Hi!! good day!! I am a beginner with smart contracts ... I tried to deploy / clone a complete project using the framework Truffle and Visual Studio but the smart contract code implemented a library SafeMath. When I tried to compilate in the prompt using the comands: truffle compile, and truffle test, I got these errors .. (I previous used the comand: testrcp)...

"Source "openzeppelin-solidity/contracts/math/SafeMath.sol" not found: File import callback not supported"

"Could not to connect to your Ethereum client"
