Pyinstaller Python ImportError: No module named publisher

问题

在python应用程序中使用了pubsub，使用工具调试的运行一切正常，但是使用pyinstaller 将程序打包成exe文件后，出现如下错误。

Traceback (most recent call last): 
File "upload_test_run_dynamic_clean.py", line 21, in <module> 
from wx.lib.pubsub import pub 
File "c:\python27\Lib\site-packages\PyInstaller\loader\pyimod03_importers.py", line 389, in load_module 
exec(bytecode, module.__dict__)
 File "site-packages\wx-3.0-msw\wx\lib\pubsub\pub.py", line 35, in <module> File "c:\python27\Lib\site-packages\PyInstaller\loader\pyimod03_importers.py", line 389, in load_module 
ImportError: No module named publisher

然后在查看pyinstaller工具将程序打包的过程中出现的日志文件发现有一个地方出现错误日志

说没有找到pubsub相关的库文件，但是到库安装的目录下看，wx.lib.pubsub.core目录下确实没有这几个文件，这几个文件都在wx.lib.pubsub.core.kwargs/wx.lib.pubsub.core.arg1目录下。

当wxPython >= 2.8.11.0, 使用kwargs中目录的文件
其他版本使用arg1中的文件

解决方式

将kwargs中相关的文件拷贝到core目录下面，然后使用pyinstaller重新生成exe重新
