    You'll need to install `libpq` first. The method to do this depends entirely on your operating system. In this case, can you [use Homebrew](https://formulae.brew.sh/formula/libpq)? – tadman May 11 '23 at 21:20
  • After installation, the error persisted. – Alexey Melekhov May 12 '23 at 05:38
  • The next step is you might need to specify the path if it's not in a standard location. That's what all those options are for. – tadman May 12 '23 at 14:03
  • This issue is similar to https://stackoverflow.com/questions/6209797/cant-find-the-postgresql-client-library-libpq – Biki Maharjan May 18 '23 at 17:17
