“ModuleNotFoundError: No module named ‘selenium‘”报错如何解决

接上节：测试平台开发之测试框架改造并发执行及结果隔离(1)
上节博客的末尾提到：在命令窗口执行python main.py
可是执行的时候遇到了如下报错：

那么针对这个报错，要如何解决呢？

1. 模块导入错误

报错信息显示 selenium 模块未找到。你需要确保 selenium 安装在你的虚拟环境中。你可以通过以下步骤来解决：

激活你的虚拟环境（假设你的虚拟环境路径是 D:\cekai\xuexi\Tesla.venv）：

D:\cekai\xuexi\Tesla\.venv\Scripts\activate

2、安装 selenium 模块：

pip install selenium

如果继续遇到报错：

两种方式解决：

1、使用国内的 PyPI 镜像源

pip install selenium -i https://pypi.tuna.tsinghua.edu.cn/simple

2、设置超时

pip install selenium --timeout=120

3、验证 selenium 是否安装成功：

pip list

4、未知的配置选项警告

在 pytest.ini 文件中有两个未知的配置选项：result_log_verbose 和 xlsx_meta_column_name。这些选项不是 pytest 的标准配置选项，可能是由某些插件或自定义逻辑添加的。你可以通过以下步骤来解决：
1、检查 pytest.ini 文件：
打开 pytest.ini 文件并确认是否有以下内容：

5、allure 命令找不到

安装 allure 命令行工具：
你可以从 Allure2 官方 GitHub 下载适用于你系统的版本。
下载并解压后，将 bin 目录添加到系统的 PATH 环境变量中。

6、再次执行用例

 python main.py

可以看到用例运行成功
