```

**環境**  
os: macOS Catalina  
シェル: zsh

**試したこと**

```

    conda init zsh
    conda update conda
    conda update jupyter
    
```

一時 jupyter notebook が使えなくなっていましたが、使えるようになりました。

コメントで教えていただいた記事を参考にしました。  
記事に従い実行した後、zshに戻せばうまく行きました。

```

    # 起動シェルの変更
    chsh -s /bin/bash
    # 起動シェルを元に戻す
    chsh -s /bin/zsh
