我正在用Python文本阅读Sweigart的《自动化无聊的东西》。我正在使用IDLE,并且已经安装了Selenium模块和Firefox浏览器。

每当我试图运行webdriver函数,我得到这个:

from selenium import webdriver
browser = webdriver.Firefox()

例外:

Exception ignored in: <bound method Service.__del__ of <selenium.webdriver.firefox.service.Service object at 0x00000249C0DA1080>>
Traceback (most recent call last):
  File "C:\Python\Python35\lib\site-packages\selenium\webdriver\common\service.py", line 163, in __del__
    self.stop()
  File "C:\Python\Python35\lib\site-packages\selenium\webdriver\common\service.py", line 135, in stop
    if self.process is None:

  File "C:\Python\Python35\lib\subprocess.py", line 1224, in _execute_child
    startupinfo)
FileNotFoundError: [WinError 2] The system cannot find the file specified

在处理上述异常时,发生了另一个异常:

Traceback (most recent call last):
  File "<pyshell#11>", line 1, in <module>
    browser = webdriver.Firefox()
  File "C:\Python\Python35\lib\site-packages\selenium\webdriver\firefox\webdriver.py", line 135, in __init__
    self.service.start()
  File "C:\Python\Python35\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.

我想我需要为geckodriver设置路径,但我不确定如何,所以我该如何做到这一点?


当前回答

确保您有正确版本的驱动程序(geckodriver), x86或64。 确保您正在检查正确的环境。例如,作业在Docker容器中运行,而环境在主机操作系统上检查。

其他回答

在Windows 10上,我下载geckodriver.exe就可以了。我只是更新了火狐浏览器。

下面是我使用的代码:

from selenium import webdriver
driver = webdriver.Firefox(
    executable_path=r'C:\Users\Usuario\Desktop\Automate the boring stuff with python exercises\Web Scraping\geckodriver.exe')
driver.get('http://inventwithpython.com')

如果您在Linux上,可以使用一个简单的命令来解决这个问题

首先,下载(https://github.com/mozilla/geckodriver/releases)并解压ZIP文件 打开解压的文件夹 从文件夹(解压后geckodriver文件所在的文件夹)打开终端 现在在您的终端上运行这个简单的命令,将geckodriver复制到正确的文件夹中: Sudo cp geckodriver /usr/local/bin

默认不安装Geckodriver。

geckodriver

输出:

Command 'geckodriver' not found, but it can be installed with:

sudo apt install firefox-geckodriver

下面的命令不仅安装它,而且还将它放在可执行PATH中。

sudo apt install firefox-geckodriver

这个问题只需要一步就解决了。我和你有完全一样的错误,我一安装它就消失了。去吧,试一试。

which geckodriver

输出:

/usr/bin/geckodriver

geckodriver

输出:

1337    geckodriver    INFO    Listening on 127.0.0.1:4444
^C

如果你使用虚拟环境和Windows 10(可能其他系统也一样),你只需要把geckodriver.exe放到虚拟环境目录下的以下文件夹中:

... my_virtual_env_directory \ \ geckodriver脚本。exe

在树莓派上,我必须从ARM驱动程序创建它,并在webdriver.py文件中设置geckodriver和日志路径:

sudo nano /usr/local/lib/python2.7/dist-packages/selenium/webdriver/firefox/webdriver.py
def __init__(self, firefox_profile=None, firefox_binary=None,
             timeout=30, capabilities=None, proxy=None,
             executable_path="/PATH/gecko/geckodriver",
             firefox_options=None,
             log_path="/PATH/geckodriver.log"):
