Can't compile the equihash verifier in aion_solo_pool

node-gyp configure fails with the following error message:

As far as I can see I have all the correct requirements and versions installed.

Could you try navigating to the aion_solo_pool folder and running npm install?

Seems like node is missing that "nan" package on some node installs.

[JimVanEeden]

Great, that works. You should probably change the order of step 3 and step 4 in the docs so other people don't get the same problem.

I'd like to add that I fixed this error by installing the legacy version of nodejs, whereas installing via npm from the root directory threw a bundledDependency error.
