正在设置全新的虚拟环境和 postgres 数据库，甚至无法进行迁移。该系统 运行 在其他 2 台电脑
上运行良好
python3.5 已安装
已创建虚拟环境
应用"requirements.txt"安装成功
manage.py 使用创建的配置识别 postgres 服务器

py 和 postgres 都在 PATH 上
虚拟环境已激活
在安装 psql
时为 "postgres" 创建的超级用户检查了 pgAdmin III
然后开始问题
已经强制删除数据库
在迁移中搜索了 "api_role" 相关问题
每一个答案我都会关注。
每个人都说 makemigrations。当您无法进行初始 makemigrations 时怎么办
删除所有迁移和新鲜"makemigrations"
卸载并安装
当问题仍然存在时格式化电脑
我预计至少会进行初始 makemigrations
注意到其他机器可能在数据库中有这种缺失的关系，但在迁移中没有。

有时，当您在表单本身上查询数据库时，表单在迁移时会出现问题。
如果你想用数据库中的任何东西进行 pupulate，请在 init
