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:

    if self.process is None:

  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

Ubuntu 18.04+和最新发布的geckodriver

这应该也适用于其他类unix的变种。

export GV=v0.30.0
wget "https://github.com/mozilla/geckodriver/releases/download/$GV/geckodriver-$GV-linux64.tar.gz"
tar xvzf geckodriver-$GV-linux64.tar.gz
chmod +x geckodriver
sudo cp geckodriver /usr/local/bin/

Mac更新为:

geckodriver-$GV-macos.tar.gz

其他回答

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。

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

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

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)

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!
