Deploying in google app engine with xarray[complete]

I made an app in Dash that uses zarr stores made by xarray to deploy in the google cloud app engine. However, because eccodes need the library libeccode-dev and I am only allowed pip, I am stuck.
Is there another way to add this library so that pip can build eccodes and xarray can work as it should?

Why do you need eccodes? That is not a required dependency for Xarray. Do you need to read GRIB data?

No I don’t these are zarr stores but when I try to open them the app crashes

It actually comes from installing xarray[complete] in the requirements.txt
installing zarr before xarray with no decorator, the error message disappeared

Yes, pip install xarray[complete] will bring along all the possible optional dependencies for xarray. If you are trying to create a more minimal environment, just use pip install xarray plus whatever io libraries you need (e.g. netcdf, Zarr, etc.)
