Selenium使用Python - Geckodriver可执行文件需要在PATH中

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:
AttributeError: 'Service' object has no attribute 'process'
Exception ignored in: <bound method Service.__del__ of <selenium.webdriver.firefox.service.Service object at 0x00000249C0E08128>>

    self.stop()

    if self.process is None:
AttributeError: 'Service' object has no attribute 'process'

    stdout=self.log_file, stderr=self.log_file)
  File "C:\Python\Python35\lib\subprocess.py", line 947, in __init__
    restore_signals, start_new_session)
  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

这为我解决了问题。

from selenium import webdriver
driver = webdriver.Firefox(executable_path=r'your\path\geckodriver.exe')
driver.get('http://inventwithpython.com')

其他回答

对我来说，在相同的环境中安装geckodriver就足够了:

brew install geckodriver

代码并没有改变:

from selenium import webdriver
browser = webdriver.Firefox()

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"):

我看到讨论仍然在讨论通过下载二进制文件和手动配置路径来设置geckodriver的旧方法。

这可以使用webdriver-manager自动完成

pip install webdriver-manager

现在问题中的上面代码将简单地与下面的更改一起工作，

from selenium import webdriver
from webdriver_manager.firefox import GeckoDriverManager

driver = webdriver.Firefox(executable_path=GeckoDriverManager().install())

MacBook用户:

步骤1:

打开此链接并复制Homebrew路径，粘贴到终端并安装。

步骤2:

brew install geckodriver

步骤3:

pip install webdriver-manager

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')
