使用ctypes（python）加载带有括号的路径中的dll错误 [英] Error loading dll in path with parenthesis using ctypes (python)

问题描述

我正在尝试访问位于64位处理器PC中的c：/ Program Files（x86）文件夹中的dll。

I am trying to access a dll located in the "c:/Program Files (x86)" folder in a 64-bits processor PC.

如果我使用os.path.exists来检查DLL是否存在，我收到一个确定的答案：

If I use os.path.exists to check if the dll exists, I receive an afirmative answer:

>>> print os.path.exists('c:/Program Files (x86)/Some Folder/SomeDll.dll')
True

但是当我尝试使用ctypes加载dll时，我收到以下错误：

But when I try to load the dll using ctypes, I get the following error:

>>> from ctypes import WinDLL
>>> some_dll = WinDLL('c:/Program Files (x86)/Some Folder/SomeDLL.dll')
Traceback (most recent call last):
  File "<console>", line 1, in <module>
  File "C:\Python26\lib\ctypes\__init__.py", line 353, in __init__
    self._handle = _dlopen(self._name, mode)
WindowsError: [Error 126] The specified module could not be found

在32位PC中，dll位于在c：/ Program Files文件夹中，我可以打开它没有问题。我认为问题可能是文件夹名称中存在括号。由于返回的异常是WindowsError，它似乎是负责加载库的操作系统函数的缺陷。

In 32-bit PCs the dll is located in the "c:/Program Files" folder and I can open it without problems. I think that perhaps the problem is the presence of parenthesis in the folder name. As the returned exception was a WindowsError, it seems that it is a flaw in the operating system function responsible of loading libraries.

所以问题是：如何加载一个dll位于c：/ Program Files（x86）文件夹中？我不能将dll复制到另一个目的地，它必须位于原始路径...

So, the question is: how do I load a dll located in the "c:/Program Files (x86)" folder? I can't copy the dll to another destination, it must be located in the original path...

谢谢！

推荐答案

您是否尝试过C：/ Progra〜1 / SomeFolder / SomeDll？

Have you tried "C:/Progra~1/SomeFolder/SomeDll" ?

另一个建议：

 os.chdir(r"C:\Program Files(x86)\SomeFolder")
 the_dll = WinDLL("SomeDLL.dll")
