报错信息提示WTMSIG_BLOCK_SIGNATURES
查看合约更新日志
https://github.com/EOSIO/eosio.contracts/releases/tag/v1.9.1

The eosio.system and eosio.bios contracts contained in this release can only be deployed on an EOSIO blockchain after the activation of the WTMSIG_BLOCK_SIGNATURES consensus protocol upgrade.

只有开启WTMSIG_BLOCK_SIGNATURES共识才能使用此合约。
根据查看 https://github.com/EOSIO/eos/pull/7404

开启WTMSIG_BLOCK_SIGNATURES共识

目前开启WTMSIG_BLOCK_SIGNATURES共识，需要系统账户先部署eosio.boot，并且此合约在单独的合约分支（吐槽下EOSIO代码版本管理...）
先获取下add-boot-contract分支合约

git clone --branch add-boot-contract https://github.com/EOSIO/eosio.contracts.git
./[path]/eosio.contracts/build.sh

和之前部署一样先激活PREACTIVATE_FEATURE

curl -X POST http://127.0.0.1:8888/v1/producer/schedule_protocol_feature_activations -d '{"protocol_features_to_activate": ["0ec7e080177b2c02b278d5088611686b49d739925a92d9bfcacd7fc6b74053bd"]}' | jq

然后部署下eosio.boot合约

cleos set contract eosio [path]/eosio.contracts/build/contracts/eosio.boot -p eosio@active

激活WTMSIG_BLOCK_SIGNATURES协议

cleos -u http://127.0.0.1:8888 push transaction '{"delay_sec":0,"max_cpu_usage_ms":0,"actions":[{"account":"eosio","name":"activate","data":{"feature_digest":"299dcb6af692324b899b39f16d5a530a33062804e41f09dc97e9f156b4476707"},"authorization":[{"actor":"eosio","permission":"active"}]}]}'

最后查询下PREACTIVATE_FEATURE和WTMSIG_BLOCK_SIGNATURES是否已成功激活

curl -X POST http://127.0.0.1:8888/v1/chain/get_activated_protocol_features -d '{}' | jq

{
  "activated_protocol_features": [
    {
      "feature_digest": "0ec7e080177b2c02b278d5088611686b49d739925a92d9bfcacd7fc6b74053bd",
      "activation_ordinal": 0,
      "activation_block_num": 1176,
      "description_digest": "64fe7df32e9b86be2b296b3f81dfd527f84e82b98e363bc97e40bc7a83733310",
      "dependencies": [],
      "protocol_feature_type": "builtin",
      "specification": [
        {
          "name": "builtin_feature_codename",
          "value": "PREACTIVATE_FEATURE"
        }
      ]
    },
    {
      "feature_digest": "299dcb6af692324b899b39f16d5a530a33062804e41f09dc97e9f156b4476707",
      "activation_ordinal": 1,
      "activation_block_num": 12770,
      "description_digest": "ab76031cad7a457f4fd5f5fca97a3f03b8a635278e0416f77dcc91eb99a48e10",
      "dependencies": [],
      "protocol_feature_type": "builtin",
      "specification": [
        {
          "name": "builtin_feature_codename",
          "value": "WTMSIG_BLOCK_SIGNATURES"
        }
      ]
    }
  ]
}

然后继续之前的步骤，继续部署eosio.bios合约，以及后面的步骤

cleos set contract eosio contracts/eosio.bios
