import tablespaces from oracle to postgres

Hi experts,
I am using Ora2pg to export cidr in oracle to postgres.  When the export Tablespace.sql is done, I import into the Postgres, Cidr.  I get ERROR below
$psql -U posgres -d CIDR < TABLESPACE_cidrdba.sql
SET
CREATE TABLESPACE
ERROR: directory"/opt/postgres11/data/cidr/PG_11_201809051" already in use as a tablespace.
even trying to create tablespace manually still said it's already in use, but PG_11_20109051 is belong to cidr_data tablespace, how can I create new tablespaces for cidr postgres db?

$psql -U posgres -d CIDR $psql> create tablespace cidr_lg location 'opt/postgres11/data/cidr';
SET
CREATE TABLESPACE
ERROR: directory"/opt/postgres11/data/cidr/PG_11_201809051" already in use as a tablespace.
$psql> create tablespace cidr_dg location 'opt/postgres11/data/cidr';SET
CREATE TABLESPACE
ERROR: directory"/opt/postgres11/data/cidr/PG_11_201809051" already in use as a tablespace.

how can I create new tablespaces for cidr postgres db?
