pythonxy和spyder在ConfigParser.py中无法启动类型错误

Question

一直在通过PythonXY使用Spyder，今天它停止了工作。我似乎能够启动PythonXY程序文件夹中的其他功能(例如，Mayavi、Ipython控制台等)，但PythonXY或Spyder都不会正常启动。当我从命令行启动它们时，我会得到以下错误跟踪。关于如何解决这个问题(已经尝试过卸载和重新安装pythonxy/python)，有什么建议吗？

Traceback (most recent call last):
  File "C:\Python27\Scripts\xyhome.pyw", line 20, in <module>
    from xy import xyhome
  File "C:\Python27\lib\site-packages\xy\xyhome.pyw", line 60, in <module>
    from xy.config import (CONF, STARTUP_PATH, LOG_PATH, PLUGINS, XY_VERSION,
  File "C:\Python27\lib\site-packages\xy\config.py", line 40, in <module>
    CONF = UserConfig('xy', defaults=DEFAULTS, version=__version__, subfolder='.
xy')
  File "C:\Python27\lib\site-packages\xy\userconfig.py", line 110, in __init__
    if version != self.get_version(version):
  File "C:\Python27\lib\site-packages\xy\userconfig.py", line 130, in get_versio
n
    return self.get(self.DEFAULT_SECTION_NAME, 'version', version)
  File "C:\Python27\lib\site-packages\xy\userconfig.py", line 266, in get
    self.set(section, option, default)
  File "C:\Python27\lib\site-packages\xy\userconfig.py", line 332, in set
    self.__save()
  File "C:\Python27\lib\site-packages\xy\userconfig.py", line 167, in __save
    self.write(conf_file)
  File "C:\Python27\lib\ConfigParser.py", line 407, in write
    fp.write("[%s]\n" % section)
TypeError: must be unicode, not str
>>>

当我从上一次conf_file调用中打印出userconfig.py时，参数看起来确实是unicode：

<_io.TextIOWrapper name=u'C:\\Users\\rclement\\.xy\\.xy.ini' encoding='utf-8'>

我能够通过删除C:\Python27 27目录和非pythonxy安装包留下的相关子目录来重新安装。没有进行注册表更改，Windows环境路径设置与我设置的设置相同。我仍然不知道问题的原因。

我对这个错误做了快速修复。

    for section in self._sections:
        fp.write("[%s]\n" % unicode(section)) #forced conversion to unicode
        for (key, value) in self._sections[section].items():
            if key == "__name__":
                continue
            if (value is not None) or (self._optcre == self.OPTCRE):
                key = " = ".join((key, str(value).replace('\n', '\n\t')))
            fp.write("%s\n" % (unicode(key))) #forced conversion to unicode
        fp.write(u"\n") #forced conversion to unicode

这个快速解决方案对我有效。但不知道是什么导致了这个问题。:-(
