python - Django：导入@wraps时的AppRegistryNotReady

Question

使用时收到以下错误wraps。

附加装饰器，我正在使用 wraps 函数。

from functools import wraps

    @wraps(func)
    def wrapper(*args, **kwargs):
        if settings.MIXPANEL_ID:
            func(*args, **kwargs)
        else:
            print("Check for settings.MIXPANEL_ID failed.")
    return wrapper
