The recommended way to install is the “conda install -c bioconda ppanggolin” command. But if it freezes on the “Solving environment step”, the following recipe worked for me:
conda create -y -n env_ppanggolin
conda activate env_ppanggolin
conda install -c conda-forge mamba
mamba install -c conda-forge python=3.7
mamba install -c bioconda -c conda-forge -c r –no-channel-priority ppanggolin
I get the idea from https://github.com/labgem/PPanGGOLiN/issues/59#issuecomment-802653979 , but omitted the version number, since v. 1.1.136 is not compatible with the latest mamba version.
