Firefox驱动程序无法为带有FF49和Python的Selenium 3.0.1启动

Question

我用Python编写了以下Selenium Webdriver脚本。但我有个错误：

from selenium import webdriver
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities

caps = DesiredCapabilities.FIREFOX
caps["marionette"] = True
driver = webdriver.Firefox(capabilities=caps)

driver.get("http://www.mahsumakbas.net")

print driver.title

driver.close()

错误是：

Traceback (most recent call last): File "C:\Mahsum\DevelopmentWorkSpace\Eclipse\Java\selenium_proj\src\hello.py", line 6, in driver = webdriver.Firefox(capabilities=caps) File "C:\Python27\lib\site-packages\selenium\webdriver\firefox\webdriver.py", line 135, in init self.service.start() File "C:\Python27\lib\site-packages\selenium\webdriver\common\service.py", line 71, in start os.path.basename(self.path), self.start_error_message) selenium.common.exceptions.WebDriverException: Message: 'geckodriver' executable needs to be in PATH.

Exception AttributeError: "'Service' object has no attribute 'process'" in > ignored

Selenium Webdriver版本为：3.0.1
火狐：49.0.2
壁虎：v0.11.1-win64

我将geckodriver path添加到Windows path变量中。在

你可以把geckodriver.exe放在Python的基本路径中，它就可以工作了。在

或者，如果您希望有一个干净的Python文件夹，那么在初始化时必须声明geckodriver的路径。或者每次运行脚本时都这样做，或者按照您所说的那样按路径执行。正如Naveen建议的，在正确保存路径之前需要重新启动。您也可以尝试在Windows命令行中运行：

setx path "%path%;c:\path\to\geckodriver-folder"
