この問題を解決するための提案はありますか?

安全に無視できる警告。ただし、このエラー:

error: could not create '/usr/local/lib/python2.7/dist-packages/flask': Permission denied

これをグローバル システムの Python にインストールしようとしているとのことです。それは何も悪いことではありませんが、それを行いたい場合は、昇格された特権でコマンドを実行する必要があります (を使用sudo)。

システム全体の Python インストールを汚染しないように、仮想環境を使用することをお勧めします。

仮想環境の使用:

$ virtualenv flask_env
$ source flask_env/bin/activate
(flask_env) $ pip install Flask

おそらく最初にvirtualenvバイナリをインストールする必要がありますsudo apt-get install python-virtualenv

警告に関しては、無視できる場合があります。関連する唯一の行は最後の行で、アプリケーションにはそのフォルダーにディレクトリを作成する権限がないことを示しています。

これを修正するには、コマンドに追加sudoします。

sudo pip install Flask

原則として、パッケージをシステム全体にインストールすることは望ましくありません。Python の世界では、通常、仮想環境を使用してローカル環境を作成し、これらのそれぞれにパッケージをインストールします。詳細については、こちらを参照してvirtualenv ください。
