我试图在Heroku上使用PostGIS设置GeoDjango站点。我一直试图谷歌这个属性错误我得到但我无法找到信息或解决方案。尝试使用heroku run python manage.py migrate进行迁移或迁移数据库时，会返回此错误。
AttributeError: 'DatabaseOperations' object has no attribute 'select'
我在当地没有遇到任何问题。我已按照Heroku上的说明操作并创建了数据库扩展。 https://devcenter.heroku.com/articles/heroku-postgres-extensions-postgis-full-text-search#postgis和https://devcenter.heroku.com/articles/postgis
my-site::DATABASE=> SELECT postgis_version();
postgis_version
---------------------------------------
2.3 USE_GEOS=1 USE_PROJ=1 USE_STATS=1
(1 row)
任何人都可以对可能出现的问题有所了解，帮助我排除故障。我没有在Heroku上正确配置数据库吗？
谢谢
