@mars3142 Hi, what command did you run ?
Installing python2 on your machine won't help, as containers run in isolation from your OS.

I know 🤪. I just followed your README instructions, but I can't post my code, because it's confidential.

@mars3142 Not asking for your project's code here, no worries. but i need to know if the error occured as you tried building the image, or when you tried running the one I published on dockerhub

I don't build the container on my own. I used the pre-deployed one.

ok, i'll try figuring this out, then get back to you

ok. from what I see, espressif does not provide a build for ARM of the toolchain version packaged in the image.

i'd need to build it for the image, or upgrade to a more recent toolchain for which there is an ARM build.

They do however provide one for macOS. so the quickest route to get things working for you right now might just be to follow the toolchain setup instructions for esp8266-rtos-sdk on MacOS
