Getting error "AttributeError: module "ibapi.contract" has no attribute "UnderComp"

Question

我已经尝试了一段时间让下面的代码工作，但我一直收到这个错误信息。我做错了什么？

from ib_insync import IB

ib = IB()
ib.connect("127.0.0.1",7497,clientId=1)

stock = Stock("AMD","SMART","USD")
bars = ib.reqHistoricalData(
    stock,
    endDateTime="",
    durationStr="30 D",
    barSizeSetting="1 hour",
    whatToShow="MIDPOINT",
    useRTH="True"
    )

    
print(bars)

错误信息：

看来，您使用的是旧的 ib-insync 包（0.9.11 版）。尝试安装对我有用的最新版本 ib-insync 0.9.64。另外，关注群以获取更多信息：https://groups.io/g/insync
