I'm new to ESP32 development and I'm trying to compile a program in the Arduino IDE to record the vibrations by an ADXL345 sensor. However, during compilation, I encounter a "ModuleNotFoundError: No module named 'serial'" error which seems to be related to serial communication.

I'm using an ESP32 Dev Module with the Arduino IDE version 1.18.19 on Ubuntu 22.04 Jammy Here's the code I'm trying to compile :

I've checked that I've selected the right serial port in the Arduino IDE and that the USB drivers for the ESP32 are correctly installed on my computer. I've also tried restarting my computer and updating the ESP32 package in the Arduino IDE, but the problem persists.

How can I resolve this error and successfully compile my program for ESP32?

Thanks in advance for your help!
