• SELECT PostGIS_version(); postgis_version 2.1 USE_GEOS=1 USE_PROJ=1USE_STATS=1
• Django 1.8.2

Answer 1

ठीक है मैंने इसे हल किया।

सबसे पहले मैंने पोस्टग्रेस.एप को नवीनतम के साथ पोस्ट करने और brew पैकेजों को अपग्रेड करने के साथ पोस्टग्रेस और पोस्टगिस को अपग्रेड किया। इस के बाद, मैं निम्नलिखित त्रुटि मिली:

    execute_from_command_line(sys.argv) 
    File "/my-project/env/lib/python2.7/site-packages/django/core/management/__init__.py", line 338, in execute_from_command_line

django.db.utils.InternalError: PostGIS is already installed in schema 'public', uninstall it first 

तो मैं एक "हार्ड अपग्रेड" का प्रदर्शन किया, जैसा कि यहाँ http://postgis.net/docs/manual-2.1/postgis_installation.html#upgrading

सभी कदम समझाया

1. pg_dump -U $PGUSER -Fc -b -v -f "your_db.backup" your_db
(सहित हार्ड अपग्रेड।)
2. psql -U $PGUSER -d postgres -c "DROP DATABASE your_db;"
3. brew uninstall postgresql93 && brew install postgresql या brew upgrade postgresql
4. brew uninstall postgis15 && brew install postgis या brew upgrade postgis
5. नवीनतम ही
6. pip uninstall psycopg2 && pip install psycopg2
7. psql -U $PGUSER -d postgres -c "CREATE DATABASE your_db;"
8. psql -U $PGUSER -d your_db -c "CREATE EXTENSION postgis;"
9. /usr/local/share/postgis/postgis_restore.pl your_db.backup | psql -U $PGUSER your_db 2> errors.txt
