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功能，但是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>
    from robot.run import run_cli

    from robot.run import RobotFramework

    from .statements import Statement
  File "/Users/user/PycharmProjects/OAT/venv/lib/python3.8/site-packages/robot/parsing/model/statements.py", line 453, in <module>
    class Error(Statement, Exception):
TypeError: multiple bases have instance lay-out conflict

我怀疑这是因为在我的一个文件中，我试图从内置功能的 Robot Framework 中获取变量。我想这是因为我正在尝试使用受保护的方法，但我不确定。

我发现了问题TypeError: multiple bases have instance lay-out conflict，它表明命名约定可能不匹配（或者我错了吗？），但我的项目有点小，所以唯一的选择是机器人看不到该功能自己。

我会错过什么？

一些代码：

测试自己：

*** Settings ***
Documentation     TO BE CHANGED
...               SET IT TO CORRECT DESCRIPTION
Library           ${EXECDIR}/file.py
Library           String

*** Test Cases ***
User can do stuff
    foo bar

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}')

并调用 Vars：

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))

标签： python-3.x robotframework

【解决方案1】：

解决了什么问题：

从requirements.txt 文件中卸载所有要求，并一一安装。

我尝试的其他步骤：

逐一注释掉所有文件并仅运行robot 命令 - 失败，出现相同错误
已清理 vnenv，如下所述：How to reset virtualenv and pip?（失败）
检查是否有任何变量具有与python3.8/site-packages/robot/parsing/model/statements.py 中所述相同的命名 - 无

所以看起来 PyCharm IDE 在安装要求方面存在一些冲突
