Selenium常见问题
2024.12.04
在Pycharm中运行Selenium+Pytest测试程序时不能启动火狐浏览器，有时报空套件错误。可能是软件版本引起的，也可能是与其他软件冲突导致的。出现问题所用的软件版本如下：
Python 3.12.3，Selenium 4.27.0，Pytest 8.3.3
在Pycharm中可以删除虚拟环境，重新创建虚拟环境。在Pycharm终端安装Selenium 4.27.1，Pytest 8.3.4。问题消失。
用如下的命令安装指定版本的软件：
pip install selenium==4.27.1
在Windows命令窗口安装的软件属于全局环境，在Pycharm中创建的虚拟环境属于项目的局部环境，在Pycharm终端安装的软件属于虚拟环境。创建虚拟环境时可以选择继承全局环境。
