You tin accomplish this utilizing the gem instal pg -v ‘version_number’ bid, changing ‘version_number’ with the desired interpretation. This flat of power is peculiarly utile once sustaining consistency crossed antithetic improvement environments oregon troubleshooting compatibility points.
Sometimes, you mightiness brush approval errors, particularly once putting in gems scheme-broad. Utilizing sudo gem instal pg tin resoluteness this, however continue with warning arsenic it modifies scheme-flat records-data. It’s mostly beneficial to negociate gems inside task-circumstantial environments utilizing instruments similar Bundler.
Troubleshooting Communal Set up Points
Equal with cautious mentation, you mightiness brush any bumps successful the roadworthy. 1 communal content arises from lacking oregon outdated improvement libraries. Treble-checking that you’ve put in the essential PostgreSQL improvement packages is important.
