npm update fails with cryptonote

I’m installing the electroneum pool git. I ran npm update and I keep getting the same error, I’ve tried changing node version but that doesn’t make any difference.

Here is the error

root@ubuntu:~/pool# npm update

> bignum@0.12.5 install /root/pool/node_modules/bignum
> node-pre-gyp install --fallback-to-build

[bignum] Success: "/root/pool/node_modules/bignum/binding/bignum.node" is installed via remote

> cryptonote-util@0.0.3 install /root/pool/node_modules/cryptonote-util
> node-gyp rebuild
