We use Nexus as our internal repo.

What configuration modifications do we need to make to route pip and cran calls inside JupyterHub to our internal Nexus repos.

Hi. Do you mean you want to redirect calls made from a shell in a singleuser server such as JupyterLab to PyPI and CRAN? In most cases each user will have their own shell environment including their own home directory. I haven’t used Nexus, but assuming it provides the same API as PyPI/CRAN you can add whatever config files you’d normally use outside of JupyterHub, e.g.

- [Configuration - pip documentation v23.1.2](https://pip.pypa.io/en/stable/topics/configuration/)
- [Permanently Setting the CRAN repository | R-bloggers](https://www.r-bloggers.com/2011/11/permanently-setting-the-cran-repository/)
