Jenkins执行pytest测试时出现ModuleNotFoundError: 'chromedriver_py'

错误信息

C:\Users\user\PycharmProjects\Project1>pytest -s -v test_cases\ 
ImportError while loading conftest 'C:\Users\user\PycharmProjects\Project1\test_cases\conftest.py'.
test_cases\conftest.py:4: in <module>
    from chromedriver_py import binary_path
E   ModuleNotFoundError: No module named 'chromedriver_py'

注意：本地运行所有测试均正常。

conftest.py内容

import pytest
from selenium import webdriver
from selenium.webdriver.chrome.service import Service
from chromedriver_py import binary_path

service_object = Service(executable_path=binary_path)
options = webdriver.ChromeOptions()
options.add_experimental_option("detach", True)

@pytest.fixture(scope='module')
def driver():
    driver = webdriver.Chrome(service=service_object, 
    options=options)
    driver.maximize_window()
    return driver

Jenkins流水线当前命令

pipenv shell
pytest -s -v test_cases\

解决方法

确保项目依赖文件包含chromedriver_py：
本地执行pipenv install chromedriver_py，将更新后的Pipfile和Pipfile.lock提交到代码仓库。
修改Jenkins流水线命令，先安装依赖再执行测试：
```
pipenv install
pipenv run pytest -s -v test_cases\
```
用pipenv run直接在虚拟环境中执行命令，避免pipenv shell的环境激活问题。
确认Jenkins任务的工作目录为项目根目录，保证命令执行路径正确。
