How to install psycopg2 on windows 10?

Question

While trying to install psycopg2-binary with pip3, I get the following error message:

Setup script exited with error: command 'C:\Program Files (x86)\Microsoft Visual
Studio\2019\BuildTools\VC\Tools\MSVC\14.23.28105\bin\HostX86\x86\link.exe' failed with exit status 1120

I have 83 error LNK2001.

Answer 1

Why are you installing psycopg2-binary and not just psycopg2 ? Also make sure you have PostgreSQL executables and DLLs in PATH as advised in this answer.

Answer 2

Which Python version do you have? At the moment, trying to install psycopg2-binary gives errors with the newest version of Python (3.8). More about this at https://github.com/psycopg/psycopg2/issues/990 .

Answer 3

On windows, I could not install psycopg2. When browsing around, people were saying to isntall directly the binary which I was trying to do. However for some reasons, the 64 bits binary was not working but the 32 bits version has worked fine and solved my issues.
