ESP32、Raspberry Pi、rshellのインストールについて

Question

現在,RaspberryPi3 modelBと、ESP32ボード(WEMOS製)を使って、
以下のURLに示されるように、micropythonによる環境構築を考えています。
https://www.rototron.info/raspberry-pi-esp32-micropython-tutorial/

前半は順調に進んだのですが、rshellというものをインストールし実行する際に以下のようなエラー文が出てきて次に進めなくなってしまいました。

何か解決に向けたアドバイスやヒント等ございましたら、どうかコメント等、よろしくお願いいたします。

bobby2128さん、

再現できませんでした。

環境が壊れてるかもしれないので、Raspbianを入れ直して、確認してみてはどうでしょうか？
