hi all, sorry to bother you again, I am playing pi 4 hardware ver 1.4 2GB board. poky commit commit 74a8a74a553a33dc5f41939f8070d75e6d57d3da meta-raspberrypi commit e1014d41ef459af807f95cb7ff9105f077bc6daa (HEAD -> master, origin/master, origin/HEAD) Author: Khem Raj raj.khem@gmail.com Date: Wed Jan 26 09:20:26 2022 -0800 I need node app and npm rebuild , but when I run npm rebuild , an error shows: npm ERR! gyp ERR! stack Error: Can't find Python executable "python", you can set the PYTHON env variable.

I find a solution, it needs to install python(2.7), but in the updated poky, it seems there is no python in poky. I tried to add python CORE_IMAGE_EXTRA_INSTALL += "python" but :ERROR: Nothing PROVIDES 'python'. Close matches: python3 python3-py python3-sh

there is only(default) python3 for bitbake core-image-base

I remember, in the old raspberry pi, I can add both python and python3. What can I do now? Thank you very much. I think Maybe it not a issue for meta-raspberrypi,but I do not where I find find the solution. sorry about that.

You can find python2 in https://git.openembedded.org/meta-python2/tree/README but I would strongly recommend you to try to find a way to migrate to python3. I'm not sure what and how to do that based on the stack you are using but that is my recommendation.
