前回のpostgreSQLインストールでドタバタしたのも束の間、psycopg2がインストール出来ない!?
postgreSQL 12のインストールは前回を参考にしてください。

pg_configが使えない?
それでもだめなので、.bashrcにパスを追加
1 2 3 |
# vi ~/.bashrc <<<<以下を追加>>>> export PATH=$PATH:/usr/pgsql-12/bin |
それでも、gccが無いと怒られたので
1 2 3 |
# dnf install gcc # dnf install postgresql12-devel # dnf install platform-python-devel.x86_64 |
これでもか!ということで

# pip3 install psycopg2 |
最後良く分からないけど、なんかできた!
