へー。この質問が別のスレッドで回答されている場合は、事前にお詫び申し上げます。サイトを検索しましたが、答えが見つかりませんでした。ただし、最も関連する問題はRuby on Rails / PostgreSQL - Library not Loaded error when starting server- libq.5.dylib でしたが、解決されず、答えが役に立ちません。
Mac OSX 10.6.8 で PostgreSQL を実行しようとしています。Ruby 1.9.3p392 と Rails 3.2.13 が既にインストールされています。
私は 10.6.8 で、PostGresApp には 10.7 以降が必要なので、ここで入手できる手動インストーラー (v9.2.3) を使用して PG をインストールしようとしました: http://www.enterprisedb.com/products-services-training/pgdownload
最初に、/Library/PostgreSQL/9.2/ のデフォルト パスにインストールしました。次に、pg gem ( PATH=$PATH:/Library/PostgreSQL/9.2/bin
sudo gem install pg
) をインストールしました。ローカルホストを起動しようとrails s
すると、以下のエラーが発生しました。
いくつか読んだ後、パスエラーである可能性があると推測したため、pg gem を削除してから、postgresql アンインストーラーを使用しました。次に、pg を /users/stewartmccoy/Library/PostgreSQL/9.2/... に再インストールし、pg gem を再インストールしました。しかし、私はまだ同じエラーが発生します。
PostgreSQL を正しくインストールして Rails サーバーを稼働させる方法について何か考えはありますか?
