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

我用的是Windows 10和Anaconda 2。我尝试设置系统路径变量，但它没有工作。然后我简单地将geckodriver.exe文件添加到Anaconda 2/Scripts文件夹中，现在一切都很好了。

对我来说，这条路是:

C:\Users\Bhavya\Anaconda2\Scripts

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')

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')

一些额外的输入/澄清:

下面是Windows 7、Python 3.6和Selenium 3.11的分辨率:

dsalaj关于Unix的另一个答案的注释也适用于Windows;可以避免在Windows级别上修补PATH环境变量和重新启动Windows系统。

(1)下载geckdriver(如本线程前面所述)，并将(解压)geckdriver.exe放在X:\Folder\of\your\choice

(2) Python代码示例:

import os;
os.environ["PATH"] += os.pathsep + r'X:\Folder\of\your\choice';

from selenium import webdriver;
browser = webdriver.Firefox();
browser.get('http://localhost:8000')
assert 'Django' in browser.title

注:

(1)上述代码打开指定URL的Firefox浏览器可能需要大约10秒的时间。

(2)如果没有服务器在指定的URL上运行，或者没有包含字符串'Django'的页面，Python控制台将显示以下错误:

selenium.common.exceptions.WebDriverException: Message: Reached error page: about:neterror?e = connectionFailure&u = http % 3 / / localhost % 3 a8000 / Firefox和c = UTF-8&f = regular&d = % 20可以% E2 % 80% 9

考虑安装一个容器化的Firefox:

docker pull selenium/standalone-firefox
docker run --rm -d -p 5555:4444 --shm-size=2g selenium/standalone-firefox

使用webdriver连接。远程:

driver = webdriver.Remote('http://localhost:5555/wd/hub', DesiredCapabilities.FIREFOX)
driver.set_window_size(1280, 1024)
driver.get('https://toolbox.googleapps.com/apps/browserinfo/')
driver.save_screenshot('info.png')

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
