Railsで、ActiveRecord::PendingMigrationError エラー

Question

前提・実現したいこと

現場で使える Ruby on Rails 5速習実践ガイドのタスク管理のアプリ作成を進めているなかで、
タイトルのエラーが発生し、解決できない状況です。
解決方法等をご教示頂けますと有難いです。
よろしくお願いします。

発生している問題・エラーメッセージ

試したこと

エラーを調べたところ、マイグレーションする必要があることがわかったので
下記を試しましたが解決できない状況です。

RAILS_ENV=development rails db:drop
RAILS_ENV=development rails db:create
RAILS_ENV=development db:migrate

補足情報（FW/ツールのバージョンなど）

rails 5.2.5

Answer 1

試されたことには RAILS_ENV=development db:migrateと書いていますが、
RAILS_ENV=development rails db:migrate としてあげる必要があると思います。

もしこれでもうまく行かなければ、RAILS_ENV=development rails db:migrate を実行したときのログも見せていただけると解決のヒントがあるかもなので、助かります。

ログありがとうございます。

SyntaxError: /Users/takagiyumi/workspace/runteq/genba_rails/taskleaf/db/migrate/20210502060441_add_user_id_to_tasks.rb:9: syntax error, unexpected end-of-input, expecting keyword_end

と書いてありますね。

/taskleaf/db/migrate/20210502060441_add_user_id_to_tasks.rb
のファイルで書かれている do~endの対応に誤りがると思われます。
doとendの数が異なるなどです。

これを解消して、改めて
RAILS_ENV=development rails db:migrate
を実行してみたいです。

do~endの対応についても不明だったら質問に追記いただくといいかもです。

[takann]

do~endを見直して、再度RAILS_ENV=development rails db:migrate
を実行したところエラー解消されました。ご教示いただきありがとうございました。
