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

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')

其他回答

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。

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
^C

考虑安装一个容器化的Firefox:

docker pull selenium/standalone-firefox
docker run --rm -d -p 5555:4444 --shm-size=2g selenium/standalone-firefox

使用webdriver连接。远程:

driver = webdriver.Remote('http://localhost:5555/wd/hub', DesiredCapabilities.FIREFOX)
driver.set_window_size(1280, 1024)
driver.get('https://toolbox.googleapps.com/apps/browserinfo/')
driver.save_screenshot('info.png')

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

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
