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:

    stdout=self.log_file, stderr=self.log_file)
  File "C:\Python\Python35\lib\subprocess.py", line 947, in __init__
    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

在树莓派上，我必须从ARM驱动程序创建它，并在webdriver.py文件中设置geckodriver和日志路径:

sudo nano /usr/local/lib/python2.7/dist-packages/selenium/webdriver/firefox/webdriver.py

def __init__(self, firefox_profile=None, firefox_binary=None,
             timeout=30, capabilities=None, proxy=None,
             executable_path="/PATH/gecko/geckodriver",
             firefox_options=None,
             log_path="/PATH/geckodriver.log"):

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)。

对我来说，在相同的环境中安装geckodriver就足够了:

brew install geckodriver

代码并没有改变:

from selenium import webdriver
browser = webdriver.Firefox()

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。

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

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。
