如何为 Windows 安装 Firefox 网络驱动程序？

Question

如何安装 Firefox 网络驱动程序以使用 selenium\python

我是用命令安装的

pip install selenium

我试过这段代码：

driver=webdriver.Firefox()
driver.get("https://www.google.com")
content=driver.find_element_by_id("lga")
print(content)

但它给了我这个错误

Traceback (most recent call last):
  File "C:\Users\Acer\AppData\Local\Programs\Python\Python37-32\lib\site-package

During handling of the above exception, another exception occurred:

Answer 1

有几件事要检查。

1) 您需要确保已安装 Firefox。
2) 获取最新的壁虎驱动here
3) 在您的环境中设置路径

export PATH=$PATH:/path/to/directory/of/executable/geckodriver<br>

4) 如果您打算跳过 3 ，则需要在脚本中修改此内容

from selenium.webdriver.firefox.firefox_binary import FirefoxBinary

binary = FirefoxBinary('C:\Firefox\Firefox.exe')
driver = webdriver.Firefox(firefox_binary=binary)
