如何处理 selenium 和 geckodriver 安装错误？

Question

我通过安装 selenium 和 django 模块来运行以下代码。

from selenium import webdriver 
browser = webdriver.Firefox()
browser.get('http://localhost:8000') 
assert 'Django' in browser.title

对于 selenium 模块，我需要 geckodriver 用于 firefox 浏览器。因此，我通过不同的方式安装了 geckodriver - 1.npm，2.brew，3.直接安装（从 here 下载并将其移动到 /usr/local/bin 或 /usr/bin。所有方法都没有为上面的测试代码工作。

我收到以下错误消息：

Traceback (most recent call last):
  File "functional_tests.py", line 3, in <module>
    browser.get('http://localhost:8000') 
  File "/Users/kiyeonj/opt/anaconda3/envs/tdd_practice/lib/python3.8/site-packages/selenium/webdriver/remote/webdriver.py", line 333, in get

请让我知道问题是什么..

我想你也需要一个 gecko 驱动程序。

您可以从here

下载

并将其放入一个文件夹中，最好是 .py files

然后像这样使用它:-

from selenium import webdriver
driver = webdriver.Firefox(executable_path = "D:\geckodriver.exe")
driver.maximize_window()
browser.get('http://localhost:8000')
assert 'Django' in browser.title

PS :

executable_path = 'full file path to your gecko driver'
