environment construction under WINDOW10

1. Install Python

https://www.python.org/downloads/Download the latest version of Python under this URL, click Install, select Add Python path to PATH environment variable during installation

2. Installing Setuptools and Pip

Setuptools makes it easier to create and publish Python packages, especially if you have dependencies on other packages

Pip is a tool for installing and managing Python packages, installation relies on Setuptools, and using the PIP command to better install Python third-party libraries

3. Installing Selenium

Enter PIP install selenium on the cmd command line to install Selenuim

4. I'm using pycharm for encoding.

Some of the pits encountered

1. Run a small example with Webdriver to meet the pit below

Selenium is a big change from the previous one, one of which is that Webdriver is separated from the browser and needs to be installed separately

Download : https://github.com/mozilla/geckodriver/releases

Unzip: Customize an address, remember that address

Environment variables: Add decompressed addresses to environment variables

2. Baidu a lot, finally thought to solve this problem, but found another problem, session creation exception

Tears ran, find a lot of information, just know is to follow the current download the highest version of the Geckodriver, nonsense not to say, download the previous version, find a 15.0 version of the reinstallation

At this point, the program can run.
