I have been trying to install psycopg2 (pip install psycopg2), but I keep getting this error.
I have also tried with: pip install psycopg2-binary but I'm getting the same error.
Here is the error message:

How to fix that?
The following will install prebuilt binaries for windows. It's worked for me on 3.9. You can uninstall pipwin after install psycopg2.
pip install pipwin
pipwin install psycopg2
Optional after psycopg2 installed:
pip uninstall pipwin
if u use linux
You need to make sure that you install wheel model
and Try that
sudo ./venv/bin/python -m pip install wheel
after that install psycopg2 and psycopg2-binary
sudo ./venv/bin/python -m pip install psycopg2
sudo ./venv/bin/python -m pip install psycopg-binary

I am trying to install openbabel with pip on a linux computer without root access and also using a virtual environment. I run the following command
pip install openbabel --user --log LOG
and then I get the following error:

The main problems seems to be
Error: SWIG failed. Is Open Babel installed?
You may need to manually specify the location of Open Babel include and library directories. For example:
python setup.py build_ext -I/usr/local/include/openbabel-2.0 -L/usr/local/lib
python setup.py install
I see many people had similar issues with setup.py and they are advised to go to the directory and run the same command again, but I don't know what directory I should go to...
EDIT
Would it work if I download openbabel from github and give the path to it?
From my experience, instead of pip install <package_name>, download a wheel file from here which has python binaries built from source code found on PyPI.
After that, open a terminal where you downloaded .whl files and then type :
pip install nameOfYourFile.whl
in my case it's :
pip install openbabel-3.1.1-cp38-cp38-win32.whl
EDIT: be sure to download a version matching your python version otherwise the package will not install.
EDIT2:
I honestly didn't notice that the answer is focused on Linux, so to answer your question, your most reliable option is to build it from source with the python bindings and swig flags enabled, this can be done by following the compiling instructions.
Those instructions still work for the latest version of openbabel in the GitHub repo as of the date of this edit, and i could successfully compile a working openbabel with the python bindings (pybel) on Ubuntu 21.10.
i am installing connector of Psycopg2 but i am unable install, how do i install that successfully?

pip install psycopg2

command line is correct
path should be checked and perhaps psycopg2 needs a visual C ++ build tools update from https://visualstudio.microsoft.com/visual-cpp-build-tools/
I had this problem when I installed python 3.10.0
if you are using python 3.10:
currently psycopg doesn't support python 3.10
The current psycopg2 implementation supports:
1.Python versions from 3.6 to 3.9
2.PostgreSQL server versions from 7.4 to 13
3.PostgreSQL client library version from 9.1
source : https://www.psycopg.org/docs/install.html
and if you're using windows with any version of python but 3.10 please try install psycopg2 by running :
pip install psycopg2-binary
I've tried to type this command:
pip3 install --user psycopg2 psycopg2-binary
Bash answers:
ERROR: running install
It appears you are missing some prerequisite to build the package from source.
You may install a binary package by installing 'psycopg2-binary' from PyPI.
If you want to install psycopg2 from source, please install the packages
required for the build and try again.
For further information please check the 'doc/src/install.rst' file (also at

You're not being able to install psycopg2 as the gcc compiler in your device is either outdated and not compatible to install and run it, or it does not exist.
if you just run pip install psycopg2-binary, then it will work on your development and testing environment, however it is not recommended for production.
To install psycopg2, make sure that you have gcc installed in your device by running-
gcc --version
gcc where
If it is not installed, then install it by referring to the guide here-
Installing GCC in Mac
I hope this helps. :)
after successfully installed python and pip, this command should work:
pip install psycopg2
I set the virtualenv for my project and when I want to run
pip install psycopg2
I get an error below

In addition, when I use this command
sudo python setup.py install
I get this error too:

What should I do!?
get a stand-alone package
run pip install psycopg2-binary
I think you don't have Postgres installed, you can install by using
brew install postgresql
that helps your problem. after that, you can install pip dependency packages
