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'
Exception ignored in: <bound method Service.__del__ of <selenium.webdriver.firefox.service.Service object at 0x00000249C0E08128>>

  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'
Traceback (most recent call last):
  File "C:\Python\Python35\lib\site-packages\selenium\webdriver\common\service.py", line 64, in start
    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

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())

其他回答

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"):

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

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

也可以执行echo PATH (Linux)，并将geckodriver移动到您喜欢的文件夹。如果目标是系统(而不是虚拟环境)文件夹，则驱动程序将成为全局可访问的。

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
