python-3.x – 如何使用python3.7处理ib_insync中的异步错误?

对不起,我可能会问一个愚蠢的问题,但我只是
python和algotrading的初学者.

我现在使用python 3.7和ibapi与ib_insync来尝试连接TWS.但是,因为python 3.7使用async作为关键字,所以当我尝试使用ib_insync进行编码时:

from ib_insync import *

ib = IB()
ib.connect('127.0.0.1', 7496, clientId=1)

contract = Forex('EURUSD')
bars = ib.reqHistoricalData(contract, endDateTime='', durationStr='30 D', barSizeSetting='1 hour', whatToShow='MIDPOINT', useRTH=True)

df = util.df(bars)
print(df['date', 'open', 'high', 'low', 'close'])

它最终是这样的:

File "C:/Users/leung/Documents/MONEY/Algotrade/venv/test1.py", line 1, in <module>
    from ib_insync import *
  File "C:\Users\leung\AppData\Local\Programs\Python\Python37-32\lib\site-packages\ib_insync\__init__.py", line 24, in <module>
    from .ib import *
  File "C:\Users\leung\AppData\Local\Programs\Python\Python37-32\lib\site-packages\ib_insync\ib.py", line 11, in <module>
    from ib_insync.client import Client

    self.async = False
             ^

我知道我需要将名称async更改为其他名称.我试图在ibapi中修改文件client.py,但它似乎根本不起作用.为了让它工作,我应该改变哪部分代码?

最佳答案 我在API 973.07中偶然发现了同样的错误.在我的情况下,我使用MacOS,因此文件路径看起来与Windows环境不同,但想法是一样的.为了解决这个问题,我刚刚将文件IBJts / source / pythonclient / build / lib / ibapi / client.py中的第60行注释掉,如下所示:

#        self.async = False

不确定它是否会影响其他任何东西,但至少我可以通过以下方式编译并正确安装库:

python3 setup.py install

PS在123行os中同一个文件有评论

#TODO: support async mode

希望我的改变不会破坏任何东西
