网上找到很多方法添加路径
from selenium import webdriver browser = webdriver.Firefox("C:\Program Files (x86)\Mozilla Firefox\firefox.exe")
添加PATH环境变量,还是报错,
后来在stackoverflow找到答案

Firefox和Chrome，需要下载geckodriver / chromedriver。这些驱动程序是您安装的浏览器与selenium之间进行通信所必需的。所以你需要：
firefox驱动下载地址: https://github.com/mozilla/geckodriver/releases
chrome驱动下载地址: https://sites.google.com/a/chromium.org/chromedriver/downloads
1. 安装python（pip install selenium）selenium
2. 下载你使用的浏览器的驱动程序（chromedriver，geckodriver，operadriver等）
将所下载的驱动geckodriver.exe文件路径添加到代码
谷歌 : driver = webdriver.Chrome(executable_path=‘/path/to/chromedriver.exe‘)
火狐: driver = webdriver.Firefox(executable_path=‘/opt/geckoDriver/geckodriver.exe‘)
完整代码:
from selenium import webdriver #browser = webdriver.Firefox() browser = webdriver.Firefox(executable_path=r‘C:\Users\Administrator\Desktop\bs\geckodriver.exe‘) browser.get(‘http://www.baidu.com/‘)
# -*- coding: utf-8 -*- from selenium import webdriver from selenium.webdriver.firefox.firefox_binary import FirefoxBinary gecko = os.path.normpath(os.path.join(os.path.dirname(__file__), ‘geckodriver‘)) binary = FirefoxBinary(r‘C:\Program Files (x86)\Mozilla Firefox\firefox.exe‘) browser = webdriver.Firefox(firefox_binary=binary,executable_path=gecko+‘.exe‘) browser.get(‘http:///www.google.com‘) browser.close()
