# Install optional packages (eg extra Jupyter kernels) on top of conda-installed SageMath

Suppose one has installed SageMath using the conda package.

How does one then install optional packages?
It seems `sage -i`

is not active there.

For example, what would be the replacement for

```
$ sage -i gap_jupyter # install Jupyter kernel for GAP 4.8
$ sage -i pari_jupyter # install Jupyter kernel for PARI/GP
$ sage -i r_jupyter # install Jupyter kernel for R
$ sage -i singular_jupyter # install Jupyter kernel for Singular
```

if one is using a conda-installed Jupyter and SageMath?
