python - geckodriver 可执行文件需要在路径中

Question

我已阅读之前关于此主题的问题并尝试遵循建议，但我仍然遇到错误。在终端上，我跑了

export PATH=$PATH:/Users/Conger/Documents/geckodriver-0.8.0-OSX

我也试过

    export PATH=$PATH:/Users/Conger/Documents/geckodriver

当我运行以下 Python 代码时

from selenium import webdriver
from selenium.webdriver.firefox.firefox_binary import FirefoxBinary
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities


firefox_capabilities = DesiredCapabilities.FIREFOX
firefox_capabilities['marionette'] = True
firefox_capabilities['binary'] = '/Users/Conger/Documents/Firefox.app'

driver = webdriver.Firefox(capabilities=firefox_capabilities)

我仍然得到以下错误

Python - testwebscrap.py:8
Traceback (most recent call last):
  File "/Users/Conger/Documents/Python/Crash_Course/testwebscrap.py", line 11, in <module>
    driver = webdriver.Firefox(capabilities=firefox_capabilities)

您可以通过以下方式降级您的 Selenium

pip install selenium==2.53.6

这解决了我的问题
