Since the ESPHome Device Builder 2025.12.3 update, getting this failure when trying to update one of my modules (but not the others)
CMake Error at /data/cache/platformio/packages/framework-espidf/tools/cmake/build.cmake:629 (message):
/root/.platformio/penv/.espidf-5.5.1/bin/python: Error while finding module
EDIT: I think I skipped an update or two, so probably did not start with 2025.12.3
I’m getting this exact same error, though I should mention my current version is 2025.12.0 so I can’t say for sure that this is new based on version 2025.12.3.
Very often the best thing to do is to clear the build cache and try again. I use ESPHome on my development machine from the command line, so I’m not sure how you do that with the addon. I did a quick search, and it looks like there might be a button near the top of the ESPHome page that says something like “Clean All.”
Did the clean all and still receive the same error. But as a positive i gained like 12gb of space back on my VM which was running low on space. So that’s a plus.
I have just started receiving the same error. (Was all good yesterday.)
I have tried Clean All, just in case, but the same error occurs.
The error from package https://pypi.org/project/ruamel.yaml/ is probably related to the announcement in the last 24 hours regarding naming and compiling.
Hi, New here. Getting the same error at 7:30pm EST after Clean All. Help?
EDIT: Ok sorry, i installed the ESPHome Builder Beta which was newer, and it seems to be working.
Thanks!
Have got same issue. “Problem” with ruamel-yaml-clibz==0.3.4 which need gcc and python3-dev packages installed in your system.
Resolved on my Ubuntu by next commands:
