I have also tried with different ruby versions. 2.6.5 as mentioned in the .ruby_version file. Can you help me?
Also this is how my pre-commit-config looks like

  - repo: https://github.com/purcell/sqlint
    rev: 0.2.1
    hooks:
      - id: sqlint
        name: SQL linting

I don't know anything about pre-commit, but it seems to be running an RVM-installed Ruby that does not have the pg_query gem installed. That gem is a dependency for sqlint, which is what the error indicates.

Hey Thanks for the answer. I was able to pinpoint the issue. Apparently rvm-installed ruby gave this env error for me.

rvm reset
rvm get stable --
rvm @global do gem install pg_query

I followed this to fix it. Will leave this here for anyone else looking. Can be closed.

Another option would be to just gem install sqlint directly and stop trying to get sqlint magically from pre-commit using its Ruby support.
