Question

我试图了解RxPy的工作原理，但出现此错误

类型对象“ ObservableBase”没有属性“创建”

我正在使用python 3.6，我的代码是

from rx import Observable

stocks = [
  {'TCKR': 'APPL', 'PRICE': 200},
  {'TCKR': 'GOOG', 'PRICE': 90},
  {'TCKR': 'TSLA', 'PRICE': 120},
  {'TCKR': 'MSFT', 'PRICE': 150},
  {'TCKR': 'INTL', 'PRICE': 70},
  {'TCKR': 'ELLT', 'PRICE': 0}
]

def buy_stock_events(observer):
   for stock in stocks:
      if (stock['PRICE'] > 100):
        observer.on_next(stock['TCKR'])
   elif (stock['PRICE'] <= 0):
        observer.on_error(stock['TCKR'])
   observer.on_completed()

source = Observable.create(buy_stock_events)

source.subscribe(on_next=lambda value: print("Received Instruction to buy {0}".format(value)),
            on_completed=lambda: print("Completed trades"),
            on_error=lambda e: print(e))

Answer 1

我找到了解决方法，

更改

中的代码

S (Add x' x)

到

from rx import Observable
source = Observable.create(buy_stock_events)

它正在工作

Answer 2

他们已经更新了RxPy模块。安装1.6.1，即可解决问题。谢谢
