在ubuntu上，发现另外一种装法，更加简单快捷
- conda create vnpy3 python=3.10
- conda activate vnpy3
- pip install vnpy vnpy_ctastrategy vnpy_ctabacktester vnpy_spreadtrading vnpy_optionmaster vnpy_portfoliostrategy vnpy_algotrading vnpy_scripttrader vnpy_paperaccount vnpy_chartwizard vnpy_portfoliomanager vnpy_rpcservice vnpy_datamanager vnpy_datarecorder vnpy_excelrtd vnpy_riskmanager vnpy_webtrader vnpy_rest vnpy_websocket vnpy_sqlite vnpy_mysql vnpy_tushare vnpy_ctp
这样就完成安装了。
下面开始测试， 参考 https://gitee.com/vnpy
新建一个工作目录，在里面建立文件 run.py， 里面的内容如下 ：
from vnpy.event import EventEngine
from vnpy.trader.engine import MainEngine
from vnpy.trader.ui import MainWindow, create_qapp
from vnpy_ctp import CtpGateway
from vnpy_ctastrategy import CtaStrategyApp
from vnpy_ctabacktester import CtaBacktesterApp
def main():
"""Start VeighNa Trader"""
qapp = create_qapp()
event_engine = EventEngine()
main_engine = MainEngine(event_engine)
main_engine.add_gateway(CtpGateway)
main_engine.add_app(CtaStrategyApp)
main_engine.add_app(CtaBacktesterApp)
main_window = MainWindow(main_engine, event_engine)
main_window.showMaximized()
qapp.exec()
if name == "main":
main()
在终端里面行下列命令启动VeighNa Trader：
python run.py
原来 vnpy的界面可以根据自己的需要裁剪， 不错。
本人也是如此安装，系统ubuntu20.04，conda 4.13.0。但运行examples/veighna_trader/run.py
报如下错误。
找不到数据服务驱动vnpy_，使用默认的RQData数据服务

有什么解决办法吗？
已解决：将vnpy_rqdata退后一个版本。查了下论坛感觉遇到出错，大多数可以将使用的包退后到某个版本能解决问题。
希望给大家带来帮助
