WebDriverException：“GeckoDriver”可执行文件需要在路径中，即使它是

Question

试图让firefox在Spyder中使用selenium运行。我当前的代码是

from selenium import webdriver
import os
os.environ["PATH"] += ":/usr/local/bin/geckodriver"
browser = webdriver.Firefox()

我仍然得到这个错误：

runfile('/Users/mherl/Dropbox/AnacondaProjects/MWS/MWSSpyder/test.py', 
wdir='/Users/mherl/Dropbox/AnacondaProjects/MWS/MWSSpyder')
Traceback (most recent call last):

WebDriverException: 'geckodriver' executable needs to be in PATH. 

尽管gekodriver在那个文件夹中。

/usr/local/bin

/usr/local/bin

如果这很重要的话，这是一个运行高塞拉的mac。

此错误消息...

WebDriverException: 'geckodriver' executable needs to be in PATH. 

...暗示在预期的默认位置没有找到GeckoDriver。

当您使用基于MAC的系统时，您需要传递executable_path键以及引用GeckoDriver绝对路径的值，如下所示：

from selenium import webdriver

browser = webdriver.Firefox(executable_path='/usr/local/bin/geckodriver')
