Mac OS用户在这里。我正在尝试在我的python IDLE中运行命令:
from selenium import webdriver
browser = webdriver.Firefox()
我收到以下错误消息:
Traceback (most recent call last):

During handling of the above exception, another exception occurred:

selenium.common.exceptions.WebDriverException: Message: 'geckodriver' executable needs to be in PATH.
我跑了brew install geckodriver
,which geckodriver
返回/usr/local/bin/geckodriver
所以我确定它安装正确。看来它仍然没有正常运行?
您的错误消息非常清楚:
FileNotFoundError: [Errno 2] No such file or directory: 'geckodriver': 'geckodriver'
您必须设置geckodriver的路径。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。我试过一个ubuntu操作系统,它的工作原理。我认为应该没问题。
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
对我来说最有效的一件事就是复制可执行的geckodriver文件。
进入bin文件夹:
如果您在Linux上,您可以在以下位置找到它:
/home/user_name/.local/bin
在这里粘贴你的geckodriver exe。
所以你的最终代码应该是这样的:
from selenium import webdriver
driver = webdriver.Firefox(executable_path = 'geckodriver')
这对我来说很有魅力,但我不确定它是否是正确的方式。
