它的工作原理：

from ctypes import cdll 
cdll.LoadLibrary("libps2000a.dylib") 

，但我在标准Python解释器运行它们，我得到：

$ /usr/bin/python 
Python 2.7.10 (default, Feb 7 2017, 00:08:15) 
[GCC 4.2.1 Compatible Apple LLVM 8.0.0 (clang-800.0.34)] on darwin 
Type "help", "copyright", "credits" or "license" for more information. 
>>> from ctypes import cdll 
>>> cdll.LoadLibrary("libps2000a.dylib") 
Traceback (most recent call last): 
    File "<stdin>", line 1, in <module> 
    File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/ctypes/__init__.py", line 443, in LoadLibrary 
    return self._dlltype(name) 
    File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/ctypes/__init__.py", line 365, in __init__ 
    self._handle = _dlopen(self._name, mode) 
OSError: dlopen(libps2000a.dylib, 6): image not found 

EDIT1：我THI NK它有什么用苹果提供的，因为与/usr/local/bin/python2（由brew工具提供），它的工作原理的Python：

$ /usr/local/bin/python2 
Python 2.7.13 (default, Jul 18 2017, 09:17:00) 
[GCC 4.2.1 Compatible Apple LLVM 8.1.0 (clang-802.0.42)] on darwin 
Type "help", "copyright", "credits" or "license" for more information. 
>>> from ctypes import cdll 
>>> cdll.LoadLibrary("libps2000a.dylib") 
<CDLL 'libps2000a.dylib', handle 7f8838d01f80 at 10b438f50> 

EDIT2：我有同样的PB。与DYLD_LIBRARY_PATH变量作为与LD_LIBRARY_PATH可变

我能做些什么来“告诉”“苹果的Python”到“看” DYLD_LIBRARY_PATH？

Answer 1

MacOS X上它是DYLD_LIBRARY_PATH不LD_LIBRARY_PATH。

对环境变量可以设置影响动态连接器的详细信息请参见dyld手册页。
