我正在尝试遵循Django教程（https://docs.djangoproject.com/en/1.6/intro/tutorial01/）
我试图跑：
python manage.py syncdb
导致错误：

我有同样的问题，但我解决了不同的问题。如果将来有其他人遇到此问题并且上述解决方案对您不起作用，请尝试从此处编辑mimetypes.py：
with _winreg.OpenKey(_winreg.HKEY_CLASSES_ROOT, '') as hkcr:
for subkeyname in enum_types(hkcr):
try:
with _winreg.OpenKey(hkcr, subkeyname) as subkey:
# Only check file extensions
if not subkeyname.startswith("."):
continue
到此：
with _winreg.OpenKey(_winreg.HKEY_CLASSES_ROOT, '') as hkcr:
for subkeyname in enum_types(hkcr):
try:
if '\0' in subkeyname: #ADD THIS LINE
print("Skipping bad key: %s" % subkeyname) #ADD THIS LINE
continue #ADD THIS LINE
with _winreg.OpenKey(hkcr, subkeyname) as subkey:
# Only check file extensions
if not subkeyname.startswith("."):
continue
就像我说的那样，这个答案只适用于遇到此问题的其他人，并没有成功实施任何其他答案。

问题在于我的Windows安装本身。有一些密钥具有无效字符，mimetype.py正在循环查找文件关联。
为mimetype.py（+/- ln.255）添加了变通方法：
**ln 252**
import re
**ln. 255**
pattern = re.compile('[\W{}\[\]_]+')
subkeyname = pattern.sub('',subkeyname)
实际上，它会在将其作为注册表项名称进行评估之前对子角色名称中的所有无效字符进行条带化。
不是最好的，但它有效。并且可能特定于此安装。
