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()

    if self.process is None:

  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

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)。

默认不安装Geckodriver。

geckodriver

输出:

Command 'geckodriver' not found, but it can be installed with:

sudo apt install firefox-geckodriver

下面的命令不仅安装它,而且还将它放在可执行PATH中。

sudo apt install firefox-geckodriver

这个问题只需要一步就解决了。我和你有完全一样的错误,我一安装它就消失了。去吧,试一试。

which geckodriver

输出:

/usr/bin/geckodriver

geckodriver

输出:

1337    geckodriver    INFO    Listening on 127.0.0.1:4444
^C

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。

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())
