Django无法在Ubuntu上加载SpatiaLite库扩展mod_spatialite

Posted 2021-05-04

我正在尝试使用spatialite运行sqlite3，但是当我运行时

 $ python manage.py makemigrations

我得到错误：

django.core.exceptions.ImproperlyConfigured：无法加载SpatiaLite库扩展“mod_spatialite”，因为：mod_spatialite.so：无法打开共享对象文件：没有这样的文件或目录

我正在使用

• Ubuntu 16.04太棒了
• Django 1.11
• Python 3.5.2

并安装了包：

• spatialite斌
• spatialite贵
• spatialite贵，DBG
• 蟒蛇，pyspatialite

我也试过添加qazxsw poi，但它仍然没有用。

我的完整追溯：

SPATIALITE_LIBRARY_PATH = 'mod_spatialite'

答案

我通过改变修复了这个问题

During handling of the above exception, another exception occurred:

至

SPATIALITE_LIBRARY_PATH = 'mod_spatialite'

按照这个SPATIALITE_LIBRARY_PATH = 'mod_spatialite.so' 。

另一答案

我解决了重新安装每个包并添加我使用synaptic包管理器找到的每个空间包。我安装的软件包列表：

• librasterlite2-1
• libspatialite-DBG
• libspatialite7
• libsqlite3-MOD-rasterlite2
• libsqlite3-MOD-spatialite
• spatialite斌
• spatialite贵
• spatialite贵，DBG
• 蟒蛇，pyspatialite

另一答案

您只需运行以下命令即可安装libsqlite3-mod-spatialite：
