Question

我正在尝试安装upstox，这是一个用于连接市场数据的Python API。我无法在Python3.5上安装它。

我的配置是 Python 3.5.3 (v3.5.3:1880cb95a742, Jan 16 2017, 15:51:26) [MSC v.1900 32 bit (Intel)] on win32。我一直得到的错误是：

Answer 3

import enum import Enum
import enum import IntNum

from enum import Enum
from enum import IntEnum

class Shape (IntEnum):
    CIRCLE = 1
    SQUARE = 2


class Color (Enum):
    RED = 1
    GREEN = 2


print(Shape.CIRCLE == Color.RED)
print (Shape.CIRCLE == 1)

Answer 4

在安装所需的软件包之前，您是否安装了enum？看起来它希望你先安装它。

在CMD中运行此命令以安装enum，然后尝试安装所需的软件包：

pip install enum

ImportError：无法导入名称'IntEnum'
