[Nix-dev] nixops "No such file or directory" after creation

[Richard Wallace]

Aha! Because I started with `nix-shell --pure -p nixops` none of the nix
commands were in my $PATH and I didn't even realize it.  That fixed it.

I'd like to avoid needing to use nix-shell to use nixops, but when I try to
use nixops from my regular shell I get

$ nixops list
Traceback (most recent call last):
  File

ImportError:

undefined symbol: PyUnicodeUCS2_AsEncodedString

If someone could tell me how to fix that I would be extremely happy. :)

Thanks,
Rich
