var query = wx.createSelectorQuery();
      var test = query.select('test')
      console.log(test)
      wx.createMediaRecorder(qian, {
        duration: 1000
      })

真机调试，报错

appServiceSDKScriptError
Cannot read property 'MediaToolKit' of undefined; at wx.createMediaRecorder
TypeError: Cannot read property 'MediaToolKit' of undefined

已经在开发工具中将基础库调至2.11.0
