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

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。

确保您有正确版本的驱动程序(geckodriver)， x86或64。确保您正在检查正确的环境。例如，作业在Docker容器中运行，而环境在主机操作系统上检查。

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')

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/')

对于Ubuntu 16.04 (Xenial Xerus)及更高版本，您可以这样做:

Firefox: Sudo apt-get install firefox-geckodriver

铬: 安装chromium-chromedriver

如果你正在使用Anaconda，你所要做的就是激活你的虚拟环境，然后使用以下命令安装geckodriver:

    conda install -c conda-forge geckodriver
