Question

在Windows 7上尝试使用cx_Freeze pyzmq依赖的Python 3.4应用程序时，我在运行可执行文件时遇到异常，我无法理解。为简洁而编辑的错误回溯看起来像这样：

ImportError: DLL load failed: The specified module could not be found.

该错误的具体原因是什么，即缺少哪个模块（我假设的DLL）？

Answer 1

提示位于以下追溯条目中：

File "C:\Python34\lib\site-packages\zmq\backend\cython\__init__.py", line 6, in <module>
  from . import (constants, error, message, context,

它没有给出错误的直接答案，但确实指向模块zmq.backend.cython.constants等是问题，即它们缺少DLL依赖性。在使用DependencyWalker进行检查后，发现'C：\ Python34 \ lib \ site-packages \ zmq \ libzmq.pyd'是有问题的DLL依赖项。如果该文件包含在冻结的应用程序中，则可以正常工作。

这个cx_Freeze错误是什么意思？
