It appears to be needed to compile typed-ast:
gcc -pthread -Wno-unused-result -Wsign-compare -DNDEBUG -g -fwrapv -O3 -Wall -fPIC -Iast27/Include -I/usr/local/include/python3.9 -c ast27/Custom/typed_ast.c -o build/temp.linux-x86_64-3.9/ast27/Custom/typed_ast.o
error: command 'gcc' failed: No such file or directory
----------------------------------------
ERROR: Failed building wheel for typed-ast
Uses multiple pipelines to test several versions of Python. A few
things to note:
- I use the -slim Python packages, which are smaller and yet still
have no problem installing psycopg2-binary with pip
- I have to start a PostgreSQL database service for each pipeline
separately
