关于python pytest中的hook函数，无法读取出数据问题

###代码部分

import os
from typing import Union

BASE_DIR: Union[bytes, str] = os.path.dirname(os.path.abspath(__file__))

# 添加一个命令行参数
# 你可以在Terminal命令行中输入pyetst --help |group ZR可查看
def pytest_addoption(parser):
    mygroup = parser.getgroup('ZR')
    mygroup.addoption('--test',  # 注册一个命令选项
                      default='test',  # 参数默认值
                      dest='env',
                      help='set your run env'  # 帮助提示   参数的详细描述
                      )


@pytest.fixture(scope="session")
def cmdoption(request):
    env = request.config.getoption('--env', default='test')
    if env == 'dev' or env == 'DEV':
        datapath = BASE_DIR + r"/TestData/datas/dev/datas.yaml"
        # print(my_file_content(datapath))

    elif env == 'test' or env == 'TEST':
        datapath = BASE_DIR + r"/TestData/datas/test/datas.yaml"
        # print(my_file_content(datapath))

    elif env == 'pre' or env == 'PRE':
        datapath = BASE_DIR + r"/TestData/datas/pre/datas.yaml"
        # print(my_file_content(datapath))

    else:
        raise EnvironmentError(f'Please set up your environment ! Current Context:{env}')
    with open(datapath) as f:
        datas = yaml.safe_load(f)
    return env, datas

问题

报错信息

在Terminal命令行中输入pytest --env DEV get_api_url.py::get_app_url -vs 进行环境切换报错
UnicodeDecodeError: ‘gbk’ codec can’t decode byte 0x80 in position 156: illegal multibyte sequence

我通过python的chardet模块写后执行还是无法读取

import chardet


def my_file_content(file_path):
    """
    使用了 `chardet` 模块来自动检测文件的编码方式，然后使用检测到的编码方式对文件进行解码。
    :param file_path: 你的文件路径
    :return:
    """
    with open(file_path, 'rb') as f:
        data = f.read()
        file_encoding = chardet.detect(data)['encoding']
        file_content = data.decode(file_encoding)
    return file_content
‘’‘’
报错信息
Failed: Fixture "cmdoption" called directly. Fixtures are not meant to be called directly,

### 环境
yaml文件
‘’‘yaml
