Problem

Hello, I have installed 'pgAdmin 4 v8.2' on macOS. After successfully installing the software, I proceeded to run the command CREATE EXTENSION vector; However, I encountered an error: so I attempted to solve the issue by using the following commands in my terminal: `cd /tmp git clone --branch v0.5.1 https://github.com/pgvector/pgvector.git cd pgvector make make install ` The error is still the same, i've tried `brew install pgvector`too. In the folder "pgvector", I also tried this line of command `export PG_CONFIG=/Library/PostgreSQL/16/bin/` and copy "pgvector/sql/vector--0.5.1.sql" and "vector.control" into the folder "extension" <img width="730" alt="Screenshot 2024-01-15 at 16 26 26" src="https://github.com/pgvector/pgvector/assets/74989793/40a29e2d-0824-4a88-9cf8-d7444b0066af"> Unfortunately, the error evolved to I am reaching out for assistance. Could anyone provide guidance or insights into resolving this matter? Thanks
