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:

  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

这个步骤在Ubuntu和Firefox 50上为我解决了这个问题。

下载geckodriver 拷贝geckodriver到/usr/local/bin文件夹

不需要添加:

firefox_capabilities = DesiredCapabilities.FIREFOX
firefox_capabilities['marionette'] = True
firefox_capabilities['binary'] = '/usr/bin/firefox'
browser = webdriver.Firefox(capabilities=firefox_capabilities)

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

访问Gecko Driver并从下载部分获得Gecko驱动程序的URL。

克隆这个存储库:https://github.com/jackton1/script_install.git

cd script_install

Run

./installer --gecko-driver https://github.com/mozilla/geckodriver/releases/download/v0.18.0/geckodriver-v0.25.0-linux64.tar.gz

令人遗憾的是，没有一本关于Selenium/Python的书籍以及通过谷歌发表的关于这个问题的大多数评论都没有清楚地解释在Mac上设置这个的路径逻辑(一切都是Windows!)YouTube上的视频都是在你设置好路径之后(在我看来，这是最便宜的出路!)所以，对于你优秀的Mac用户来说，使用下面的命令来编辑你的Bash路径文件:

touch ~/.bash_profile; open ~/.bash_profile*

然后添加一个类似....的路径

# Setting PATH for geckodriver
PATH=“/usr/bin/geckodriver:${PATH}”
export PATH

# Setting PATH for Selenium Firefox
PATH=“~/Users/yourNamePATH/VEnvPythonInterpreter/lib/python2.7/site-packages/selenium/webdriver/firefox/:${PATH}”
export PATH

# Setting PATH for executable on Firefox driver
PATH=“/Users/yournamePATH/VEnvPythonInterpreter/lib/python2.7/site-packages/selenium/webdriver/common/service.py:${PATH}”
export PATH*

这对我很管用。
