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

为Selenium Python设置geckodriver:

它需要用FirefoxDriver设置geckodriver路径，如下所示:

self.driver = webdriver.Firefox(executable_path = 'D:\Selenium_RiponAlWasim\geckodriver-v0.18.0-win64\geckodriver.exe')

下载适合您操作系统的geckodriver(从https://github.com/mozilla/geckodriver/releases)→将其解压到您选择的文件夹中→如上所述正确设置路径。

我在Windows 10上使用的是Python 3.6.2和Selenium WebDriver 3.4.3。

另一种设置geckodriver的方法:

i)简单地粘贴geckodriver.exe在/Python/Scripts/(在我的情况下，文件夹是:C:\Python36\Scripts) ii)现在编写如下简单代码:

self.driver = webdriver.Firefox()

其他回答

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

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。

Ubuntu 18.04+和最新发布的geckodriver

这应该也适用于其他类unix的变种。

export GV=v0.30.0
wget "https://github.com/mozilla/geckodriver/releases/download/$GV/geckodriver-$GV-linux64.tar.gz"
tar xvzf geckodriver-$GV-linux64.tar.gz
chmod +x geckodriver
sudo cp geckodriver /usr/local/bin/

Mac更新为:

geckodriver-$GV-macos.tar.gz

from webdriverdownloader import GeckoDriverDownloader # vs ChromeDriverDownloader vs OperaChromiumDriverDownloader
gdd = GeckoDriverDownloader()
gdd.download_and_install()
#gdd.download_and_install("v0.19.0")

这将为您提供Windows上gekodriver.exe的路径。

from selenium import webdriver
driver = webdriver.Firefox(executable_path=r'C:\\Users\\username\\\bin\\geckodriver.exe')
driver.get('https://www.amazon.com/')

最简单的方法为Windows!

从这里下载最新版本的geckodriver。将geckodriver.exe文件添加到Python目录(或PATH中已经存在的任何其他目录)。这应该能解决问题(在Windows 10上进行了测试)。
