启动任何 python 程序时出现 os.path.exist(path) 错误

Question

我不明白为什么我在以下几行中收到递归深度错误

source = zipfile.ZipFile( "E:\\Zip Files\\80348.zip' , 'r' )
source.extractall()

文件存在并且我能够打开它。我得到的回溯是，

Traceback (most recent call last):
File "<interactive input>", line 1, in <module>
File "C:\Python26\lib\zipfile.py", line 940, in extractall
 self.extract(zipinfo, path, pwd)
File "C:\Python26\lib\zipfile.py", line 928, in extract
 return self._extract_member(member, path, pwd)
File "C:\Python26\lib\zipfile.py", line 961, in _extract_member
 if upperdirs and not os.path.exists(upperdirs):
File "C:\Python26\lib\genericpath.py", line 18, in exists
 st = os.path.exists(path)
File "C:\Python26\lib\genericpath.py", line 18, in exists
 st = os.path.exists(path)

你能告诉我这里出了什么问题吗......

编辑：-

嘿，我刚刚发现这不是来自zipfile的错误......我运行任何其他 python 程序，我都会得到相同的错误......

当我在命令行上键入 python 时，我收到错误

Exception RuntimeError: 'maximum recursion Derecessed in __subclasscheck__' 在<类型'异常.RuntimeError'>中被忽略 异常运行时错误：“调用 Python 时超出最大递归深度” 中的对象'被忽略 “导入站点”失败；使用 -v 进行回溯

我不认为该错误与 zipfile 有关，因为我也看到了这个链接.... 导入站点错误

我尝试使用 -v 并得到以下回溯

我应该做什么...有谁面临同样的问题？
