無法讓Selenium Geckodriver在Python上運行-Mac OSX High Sierra

Question

我一直在努力讓Firefox的Selenium Geckodriver在我的Mac上運行一段時間，但我無法使其正常運行。

如文檔所示，我的/ usr / local / bin /目錄中有geckodriver二進制文件。

每當我嘗試執行以下命令時：

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

我在Python控制台中收到以下錯誤。

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)

raise child_exception_type(errno_num, err_msg)
FileNotFoundError: [Errno 2] No such file or directory: 'geckodriver'

During handling of the above exception, another exception occurred:

Answer 1

您必須設置壁虎驅動程序的路徑。 一種方法如下：

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

確保該文件是可執行文件：

• chmod + x壁虎驅動程序++

編輯

如果您不想在代碼中指定可執行文件路徑，則必須在PATH環境變量中添加它：

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