Python 3.x 机器人框架中多基地存在实例布局冲突

我正在创建一个新的测试框架，我开始在

*.py

文件中实现我自己的函数，但当我尝试运行测试时，我得到了以下堆栈：

(venv) PLAMWS0024:OAT user$ robot -v CONFIG_FILE:"/variables-config.robot" ./catalog/tests/test1.robot
Traceback (most recent call last):
  File "/Users/user/PycharmProjects/OAT/venv/bin/robot", line 5, in <module>

    class Error(Statement, Exception):
TypeError: multiple bases have instance lay-out conflict

和呼叫VAR：

from robot.libraries.BuiltIn import _Variables
from robot.parsing.model.statements import Error
Vars = _Variables()


def get_value_from_clipboard(name):
    """
    Returns value saved inside variables passed in Robot Framework
    :param name: name of the variable, needs to have ${} part
            as example: ${var} passed in config file
    :return: value itself, passed as string
    """
    try:
        return Vars.get_variable_value(name)
    except Error as e:
        raise Error('Missing parameter in the clipboard, stack:' + str(e))

什么固定问题：

• 从

  requirements.txt

  文件中卸载所有需求并逐个安装

我尝试了其他步骤：

• 逐个注释掉所有文件并仅运行

  robot

  命令-失败，出现相同错误
• 已按此处所述清理

  vnenv

  ：（失败）
• 检查是否有任何变量具有与

  python3.8/site packages/robot/parsing/model/statements.py中描述的相同的命名

因此，在安装PyCharm IDE的需求时似乎存在一些冲突

from datetime import datetime
from robot.api import logger
from robot.libraries.BuiltIn import _Variables
from robot.parsing.model.statements import Error
import json
import datetime
from catalog.resources.utils.clipboardContext import get_value_from_clipboard

Vars = _Variables()


def foo_bar(params):
    # Get all variables
    country = get_value_from_clipboard('${COUNTRY}')
    address = get_value_from_clipboard('${ADDRESS}')
    city = get_value_from_clipboard('${CITY}')
    postcode = get_value_from_clipboard('${POSTALCODE}')

from robot.libraries.BuiltIn import _Variables
from robot.parsing.model.statements import Error
Vars = _Variables()


def get_value_from_clipboard(name):
    """
    Returns value saved inside variables passed in Robot Framework
    :param name: name of the variable, needs to have ${} part
            as example: ${var} passed in config file
    :return: value itself, passed as string
    """
    try:
        return Vars.get_variable_value(name)
    except Error as e:
        raise Error('Missing parameter in the clipboard, stack:' + str(e))
