Windows 10: cant run start.js cause bignum module is missing although (I think) I installed it.

[papajo-r]

so if I try to run node.js I get
node:internal/modules/cjs/loader:930
throw err;
^

Error: Cannot find module 'bignum'

  }

I installed openssl with chocolate and also I installed bignum with git clone git://github.com/justmoon/node-bignum.git
but I get the same error.

Copy url of ErgoStratum to package.json and replace. Then npm install it will install packages ;) you didnt need install.
