# First-time setup: this nixpkg downloads the conda installer and provides a FHS
|
|
# env in which it can run. On first use, the user will need to install conda to
|
|
# the installPath using the installer:
|
|
# $ nix-env -iA conda
|
|
# $ conda-shell
|
|
# $ conda-install
|
|
#
|
|
# Under normal usage, simply call `conda-shell` to activate the FHS env,
|
|
# and then use conda commands as normal:
|
|
# $ conda-shell
|
|
# $ conda install spyder
