  ImportError: No module named vnctpmd
  

  vnctpmd模块是VnPy包的CTP代理的API接口 . 对于其他所有API接口，您需要先构建它，然后导入它 .

  在您的情况下，您可能在安装VnPy时出现提示 didn't build the CTP interface ，所以现在run.py无法导入模块 .

  Do you need 'CTP' interface? No
  

  Solution A: I don't need CTP interface

  如果您不需要CTP接口，可以打开run.py评论相对于CTP的部分（以及相对于您未构建的所有其他接口）

  # /examples/VnTrader/run.py script
  # this version runs with only the IB interface built
  
  # encoding: UTF-8
  
  # 重载sys模块，设置默认字符串编码方式为utf8
  try:
      reload         # Python 2
  except NameError:  # Python 3
      from importlib import reload
  
  import sys
  reload(sys)
  
  try:
      sys.setdefaultencoding('utf8')
  except AttributeError:
      pass

  # 加载底层接口
  from vnpy.trader.gateway import ibGateway
  
  # ### here comment the interfaces you don't need

  # 加载上层应用
  from vnpy.trader.app import (riskManager, ctaStrategy,

      # 创建主引擎
      me = MainEngine(ee)
  
      # 添加交易接口
      # me.addGateway(ctpGateway)
      me.addGateway(ibGateway)
  
      if system == 'Windows':
          me.addGateway(femasGateway)
          me.addGateway(xspeedGateway)
          me.addGateway(secGateway)

      pass
  
      # 添加上层应用
      me.addApp(riskManager)
      me.addApp(ctaStrategy)
      me.addApp(spreadTrading)
      me.addApp(algoTrading)
  
      # 创建主窗口
      mw = MainWindow(me, ee)
      mw.showMaximized()
  
      # 在主线程中启动Qt事件循环
      sys.exit(qApp.exec_())
  
  
  if __name__ == '__main__':
      main()
  

  Solution B: I need CTP interface

  如果您需要CTP，可以使用该命令重新安装vnpy

  bash install.sh
  

  当提示'你需要CTP'时回答是
