Ethereum 如何使用浓度为6.0的块菌？

在阅读官方的块菌文档时，我注意到块菌不支持Solidity 6.0

pragma solidity >=0.4.21 <0.6.0;

---

pragma solidity>=0.4.21是，此迁移适用

pragma solidity >=0.4.21 <0.7.0;

contract Migrations {
  address public owner;
  uint public last_completed_migration;

  constructor() public {
    owner = msg.sender;
  }

  modifier restricted() {
    if (msg.sender == owner) _;
  }

  function setCompleted(uint completed) public restricted {
    last_completed_migration = completed;
  }
}

还需要将Truffle重新安装到最新版本
