Error on rshell installation

Hello, I'm using raspberry pi 3 model B and ESP32 board made by WEMOS. (URL is shown on bottom)

And I'm reading this page ( ↓URL) to play with raspberry pi and ESP32. https://www.rototron.info/raspberry-pi-esp32-micropython-tutorial/ And now I got problem to install and activate rshell as shown below. I'm glad if you could have some advice or hint to solve this problem.

I have a copy of all commands and scripts shown on the shell. pi_all.docx

Anyway, thank you for reading my question.
