AttributeError: function 'initGEOS_r' not found

我在尝试运行我的服务器时收到AttributeError: function 'initGEOS_r' not found 错误。 我正在尝试编写一个基本的 Geo Django 程序 我还安装了 Postgres 和 GEOS

我还在我的 settings.py 文件中包含了 GEOS 和 GDAL 路径。

我已经尝试了所有可能的方法来解决此错误，但无法解决。 有人可以帮帮我吗!

Answer 1

我遇到了同样的问题，这对我有用:

1. 在 settings.py 上写:

GDAL_LIBRARY_PATH = r'C:\OSGeo4W64\bin\gdal204'
GEOS_LIBRARY_PATH = r'C:\OSGeo4W64\bin\geos_c.dll'
PROJ_LIBRARY_PATH = r'C:\OSGeo4W64\share\proj'

1. 在 settings.py 上的 INSTALLED_APPS 代码:

'django.contrib.gis',

1. 将 postgis 添加到后端

DATABASES = {
    'default': {
        'ENGINE': 'django.contrib.gis.db.backends.postgis',
        'NAME': 'xxx',
        'USER': 'yyy',
        'PASSWORD': 'xxx',
        'HOST': '',
        'PORT': '1234',
    }
}

记住你的模型应该继承自 从 django.contrib.gis.db 导入模型
