print function not working

[treasersimplifies]

testing codes:

#include <eosiolib/eosio.hpp>
#include <eosiolib/print.hpp>
using namespace eosio;
class hello : public contract {
  public:
      using contract::contract;

      [[eosio::action]]
      void hi( account_name user, account_name words) {
        require_auth( user );
        print( "Hello, myfirst smc, ", name{user},", ", name{words});
      }
};
EOSIO_ABI( hello, (hi))

when I run the following cmd in my shell:

treaser$ cleos set contract testhero /DIR/EOScontracts/hello -p testhero

no output from print function.I don't know where is wrong.I have tried with many smart contracts, and print function is not working in all of them. And the above test hello-world program used to have print output initially when I use EOS development environment not the current production environment.

Have you run nodeos with --contracts-console option? (or you can add contracts-console = true in your config.ini for nodeos)

How silly I am ! It works, thank you !

Wait... a new problem appear: when I use print("\n"); the code behind it didn't work any more.

Look at #5647

v1.7.4 has add contracts-console = true in config.ini, but still do not print log in nodeos
