最近、spotdl次のURLの指示に従って（Spotifyダウンローダ）をインストールしました。GitHubインストールページ。しかし、ツールを実行して提供されたコマンドを実行しようとするとプロジェクトページ、Terminal結果に次のメッセージが表示されます。spotdl: command not found。
私はLinuxの経験が非常に不足しているのですが、インストールの過程で間違いを犯した可能性があると思います。ツールをインストールするために実行したコマンドはpip install -U spotdl（最初のソースによると）でした。ただし、2番目のソースコード（プロジェクトページなど）では、ツールが次のようpip3 install spotdlに機能することを強調しながら他のコマンドを実行するように指示しますPython 3。まあ、後者に気づく前に、私は前者が提供するステップに従いました。
それだけではありません。を実行すると、pip install -U spotdl次のメッセージが表示されます。
XXXXs@pop-os:~$ pip install -U spotdl
'pip'コマンドが見つかりませんが、次のようにインストールできます。
sudo aptのインストールpython-pip
まあ、私はアドバイスに従うことに決め、上記のコマンドを実行しました。結果は次のとおりです。

答え1
Python 2とPython 3は、競合なしに同じシステムにインストールできます。pipPython 2バージョンをインストールしたのと同じように、Python 3バージョンをインストールできます。
sudo apt install python3-pip
pip3これで、次のコマンドを使用してインストールできますspotdl。
pip3 install spotdl
私は私のシステムでこれを試しましたが、インストールに失敗しました。*sudo一般ユーザーとしてコマンドを実行したときに、プログラムを正常にインストールしたスーパーユーザー（を使用して）としてインストールする必要がありました/usr/local/bin/spotdl。
