[python]pyzmq 的 pyinstaller 打包失敗

這個也算是一拳解決，所以要先來描述一下問題。

環境

環境是 windows，python2.7，用 pip install zerorpc。
到了要打包的時候，pyinstaller 會吐出 warning：

4736 INFO: Looking for dynamic libraries

真的執行的話，會出現：

File "site-packages\zmq\backend\cython\__init__.py", line 6, in <module>
File "c:\users\cyrus\appdata\local\temp\pip-build-ont0l7\pyinstaller\PyInstall
er\loader\pyimod03_importers.py", line 546, in load_module
ImportError: DLL load failed: 找不到指定的模組。
Failed to execute script api

一拳

C:\Python27\Lib\site-packages\zmq\libzmq.pyd 要複製一份到 C:\Python27\Lib\site-packages\zmq\backend\cython\

搞定
