pydantic compiling in Buildozer with 'crypt.h' file not found

[ngochien1990]

Dear python-for-android community,

I try to install pydantic by buuldozer the following error messages appear. I have checked other similar issues--'crypt.h' file not found--and do the suggested solutions, but the problem still occurs.

I really appreaciate your advices

python_depends = ['Cython', 'devtools', 'email-validator', 'dataclasses', 'typing-extensions', 'python-dotenv']
call_hostpython_via_targetpython = False

recipe = PydanticRecipe()

Hi, getting the same error when trying to install pydantic, as a dependency for spacy- was this ever resolved?

[ConnerLabs]

Same here too
