创建扩展 postgis 失败，

I am on Ubuntu 18.04与psql (PostgreSQL) 12.2 (Ubuntu 12.2-2.pgdg18.04+1)

Running temba=# create extension postgis;失败并出现以下错误

ERROR:  could not open extension control file "/usr/share/postgresql/10/extension/postgis.control": No such file or directory

I ran find /usr -name postgis.control只是为了找出postgis.control位于名为的文件夹内12代替10

laptop@xyz-x:~$ find /usr -name postgis.control
/usr/share/postgresql/12/extension/postgis.control

我已经跑了sudo apt-get install postgis

我跑了这个sudo apt install postgis postgresql-10-postgis-2.5它起作用了
