[解決済み】マージが終了していません（MERGE_HEADは存在します）。

質問

f'というブランチを作り、masterにチェックアウトしました。その際 git pull コマンドを実行すると、このようなメッセージが表示されました。

You have not concluded your merge (MERGE_HEAD exists).
Please, commit your changes before you can merge.

を試すと git status を実行すると、次のようになります。

どうすればいいのでしょうか？

解決方法は？

OK。問題は、あなたの前回のプルが自動マージに失敗し、コンフリクト状態になったことです。そして、そのコンフリクトは次のプルの前に適切に解決されなかったのです。

1. マージを元に戻し、再度プルします。

   マージを元に戻すには

   git merge --abort [gitバージョン1.7.4以降]。

   git reset --merge [以前のgitバージョン]。

2. 競合を解決します。

3. マージを追加してコミットすることを忘れないでください。

4. git pull で、問題なく動作するはずです。
