好久之前测试都没问题，最近折腾vnpy,发现连不上了

（已经解决）

https://zhuanlan.zhihu.com/p/103834397 按照这个文章的说法，在在/vnpy/trader目录下建立tuquery.py文件下建立了文件，然后同时在/vnpy/app/cta_backtester目录下找到engine.py，导入包

from vnpy.trader.tuquery import tusharedata
在run_downloading函数下找到“try:”，if……else:这里将原来的

data = rqdata_client.query_history(req)

发现报错之后，我把原文件换了回去，但是还是报错。

Traceback (most recent call last):

重启了还是不行，难不成要重装？
