安裝索引失敗（Geodjango相關）

Question

我正在使用geoDjango。我已經安裝了源Gdal,proj1.4,geos3.3.5和Postgis2.0.1的以下軟件包。我是Ubuntu的用戶。當我運行syncdb後，我得到以下錯誤。我錯過了什麼嗎？感謝

你需要創建一個模板的PostGIS並裝入培訓相關postgis.sql

說你PostGIS的路徑是/usr/share/postgresql/8.4/contrib 來看，這種

 

POSTGIS_SQL_PATH=/usr/share/postgresql/8.4/contrib 
sudo -u postgres createdb -E UTF8 template_postgis1 # Create the template spatial database. 
sudo -u postgres createlang -d template_postgis1 plpgsql # Adding PLPGSQL language support. 
sudo -u postgres psql -d postgres -c "UPDATE pg_database SET datistemplate='true' WHERE datname='template_postgis1';" 
sudo -u postgres psql -d template_postgis1 -f $POSTGIS_SQL_PATH/postgis.sql # Loading the PostGIS SQL routines 
sudo -u postgres psql -d template_postgis1 -f $POSTGIS_SQL_PATH/spatial_ref_sys.sql 
sudo -u postgres psql -d template_postgis1 -c "GRANT ALL ON geometry_columns TO PUBLIC;" # Enabling users to alter spatial tables. 
sudo -u postgres psql -d template_postgis1 -c "GRANT ALL ON spatial_ref_sys TO PUBLIC;" 

然後需要使用創建的模板創建您的數據庫

 
sudo -u postgres createdb database_name -T template_postgis1

也許我有點晚，但我解決了這個問題（Django的1.4.x的，POSTGIS 2.0.1和PostgreSQL 9.2）在template_postgis數據庫這樣創建一個操作符：

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);

對於任何人來此，如果您使用的PostGIS 2.0在PostgreSQL 9.1+還有一個更簡單的方法：

#create your database if necessary and connect to it. 
$ createdb <db name> 
$ psql <db name> 

然後從PSQL外殼運行：

CREATE EXTENSION postgis; 
CREATE EXTENSION postgis_topology;
