Django无法在Ubuntu上加载SpatiaLite库扩展mod_spatialite

标签: django python-3.x sqlite ubuntu-16.04 spatialite

我正在尝试使用spatialite运行sqlite3,但是当我运行

 $ python manage.py makemigrations

我收到错误消息:

  

django.core.exceptions.ImproperlyConfigured:无法加载   SpatiaLite库扩展“ mod_spatialite”是因为:   mod_spatialite.so:无法打开共享对象文件:无此文件或   目录

我正在使用

  • Ubuntu 16.04 Xenial
  • Django 1.11
  • Python 3.5.2

并已安装软件包:

  • spatialite-bin
  • spatialite-gui
  • spatialite-gui-dbg
  • python-pyspatialite

我也尝试添加SPATIALITE_LIBRARY_PATH = 'mod_spatialite',但仍然无法正常工作。

我的完整追溯:

我通过重新安装每个软件包并添加我可以使用突触软件包管理器找到的每个spacespaceite软件包来解决。我已安装的软件包列表:

  • librasterlite2-1
  • libspatialite-dbg
  • libspatialite7
  • libsqlite3-mod-rasterlite2
  • libsqlite3-mod-spatialite
  • spatialite-bin
  • spatialite-gui
  • spatialite-gui-dbg
  • python-pyspatialite

您只需要通过运行以下命令来安装libsqlite3-mod-spatialite:

sudo apt-get install libsqlite3-mod-spatialite
