一直以来用Anaconda python(3.5以上版本)开发些爬虫及自动化测试的应用。由于一直用pip xxx install 联网安装一些第三方扩展包，以为开源时代必须这么装了。 因为内联网无法用pip 下载安装，逼着自己去找离线安装的方法， selenium官网写到： Installing： If you have pip on your system, you can simply install or upgrade the Python bindings: pip install -U selenium Alternately, you can download the source distribution from PyPI (e.g. selenium-3.141.0.tar.gz), unarchive it, and run: python setup.py install Note: You may want to consider using virtualenv to create isolated Python environments. 实际就是 下载selenium-3.141.0.tar.gz，解包到任意目录，在Anaconda Prompt 下 cd selenium 解包路径 python setup.py install
