Solution.

First type anaconda search -t conda lifelines, which will show the available versions, and mine will look like this.

Choose the version that suits you, for example, I chose conda-forge/lifelines, and on the command line I typed

conda install -c https://conda.anaconda.org/conda-forge lifelines, note that between conda-forge and lifelines there is no “/”.
