求助，pyfa运行报错~~~~

夜空下的猫

如题

我台式机上运行就ok，但是在笔记本上运行就弹出窗口：
errors occurred
see the logfile ‘E:\Games\EVE_tools\2014\pyfa-cn\pyfa.exe.log' for details'

找到这个log文件后，打开，里面有以下内容：

Traceback (most recent call last):
  File "pyfa.py", line 70, in <module>
    usage = "usage: %prog [--root]"
  File "config.py", line 58, in defPaths
    sys.stderr = open(os.path.join(savePath, "error_log.txt"), "w")
WindowsError: [Error 3] : u'%HOMEDRIVE%%HOMEPATH%\\.pyfa'
Traceback (most recent call last):
  File "pyfa.py", line 70, in <module>
  File "config.py", line 58, in defPaths
WindowsError: [Error 3] : u'%HOMEDRIVE%%HOMEPATH%\\.pyfa'


有人能看懂为啥报错吗？是缺什么必要的运行库？
