几天前完成yum升级后,我的Django项目出现以下错误

升级前该项目正常运行,并尝试修复我安装了gdal 3.0.2的错误,但它不起作用

我不知道您是否需要有关该项目或虚拟机的更多信息,可以询问我,我很乐意为您提供任何信息

任何想法?

对于我来说,yum具有多个已启用的pgdg存储库,而gdal lib是从与Postgis不同的pg版本安装的。在将启用的pgdg存储库减少到一个(感兴趣的版本)并重新安装(或更好地擦除并安装)受影响的软件包后,我又可以将pg与Postgis一起使用。

如何禁用存储库,请参阅How to enable or disable repositories in CentOS。在我的情况下,相关文件是/ etc / yum.repos.d / pgdg-redhat-all.repo

在升级之前已经存在混合存储库的情况,并且Postgis正常工作没有麻烦

<< yum更新后>>混合存储库的情况有所扩展,postgis造成了麻烦。 (grep搜索pgdg以检测所有受影响的软件包)[test@mytest ~]$ yum list installed | grep -i pgdg CGAL.x86_64 4.7-1.rhel7.1 @pgdg11 SFCGAL.x86_64 1.3.1-2.rhel7 @pgdg12 SFCGAL-libs.x86_64 1.3.1-2.rhel7 @pgdg12 gdal-libs.x86_64 1.11.4-12.rhel7 @pgdg96 gdal30-libs.x86_64 3.0.1-4.rhel7 @pgdg10 geos37.x86_64 3.7.2-2.rhel7 @pgdg10 libgeotiff.x86_64 1.4.0-1.rhel7.1 @pgdg11 libgeotiff15.x86_64 1.5.1-2.rhel7 @pgdg12 ogdi.x86_64 3.2.0-4.rhel7.1 @pgdg11 ogdi41.x86_64 4.1.0-2.rhel7 @pgdg10 pgdg-redhat-repo.noarch 42.0-5 @pgdg10 postgis24_96.x86_64 2.4.8-5.rhel7 @pgdg96 ... proj62.x86_64 6.2.0-1.rhel7 @pgdg10 [test@mytest ~]$ psql ... test=# CREATE EXTENSION postgis; ERROR: could not load library "/usr/pgsql-9.6/lib/rtpostgis-2.4.so": /usr/gdal30/lib/libgdal.so.26: undefined symbol: GEOSMakeValid_r test=#

我试图仅启用一个pgpdg存储库来重新安装Postgis。这不是重新安装相关的geos,gdal,proj软件包。因此,我删除了所有受影响的软件包并重新安装。 

[test@mytest ~]$ sudo yum erase CGAL geos37 proj62 proj49 ogdi41 [test@mytest ~]$ sudo yum install postgis24_96 [test@mytest ~]$ yum list installed | grep -i pgdg CGAL.x86_64 4.7-1.rhel7 @pgdg96 SFCGAL.x86_64 1.3.1-1.rhel7 @pgdg96 SFCGAL-libs.x86_64 1.3.1-1.rhel7 @pgdg96 gdal30-libs.x86_64 3.0.4-2.rhel7 @pgdg96 geos38.x86_64 3.8.0-1.rhel7 @pgdg96 ... postgis24_96.x86_64 2.4.8-8.rhel7 @pgdg96

这是一项艰巨的系统更改,请确保具有备份(例如VM快照)。还要检查是否依赖的其他安装(例如python正常安装)仍然可以与更改的库一起使用或需要重新安装。
