百度了好久都没有。只能自己找。

最后发现是在seeting里面进行app注册时出错，

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'users.apps.UsersConfig',
    'DjangoUeditor',
    'goods.apps.GoodsConfig',
    #这是错误的，由于是点回车，太快，导致的
    #trade.apps.AppConfig
    'trade.apps.TradeConfig',
    'user_operation.apps.UserOperationConfig',
改回来就OK了。
                                    关于AttributeError: type object ‘XXXXXX’ has no attribute 'name’的报错的原因，先运行运行一段代码
class Person(object):
    def __init__(self,name):
        self.name=name
    def play(self):
        print('工作')
if __name__ == '__main__':
    p=Person('KB')
    p.play
                                    这两天在学习python的时候，会搞一些测试代码，有时候控制台就会有“AttributeError: 'function' object has no attribute 'name'”的报错，编译器也没报错
                                    0. 概述：
settings.py文件中的INSTALLED_APPS中添加自定义子应用时，需要将子应用所在目录加入导报路径sys.path（如果子应用本身就在项目根路径下就不需要）。要么就要设置子应用的配置类的name值带上导包路径。
1. 相关报错：
django.core.exceptions.ImproperlyConfigured: Cannot import ‘users’. Check that ‘meiduo_project.apps.users.apps.UsersConfig.nam
                                    在项目(blogsite)注册应用(blog)时提示错误信息：[blog.apps.AppConfig]must supply a name attribute
错误写法：
INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',

很明显是if type(secondDict[key])._name_  == ‘dict’:这一句有问题，在python3中并没有type(secondDict[key])._n
