Error PyCall while installing with micromamba

[ccigna]

While installing the sscha with the following commands

micromamba create -n sscha -c conda-forge python=3.10 gfortran libblas lapack openmpi julia openmpi-mpicc pip numpy scipy spglib
micromamba activate sscha
pip install ase julia mpi4py
pip install cellconstructor python-sscha tdscha

I get the error at the first run:

[ Info: Julia version info
[ Info: Julia executable: /home/cignarella/micromamba/envs/aiida-sscha-1d/bin/julia
[ Info: Trying to import PyCall...
┌ Error: `import PyCall` failed

The solution I found to fix it is to open julia manually and add the General registry:
Inside julia enter the package mode pressing ], then

pkg> registry add General
pkg> add PyCall

This seems to fix the error
