After I copied the secp256k1 from the deps fold to node_modules fold and run "node index.js", I saw this error message "secp256k1.createPublicKey is not a function", how to solve this problem?
Is your issue about cryptocoinjs/secp256k1-node?
What purpose of coping some deps to node_modules? Please use yarn/npm/etc.
What in index.js which you run with node?
Without details such issues can not be solved.
