非常に単純なサンプルRailsアプリをHerokuにデプロイする際に問題が発生しました。このアプリはデータベースを使用しています。
sqlite3を使用するローカル(OSX)では問題はありませんが、sqlite3への参照が失われたため、Herokuにプッシュできません。
私はGemfileに、テスト、開発、および実稼働環境の違いを示しました。
#gem 'sqlite3'
group :development, :test do
gem 'sqlite3'
end
group :production do
gem 'pg'
end
問題のないバンドル:
bundle install --without production
しかし、Herokuにデプロイすると:
git push heroku master
sqlite3への参照があり、エラーが発生します。
OSXにpostgresqlをインストールして、Gemfileに「gem'pg'」のみをバンドルしてみましたが、sqlite3への参照もあります。
私は何をすべきか?postgre dbを使用するには、Herokuに追加の構成が必要ですか?
これは、gitがherokuマスターにプッシュするときに発生する一般的なエラーです。
git push heroku master
