So, I keep getting an error while trying to install this stratum server code on Ubuntu.  I've tried several systems, and updating redis and python as described in the readme, but the error never changes or improves. 

I get the following a little ways through running "npm update"....

npm http 304 https://registry.npmjs.org/bignum/0.7.0
npm http 404 https://registry.npmjs.org/multi-hashing/0.0.9

Can anyone help?
