1. 安装 selenium
pip install selenium =3.11.0 # 安装指定版本
pip install selenium -U # 安装最新版本
pip show selenium # 查看当前版本
pip uninstall selenium # 卸载
报错解决1: 带上代理
pip install selenium -i http://mirrors.aliyun.com/pypi/simple/
报错解决2: 添加信任
pip3 install selenium==3.11.0 -i http://mirrors.aliyun.com/pypi/simple/ --trusted-host mirrors.aliyun.com
2. 第一个selenium 测试脚本
pycharm 设置 anaconda 的python 解释器
2.1安装谷歌浏览器驱动
2.1.1查找谷歌浏览器版本
2.1.2驱动下载
驱动下载; 【笔记】chromedriver下载与安装方法_chrome驱动_逸峰轻云的博客-CSDN博客
淘宝镜像:https://registry.npmmirror.com/binary.html?path=chromedriver/
官方镜像:http://chromedriver.storage.googleapis.com/index.html
验证安装
安装完成后,可以验证ChromeDriver是否正确安装并可用。请按照以下步骤进行:
打开终端或命令提示符窗口。
输入“chromedriver”(macOS / Linux)或“chromedriver.exe”(Windows)。
如果安装成功,将看到ChromeDriver的版本信息以及其他一些输出。

下载的版本不匹配 :
如果没有完全一致的版本,下载最相近的也是可以的;
3. 脚本
from selenium import webdriver
import time
driver=webdriver.Chrome()
#driver = webdriver.Firefox()
#driver = webdriver.Chrome()
# driver = webdriver.Edge()
url="http://www.baidu.com"
driver.get(url)
driver.find_element_by_id("kw").send_keys("Selenium") # 定位元素设置值
driver.find_element_by_id("su").click() # 定位 点击
time.sleep(10)
driver.quit()
4. 运行报错:

设置 驱动路径到环境变量或是将
把驱动文件所在目录添加到Path环境变量中(重启 pycharm)
或者直接放到Python安装目录,因为Python已添加到Path中
再次运行
