嵌入式Python解释器无法导入c模块

问题描述：

我在MinGW-w64项目（https://sourceforge.net/p/mingw-w64/discussion/723798/thread/4a8a9ed5/?limit=25）的gdborig.exe中有嵌入式python解释器问题。嵌入式Python解释器无法导入c模块

导入模块itertools和其他几个失败。但随着分布式独立Python解释器相应的进口做工精细：

>>> import sys 
>>> print sys.version 
2.7.9 (default, Jul 11 2016, 16:32:13) 
[GCC 6.1.0] 
>>> print sys.executable 
C:/AUEMARK/Programme/MinGW64/mingw64/opt/bin/python.exe 
>>> import itertools 
>>> itertools 
<module 'itertools' from 'C:\AUEMARK\Programme\MinGW64\mingw64\opt\libpython2.7\lib-dynload/itertools.pyd'>

随着嵌入式Python解释器：

(gdb) python import sys 
(gdb) python print sys.version 
2.7.9 (default, Jul 11 2016, 16:32:13) 
[GCC 6.1.0] 
(gdb) python print sys.executable 
C:/AUEMARK/Programme/MinGW64/mingw64/opt/bin/python.exe 
(gdb) python import itertools 
Traceback (most recent call last): 
    File "<string>", line 1, in <module> 
ImportError: No module named itertools 
Error while executing Python code.

可以：

进口SYS
进口OS

不能：

进口itertools
进口藏品
...

对集合的进口错误消息

(gdb) python import collections 
Traceback (most recent call last): 
    File "<string>", line 1, in <module> 
    File "C:\AUEMARK\Programme\MinW64\mingw64\opt\lib\python2.7/collections.py", line 8, in <module> 
    from _collections import deque, defaultdict 
Importerror: no module named _collections 
Error while executing Python code.

所以看起来像嵌入式解释不能在C中导入模块。Python模块被导入，并且C模块的Python部分也可以被导入由嵌入式解释器访问。

感谢您的任何提示，我该如何解决这个问题。

我觉得这个问题存在，因为找不到itertools.pyd文件。我必须设置环境变量：

PYTHONPATH=C:\msys64\mingw64\lib\python2.7;C:\msys64\mingw64\lib\python2.7\lib-dynload;

你的情况，请确保您设置：

PYTHONPATH=C:/AUEMARK/Programme/MinGW64/mingw64/opt/lib/python2.7;C:\AUEMARK\Programme\MinW64\mingw64\lib\python2.7\lib-dynload

我PYTHONHOME变量指向Python解释：

PYTHONHOME=C:\msys64\mingw64\bin\pyhon.exe

我建立了自己的gdb在msys2下工作：

没有设置正确的环境变量我有同样的麻烦。
