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

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。

其他回答

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

我用的是Windows 10，这对我来说很管用:

从这里下载geckodriver。为您使用的计算机下载正确的版本。解压缩刚刚下载的文件，并剪切/复制其中包含的“。exe”文件导航到C:{你的python根文件夹}。我的是C:\Python27。将geckodriver.exe文件粘贴到此文件夹中。重新启动开发环境。尝试再次运行代码。现在应该可以了。

# Setting PATH for Selenium Firefox

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。

避免这种错误的新方法是使用Conda环境。

使用conda install -c conda-forge geckodriver，你不需要在路径中添加任何东西，也不需要编辑代码!

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()
