Linux环境Python2.7.14+执行python setup.py遇selenium安装错误求解决

That error pops up because Selenium stopped supporting Python 2.7 starting with version 4.x. Since Python 2.7 reached its end-of-life in 2020, almost all modern packages (including Selenium) no longer maintain compatibility with it. Here are your two main options to resolve this:

Solution 1: Upgrade to Python 3 (Highly Recommended) #

Sticking with Python 2.7 means missing out on security patches, new features, and support for most modern libraries. Upgrading to Python 3 is the best long-term fix. Here's how to do it on Linux:

• Install Python 3 and its package manager using your distribution's tools:
  • For Debian/Ubuntu-based systems:

    sudo apt update && sudo apt install python3 python3-pip
    

  • For RHEL/CentOS/Fedora:

    sudo dnf install python3 python3-pip
    

• Once installed, use pip3 to install the latest Selenium:

  pip3 install selenium
  

Solution 2: Install an Older Selenium Version (If You Must Stay on Python 2.7) #

If upgrading isn't an option right now, you can install the last Selenium version that supports Python 2.7: 3.141.0. Here's how:

• First, make sure you're using Python 2's pip (often called pip2):
  • Check if pip2 is available:

    pip2 --version
    

  • If not, install it:
    • Debian/Ubuntu: sudo apt install python-pip
    • RHEL/CentOS/Fedora: sudo dnf install python2-pip
• Install the compatible Selenium version:

  pip2 install selenium==3.141.0
  

Keep in mind that Selenium 3.x won't get any security updates or new features anymore, so upgrading to Python 3 should be your priority whenever possible.
