最近在学习MetaGPT：https://github.com/geekan/MetaGPT

在多智能体入门（多智能体入门 | MetaGPT）以及辩论：智能体对抗（辩论：智能体对抗 | MetaGPT）中，代码均会报错：

据官方修复（https://github.com/geekan/MetaGPT/pull/1759），需要引入Teamleader:

即添加：

from metagpt.roles.di.team_leader import TeamLeader

以及

team.hire([TeamLeader(), ......])

from metagpt.roles.di.team_leader import TeamLeader

......

......

async def main(
    idea: str = "write a function that calculates the product of a list",
    investment: float = 0.1,
    n_round: int = 3,
    add_human: bool = False,
):
    logger.info(idea)

    team = Team()
    team.hire(
        [
            TeamLeader(),
            SimpleCoder(),
            SimpleTester(),
            SimpleReviewer(is_human=True),
        ]
    )

    team.invest(investment=investment)
    team.run_project(idea)
    await team.run(n_round=n_round)
