Django 迁移错误

真正的新手

将 Psycopg2==2.7.4 导入我的服务器后，我无法再正常运行我的服务器。添加新字段后，每当我尝试在 makemigrations(python manage.py migrate) 之后进行迁移时，都会在我的终端中发生这种情况：

 Apply all migrations: admin, auth, buddysapp, contenttypes, oauth2_provider, sessions, social_django
Running migrations:

任何想法，让我知道。

更新：迁移文件 0038

rom __future__ import unicode_literals

import buddysapp.models
import django.contrib.postgres.fields.jsonb
from django.db import migrations, models


class Migration(migrations.Migration):

    dependencies = [

    ]

    operations = [
        migrations.AddField(
            model_name='dispensary',
            name='businessHours',
            field=django.contrib.postgres.fields.jsonb.JSONField(blank=True, default=buddysapp.models.business_hours_default, null=True),

        ),

您不能将JSONFieldfromdjango.contrib.postgres与 Sqlite3 数据库一起使用。

您需要设置 PostgreSQL 数据库并更新您的DATABASES设置，或者在您的模型中使用不同的字段。
