Installation error using Nix

[joshiqc]

I have never used Nix before and I'm getting the following error:

nix-shell -p python37Packages.scikits-odes -p python37Packages.numpy --run "python3" error: … while calling the 'derivationStrict' builtin

     at /builtin/derivation.nix:9:12: (source not available)

         |                                                  

How do I fix this?

I think you would need to ask on the various nix support forums, the nix support was done by nix users.
