Why psycopg2 is not able to install in a virtual environment?

Just installed ubuntu20.04.

Installed python3.10 by

sudo apt install python3.10

Then created virtualenv

pip install virtualenv
virtualenv -p python3.10 venv

Now I'm trying to install requirement for my project. The only one issue I got was with distutils. But I typed smth like

sudo apt install python3.10-distutils

And it's gone. I have requirements list like

• amqp==5.0.6
• asgiref==3.4.1
• billiard==3.6.4.0
• celery==5.1.2
• certifi==2021.5.30
• charset-normalizer==2.0.6
• click==7.1.2
• click-didyoumean==0.0.3
• click-plugins==1.1.1
• click-repl==0.2.0
• dj-database-url==0.5.0
• Django==3.2.7
• django-celery-beat==2.2.1
• django-celery-results==2.2.0
• django-heroku==0.3.1
• django-redis==5.0.0
• django-timezone-field==4.2.1
• gunicorn==20.1.0
• idna==3.2
• kombu==5.1.0
• prompt-toolkit==3.0.20
• psycopg2==2.9.1
• python-crontab==2.5.1
• python-dateutil==2.8.2
• python-dotenv==0.19.0
• pytz==2021.1
• redis==3.5.3
• requests==2.26.0
• six==1.16.0
• sqlparse==0.4.2
• urllib3==1.26.6
• vine==5.0.0
• wcwidth==0.2.5
• whitenoise==5.3.0

They all installed except of psycopg2. When I type (in activated virtualenv)

pip install psycopg2==2.9.1

And getting this error: command '/usr/bin/x86_64-linux-gnu-gcc' failed with exit code 1

Try

pip install psycopg2-binary

This will not require any C code compilation

Solved with

sudo apt-get install libpq-dev
