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

避免这种错误的新方法是使用Conda环境。

使用conda install -c conda-forge geckodriver，你不需要在路径中添加任何东西，也不需要编辑代码!

其他回答

在已经安装了Homebrew的macOS上，您可以简单地运行Terminal命令:

brew install geckodriver

因为Homebrew已经扩展了PATH，所以不需要修改任何启动脚本。

“geckodriver”可执行文件需要在PATH中。

首先，您需要从这里下载最新的可执行geckodriver，以使用Selenium运行最新的Firefox

实际上，Selenium客户端绑定试图从系统PATH中定位geckodriver可执行文件。您需要将包含可执行文件的目录添加到系统路径中。

On Unix systems you can do the following to append it to your system’s search path, if you’re using a Bash-compatible shell: export PATH=$PATH:/path/to/directory/of/executable/downloaded/in/previous/step On Windows you will need to update the Path system variable to add the full directory path to the executable geckodriver manually or command line** (don't forget to restart your system after adding executable geckodriver into system PATH to take effect)**. The principle is the same as on Unix.

现在你可以像下面这样运行你的代码:-

from selenium import webdriver

browser = webdriver.Firefox()

webdriverexception:消息:预期的浏览器二进制位置，但无法在默认位置找到二进制，没有'moz:firefoxOptions。提供Binary '功能，并且没有在命令行上设置二进制标志

该异常清楚地指出，您已经在其他位置安装了Firefox，而Selenium正试图从默认位置找到Firefox并启动，但它无法找到它。您需要显式提供Firefox安装的二进制位置来启动Firefox，如下所示

from selenium import webdriver
from selenium.webdriver.firefox.firefox_binary import FirefoxBinary

binary = FirefoxBinary('path/to/installed firefox binary')
browser = webdriver.Firefox(firefox_binary=binary)

Windows:

从GitHub下载文件，提取它，并粘贴到Python文件。这对我很管用。

https://github.com/mozilla/geckodriver/releases

对我来说，我的路径是:

C:\Users\MYUSERNAME\AppData\Local\Programs\Python\Python39

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

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。

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/')
