It just doesnt work. I have spent hours looking on the internet and no solution seems to work for me.

root@ewerton-azevedo-blockchainlab-5299615:/home/ubuntu/workspace# npm 
install ethereumjs-testrpc web3

> uglifyjs-webpack-plugin@0.4.6 postinstall 
/home/ubuntu/workspace/node_modules/uglifyjs-webpack-plugin
> node lib/post_install.js

It works when I try

`npm install web3@0.19`
