Heroku:django.core.exceptions.ImproperlyConfigured:找不到 GDAL

Question

我正在尝试在 heroku 上运行 geodjango 应用程序，我添加了一个构建包以使 gdal 可用

https://github.com/cyberdelia/heroku-geo-buildpack.git .在推送期间，它说 gdal 和其他 geotools 已成功安装

当我请求页面时，它说应用程序错误。

Is GDAL installed? If it is, try setting GDAL_LIBRARY_PATH in your settings.>

我应该在设置中指定一些路径还是我使用的是不兼容的版本？ (我正在使用 Django==2.0.2)

Answer 1

来自 Heroku's docs ，将以下内容添加到您的 settings.py 中:

import dj_database_url
DATABASES['default'] =  dj_database_url.config()
DATABASES['default']['ENGINE'] = 'django.contrib.gis.db.backends.postgis'

GDAL_LIBRARY_PATH = os.getenv('GDAL_LIBRARY_PATH')
GEOS_LIBRARY_PATH = os.getenv('GEOS_LIBRARY_PATH')
