Mac OS 用户在这里。我正在尝试在我的 python IDLE 中运行一个命令:
from selenium import webdriver
browser = webdriver.Firefox()
我收到以下错误消息:
Traceback (most recent call last):
File "/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/selenium/webdriver/common/service.py", line 76, in start

During handling of the above exception, another exception occurred:

selenium.common.exceptions.WebDriverException: Message: 'geckodriver' executable needs to be in PATH.
我已经运行
brew install geckodriver
,并且 which geckodriver
返回 /usr/local/bin/geckodriver
所以我确定它安装正确。但是,它似乎仍然无法正常运行? 最佳答案
你的错误信息很清楚:
FileNotFoundError: [Errno 2] No such file or directory: 'geckodriver': 'geckodriver'
您必须将路径设置为 geckodriver 。有不同的方法可以做到这一点。
您可以在代码中设置 geckodriver 的路径:
from selenium import webdriver
browser = webdriver.Firefox(executable_path=r'/.../path2Your/geckodriver')
或者在 PATH 环境变量中插入 geckodriver 的路径:
export PATH=$PATH:/.../path2Your/geckodriver
我从未尝试在 mac os 中移动
/usr/local/bin/
中的可执行文件。我在 ubuntu 操作系统中尝试过,它可以工作。我觉得应该没问题。可能是因为该文件不可执行。如果不是,请转到
/usr/local/bin/
并使其可执行:chmod +x geckodriver
关于python - 'geckodriver' 可执行文件需要在 PATH 中,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/50461779/
