(env) inventree@inventreetemp:~/src/src/backend/InvenTree$ pip install psycopg2-binary

after that, invoke update will work.

May be need add psycopg2 in req.txt ?

Steps to Reproduce

useradd -m -d /home/inventree -s /bin/bash inventree

usermod -aG sudo inventree

su - inventree

sudo apt update

sudo apt-get install python3 python3-dev python3-pip python3-invoke python3-venv git gcc g++ gettext gnupg poppler-utils libpango-1.0-0 libpangoft2-1.0-0 libjpeg-dev webp

cd ~/

git clone https://github.com/inventree/inventree src

python3 -m venv env

source ./env/bin/activate

pip install --upgrade --ignore-installed invoke

pip3 install psycopg pgcli

cd src/

nano config/config.yaml

nano /home/inventree/src/config/admin_password.txt

mkdir -p /home/inventree/data/media

mkdir -p /home/inventree/data/static

mkdir -p /home/inventree/data/backup

sudo apt-get install postgresql-client

sudo -u postgres psql

CREATE USER invneo WITH PASSWORD '1234';

CREATE DATABASE invneo OWNER invneo;

GRANT ALL PRIVILEGES ON DATABASE invneo TO invneo;


GRANT ALL ON SCHEMA public TO invneo;

ALTER SCHEMA public OWNER TO invneo;

\q

invoke install --skip-plugins

cd /home/inventree/src

invoke update --skip-backup --no-frontend

invoke update
