无效dsn：无效的连接选项“ postgis_extension”

Question

在localhost上，一切正常。但是我在使用https://rossdjangoapp.herokuapp.com/时遇到问题。

我试图遵循本教程https://medium.com/the-geospatials/deploy-geodjango-application-to-heroku-in-2019-part-3-41ca4535f377。

我收到以下错误消息。

remote: -----> App not compatible with buildpack: https://github.com/peterkeen/heroku-buildpack-


remote:  !     The GDAL, GEOS and PROJ binaries and BUILD_WITH_GEO_LIBRARIES functonality are now deprecated.
remote:  !     An alternative buildpack to enable GDAL, GEOS and PROJ use is available here - https://github.com/heroku/heroku-geo-buildpack


remote:        ### WARNING: THIS BUILDPACK HAS BEEN DEPRECATED
remote:        Please check https://git.io/fj5QW

这些是我现在拥有的构建包。

我想向我的网站添加地图功能。

django_heroku.settings(locals())

现在正在工作

我看着Adems的答案（Running PostGIS with Django on Heroku）。并且还必须转到https://data.heroku.com/，单击“设置”，然后查看数据库凭据。

Answer 1

[删除settings.py文件中的所有外部导入，例如heroku导入并删除django_heroku.settings（locals（）），但仅保留AWS设置，然后再次运行
