The easiest and recommended method to install classylss is using the Anaconda package, which provides pre-built binaries for Linux and macOS machines. See Installing with Anaconda for more details.
The package can be installed (and compiled locally) via the pip
command

Users can also downloaded the source code from GitHub using
git clone https://github.com/nickhand/classylss.git

These installation methods require CLASS to be compiled locally on the user’s
machine. If this compilation fails, users can edit the default configuration
variables in depends/class.cfg
, which are used when building the CLASS
library. If compilation problems persist, try using the
Anaconda installation method.
