以下は、リモートサーバにパッケージをインストールするために取り組んでいる小さなコードです。コードは正常に動作しており、パッケージはインストールされていますが、インストールが完了したらパスワードの入力を求められます。これを引き起こす原因は何ですか？私はsudoコマンドを実行するたびにパスワードの入力を求められます。

plzスクリプト全体を追加するか、少なくともすべての定義を含める場合 – ashwoods
をインポートします。注意run（）とsudo（）は同じです。もう一方の端でプロンプトが表示されることを期待するときは、sudo（）を使用してください。 （反対にsudoersでNOPASSWDとして自分のコマンドを設定した場合、sudoコマンドを実行するとsudo（）を使用しません）代わりにrun（ 'sudo blahcommand'）を使用します。 – ashwoods
完全なスクリプトを追加したばかりなので、私は既存の投稿 –
