Errors on Install (Its falling back to the pure JS implementation of keccak and secp256k1)

[HM999]

Brand new computer, installing web3, got some errors (failures)...

Is my installation usable?

npm i web3

The module appears to have installed, but those errors look pretty bad. Is my installation ok to use?

Thanks for opening this issue! Yes, your installation is safe to use. The ethereumjs-util package does still have a dependency on node-gyp which occurs this error above. But as you can see is it falling back to a pure JavaScript implementation for keccak: Keccak bindings compilation fail. Pure JS implementation will be used.. We will improve this asap.

It is now possible to install web3.js on the latest version of nodejs as expected. Thanks to @evertonfraga for publishing the required fixes in the dependencies we use.
