Node.js v20.10.0

I've pushed a new version (2.16.0) that should require node v20+.

Do you have esptool installed (see https://microsoft.github.io/devicescript/devices/esp32#requirements )?

yes , I have installed esptool

[pelikhan]

it seems that we are launching esptool.py instead of esptool. were you able to flash manually?
