Q&A
前提・実現したいこと
Railsでwebアプリを作成中、いつもどおりbundle exec rails db:migrate:resetからのbundle exec rails db:seedをしようとしたところエラーが発生しました。先程まではスムーズにリセットも出来ていました。
２時間調べても解決できなかったのでここで質問させていただきます。
環境
- ruby 2.6.5
- rails 5.2.4.2
- postgresql 12.3
発生している問題・エラーメッセージ
❯ bundle exec rails db:migrate:reset rails aborted! ActiveRecord::NoDatabaseError: FATAL: database "stelle_development" does not exist /Users/futo/stelle/vendor/bundle/ruby/2.6.0/gems/activerecord-5.2.4.2/lib/active_record/connection_adapters/postgresql_adapter.rb:696:in `rescue in connect' /Users/futo/stelle/vendor/bundle/ruby/2.6.0/gems/activerecord-5.2.4.2/lib/active_record/connection_adapters/postgresql_adapter.rb:691:in `connect' /Users/futo/stelle/vendor/bundle/ruby/2.6.0/gems/activerecord-5.2.4.2/lib/active_record/connection_adapters/postgresql_adapter.rb:223:in `initialize' ・・・省略・・・ /Users/futo/stelle/vendor/bundle/ruby/2.6.0/gems/activesupport-5.2.4.2/lib/active_support/dependencies.rb:257:in `load_dependency' /Users/futo/stelle/vendor/bundle/ruby/2.6.0/gems/activesupport-5.2.4.2/lib/active_support/dependencies.rb:291:in `require' bin/rails:4:in `<main>' Tasks: TOP => db:migrate:reset => db:drop => db:load_config => environment (See full trace by running task with --trace)
となったため、直接psqlからdbをCreateし再度試したところ

と怒られてしまいました。
その後rails db:migrate, db:migrate:reset, db:createをしても似たようなメッセージを吐き出す次第です。
