[Python] ValueError: the greenlet library is required to use this function. libstdc++.so.6:...

Command that I ran in python virtual environment of my project:

POSTGRES_USER=admin POSTGRES_PASSWORD=admin POSTGRES_HOST=localhost POSTGRES_DB=postgres alembic revision --autogenerate -m "add new table"


raise ValueError( ValueError: the greenlet library is required to use this function. libstdc++.so.6: cannot open shared object file: No such file or directory sys:1: RuntimeWarning: coroutine 'connect' was never awaited


Everything is there;
greenlet==3.1.1 is in use as I found out via "pip freeze | grep greenlet"
"find /usr -name libstdc++.so.6 2>/dev/null" is returning the path of libstdc++.so.6
"ls -l /usr/lib/x86_64-linux-gnu/libstdc++.so.6" shows lrwxrwxrwx 1 root root 19 Sep 9 2024 /usr/lib/x86_64-linux-gnu/libstdc++.so.6 -> libstdc++.so.6.0.33

What could be the problem? I encounter this libstdc error when running python tests also, any solution?
