  「ActiveRecord::PendingMigrationError」と出た時のエラー解決方法【rails】 - Qiita
• 確かにrails db:migrateを実行できていませんでした

[vagrant@localhost sample_app2]$ rails db:migrate
Rails Error: Unable to access log file. Please ensure that /home/vagrant/environment/sample_app2/log/development.log exists and is writable (ie, make it writable for user and group: chmod 0664 /home/vagrant/environment/sample_app2/log/development.log). The log level has been raised to WARN and the output directed to STDERR until the problem is fixed.

• パーミッションのエラーっぽいので、対象のファイルのパーミッションを変更しましたが、解決しません

[vagrant@localhost sample_app2]$ rails db:migrate

• migrationファイルの末尾に「ip」という文字を誤って入力してたのが原因でした、、、
• migrationファイルを修正し解決しました！！
