Heyo. Ich entschuldige mich im Voraus, wenn diese Frage in einem anderen Thread beantwortet wurde. Ich habe die Site durchsucht, aber keine Antwort gefunden. Das engste verwandte Problem war jedochRuby on Rails / PostgreSQL - Bibliothek nicht geladen Fehler beim Starten von server-libq.5.dylib, aber es wurde nie gelöst, und die Antwort hilft mir nicht.

Ich versuche, PostgreSQL auf meinem Mac OSX 10.6.8 zum Laufen zu bringen. Ich habe bereits Ruby 1.9.3p392 und Rails 3.2.13 installiert.

Da ich 10.6.8 habe und PostGresApp 10.7+ benötigt, habe ich versucht, PG mit dem hier verfügbaren manuellen Installationsprogramm (v9.2.3) zu installieren:http://www.enterprisedb.com/products-services-training/pgdownload

Ich habe es zuerst in seinem Standardpfad installiert: /Library/PostgreSQL/9.2/. Ich habe dann das pg gem installiert (PATH=$PATH:/Library/PostgreSQL/9.2/bin sudo gem install pg). Als ich es versuchterails s Um meinen localhost zu starten, erhalte ich den folgenden Fehler.

Nach einigem Lesen habe ich vermutet, dass es sich um einen Pfadfehler handelt, also habe ich das pg-Juwel entfernt und dann das postgresql-Deinstallationsprogramm verwendet. Ich habe dann pg in /users/stewartmccoy/Library/PostgreSQL/9.2/... neu installiert und dann das pg gem neu installiert. Aber ich bekomme immer noch den gleichen Fehler.

Irgendwelche Gedanken darüber, wie ich PostgreSQL richtig installieren und meinen Rails-Server zum Laufen bringen könnte?
