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:

  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

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()

其他回答

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"):

我用的是Windows 10，这对我来说很管用:

从这里下载geckodriver。为您使用的计算机下载正确的版本。解压缩刚刚下载的文件，并剪切/复制其中包含的“。exe”文件导航到C:{你的python根文件夹}。我的是C:\Python27。将geckodriver.exe文件粘贴到此文件夹中。重新启动开发环境。尝试再次运行代码。现在应该可以了。

在macOS v10.12.1 (Sierra)和Python 2.7.10上，这对我来说是有效的:

def download(url):
    firefox_capabilities = DesiredCapabilities.FIREFOX
    firefox_capabilities['marionette'] = True
    browser = webdriver.Firefox(capabilities=firefox_capabilities,
                                executable_path=r'/Users/Do01/Documents/crawler-env/geckodriver')
    browser.get(url)
    return browser.page_source

此错误消息…

FileNotFoundError: [WinError 2] The system cannot find the file specified

.．.暗示您的程序无法定位指定的文件，并且在处理异常时发生了以下异常:

selenium.common.exceptions.WebDriverException: Message: 'geckodriver' executable needs to be in PATH.

．.．这意味着你的程序在启动/生成一个新的浏览上下文(即Firefox浏览器会话)的过程中无法定位GeckoDriver。

你可以从mozilla / GeckoDriver下载最新的GeckoDriver, unzip/untar并将GeckoDriver二进制文件/可执行文件存储在你系统中的任何位置，通过关键executable_path传递GeckoDriver的绝对路径，如下所示:

from selenium import webdriver

driver = webdriver.Firefox(executable_path='/path/to/geckodriver')
driver.get('http://google.com/')

如果firefox没有安装在默认位置(即安装在一个自定义位置)，另外你需要通过属性binary_location传递firefox二进制文件的绝对路径，如下所示:

# An Windows example
from selenium import webdriver
from selenium.webdriver.firefox.options import Options

options = Options()
options.binary_location = r'C:\Program Files\Mozilla Firefox\firefox.exe'
driver = webdriver.Firefox(firefox_options=options, executable_path=r'C:\WebDrivers\geckodriver.exe')
driver.get('http://google.com/')
