Wasmer add is quiet

[syrusakbary]

Executing: wasmer add dynamite-bud/ayush --npm outputs nothing to stdout, which makes it hard to know if it has succeeded or what was the npm command that ran under the hood.

What I would expect is something along this lines:

$ wasmer add dynamite-bud/ayush --npm
Fetching npm package for dynamite-bud/ayush
Running: npm install https://abc.tar.gz
-> STDOUT from npm in realtime
