若按照之前的步骤build时还是会出错，错误信息如下：
fatal error LNK1104: cannot open file 'python27_d.lib'
原因：我们使用的头文件 <Python.h>调用了"pyconfig.h"
#include "pyconfig.h"
而在"pyconfig.h"中有用到"python27_d.lib"
/* For an MSVC DLL, we can nominate the .lib files used by extensions */ #ifdef MS_COREDLL # ifndef Py_BUILD_CORE /* not building the core - must be an ext */ # if defined(_MSC_VER) /* So MSVC users need not specify the .lib file in their Makefile (other compilers are generally taken care of by distutils.) */ # ifdef _DEBUG # pragma comment(lib,"python27_d.lib") # else # pragma comment(lib,"python27.lib") # endif /* _DEBUG */ # endif /* _MSC_VER */ # endif /* Py_BUILD_CORE */ #endif /* MS_COREDLL */
比较简单的解决办法是：
请将C:/Python27/libs下的python27.lib复制一份改名为python27_d.lib
