安装索引失败(Geodjango相关)

Question

我在用geoDjango.我已经从源代码安装下面的软件包Gdal,proj1.4,geos3.3.5和Postgis2.0.1.我是ubuntu用户.当我跑完syncdb后,我得到以下错误.我错过了什么吗？谢谢

Answer 1

也许我有点迟了但我解决了这个问题(Django 1.4.x,Postgis 2.0.1和PostgreSQL 9.2)在template_postgis数据库中创建一个运算符类,如下所示:

CREATE OPERATOR CLASS gist_geometry_ops
FOR TYPE geometry USING GIST AS
STORAGE box2df,
OPERATOR        1        <<  ,
OPERATOR        2        &<  ,
OPERATOR        3        &&  ,
OPERATOR        4        &>  ,
OPERATOR        5        >>  ,
OPERATOR        6        ~=  ,
OPERATOR        7        ~   ,
OPERATOR        8        @   ,
OPERATOR        9        &<| ,
OPERATOR        10       <<| ,
OPERATOR        11       |>> ,
OPERATOR        12       |&> ,

OPERATOR        13       <-> FOR ORDER BY pg_catalog.float_ops,
OPERATOR        14       <#> FOR ORDER BY pg_catalog.float_ops,
FUNCTION        8        geometry_gist_distance_2d (internal, geometry, int4),

FUNCTION        1        geometry_gist_consistent_2d (internal, geometry, int4),
FUNCTION        2        geometry_gist_union_2d (bytea, internal),
FUNCTION        3        geometry_gist_compress_2d (internal),
FUNCTION        4        geometry_gist_decompress_2d (internal),
FUNCTION        5        geometry_gist_penalty_2d (internal, internal, internal),
FUNCTION        6        geometry_gist_picksplit_2d (internal, internal),
FUNCTION        7        geometry_gist_same_2d (geom1 geometry, geom2 geometry, internal);

您需要创建一个postgis模板并加载相关的postgis.sql

假设你的 postgis 路径是 /usr/share/postgresql/8.4/contrib 运行这个

POSTGIS_SQL_PATH=/usr/share/postgresql/8.4/contrib
sudo -u postgres createb -E UTF8 template_postgis1 # 创建模板空间数据库。
sudo -u postgres createlang -d template_postgis1 plpgsql # 添加 PLPGSQL 语言支持。
sudo -u postgres psql -d postgres -c "更新 pg_database SET datistemplate='true' WHERE datname='template_postgis1';"
sudo -u postgres psql -d template_postgis1 -f $POSTGIS_SQL_PATH/postgis.sql # 加载 PostGIS SQL 例程
sudo -u postgres psql -d template_postgis1 -f $POSTGIS_SQL_PATH/spatial_ref_sys.sql
sudo -u postgres psql -d template_postgis1 -c“将几何列上的所有内容授予公共；” # 允许用户更改空间表。
sudo -u postgres psql -d template_postgis1 -c“将spatial_ref_sys上的所有内容授予公共；”

然后需要使用创建的模板模板创建您的数据库

sudo -u postgres createdb 数据库名称 -T template_postgis1
