无法让 Selenium Geckodriver 在 Python 上工作 - Mac OSX High Sierra

Question

我一直在努力让用于 Firefox 的 Selenium Geckodriver 在我的 Mac 上运行一段时间，但我就是无法让它运行。

如文档所示，我的 /usr/local/bin/ 目录中有 geckodriver 二进制文件。

每当我尝试执行以下操作时：

from selenium import webdriver
browser = webdriver.Firefox()
type(browser)
browser.get('www.google.com')enter code here

我在 Python 控制台中收到以下错误。

Traceback (most recent call last):
  File "/Users/maxmorin/.thonny/BundledPython36/lib/python3.6/site-
packages/selenium/webdriver/common/service.py", line 74, in start
stdout=self.log_file, stderr=self.log_file)

FileNotFoundError: [Errno 2] No such file or directory: 'geckodriver'

During handling of the above exception, another exception occurred:

Answer 1

您必须设置壁虎驱动程序的路径。一种方法如下：

driver = webdriver.Firefox(profile, executable_path=r'/pathTo/geckodriver')
driver.get("https://www.google.com")

确保文件是可执行的：

• chmod +x geckodriver++

编辑

如果您不想在代码中指定 executable_path，则必须将其添加到 PATH 环境变量中：

export PATH=$PATH:/path/to/geckodriver
