我试图按照Django教程（ https://docs.djangoproject.com/en/1.6/intro/tutorial01/ ）
我试图运行：
python manage.py syncdb 这导致了错误：

我有同样的问题，但我解决它不同。 如果以后有其他人有这个问题，上面的解决方案不适合你，请尝试从这个编辑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
对此：
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，这个答案只是针对任何其他人遇到这个问题，没有成功实施任何其他答案。
问题是我的Windows安装本身。 有一些密钥有无效的字符mimetype.py正在循环查找文件关联。
将解决方法添加到mimetype.py（+/- ln。255）：
**ln 252** import re **ln. 255** pattern = re.compile('[\W{}\[\]_]+') subkeyname = pattern.sub('',subkeyname)
实际上，在将子键名称评估为注册表键名称之前，它会从子键名称中除去所有无效的字符。
不是最好的，但它的工作原理。 可能是特定于此安装。
