selector 'nix-repl' matches no derivations

Question

I have nix installed

➜  which nix
/Users/rabraham/.nix-profile/bin/nix
➜ nix --version
nix (Nix) 2.1.3

Nix Channel is:

➜ cat ~/.nix-channels
https://nixos.org/channels/nixos-18.09 nixpkgs

But I can't install nix-repl

➜ nix-env -i nix-repl
error: selector 'nix-repl' matches no derivations

Answer 1

The documentation is outdated. I think nix repl already works without a separate install from Nix 2.0 onwards.
