using npm imports

I was really excited to read the following blog post...
https://deno.com/blog/frameworks-with-npm

but I get the following error when I try to load my edge function:
error: Following npm specifiers were requested: "geo-from-ip"; but --no-npm is specified.


is there a better way to load this and future dependencies?
