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'

    if self.process is None:

    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

这个步骤在Ubuntu和Firefox 50上为我解决了这个问题。

下载geckodriver 拷贝geckodriver到/usr/local/bin文件夹

不需要添加:

firefox_capabilities = DesiredCapabilities.FIREFOX
firefox_capabilities['marionette'] = True
firefox_capabilities['binary'] = '/usr/bin/firefox'
browser = webdriver.Firefox(capabilities=firefox_capabilities)

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()

也可以执行echo PATH (Linux)，并将geckodriver移动到您喜欢的文件夹。如果目标是系统(而不是虚拟环境)文件夹，则驱动程序将成为全局可访问的。

Windows用户

使用原始代码，因为它是:

from selenium import webdriver
browser = webdriver.Firefox()
driver.get("https://www.google.com")

然后从mozilla/geckodriver下载驱动

把它放在一个固定的路径(永久地)…作为一个例子，我把它放在:

C: \ Python35

然后进入系统的环境变量。在“系统变量”网格中寻找Path变量并添加:

; C: Python35喝geckodriver

Geckodriver，不是Geckodriver .exe。

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())

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')
