-Currently there is an upstream bug in the nixops package which results in an error during `nixops create`. That is why we have to build nixops from source until a binary with the bug-fix is released.

Alternatively you can change your path, i.e. `export PATH=/nix/store/wa6nk3aqxjb2mgl9pkwrnawqnh9z1b9d-nixops-1.6.1pre0_abcdef/bin/:$PATH` so you can just type nixops.
