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>>

    self.stop()

    if self.process is None:
AttributeError: 'Service' object has no attribute 'process'
Traceback (most recent call last):

    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

在Ubuntu上手动安装geckodriver

访问https://github.com/mozilla/geckodriver/releases 下载最新版本“geckodriver-vX.XX.X-linux64.tar.gz” 解压缩tar -xvzf geckodriver-vX.XX.X-linux64.tar.gz 给geckodriver可执行权限(chmod +x geckodriver) 将geckodriver二进制文件移动到/usr/local/bin或系统路径上的任何位置。

Ubuntu上安装geckodriver的脚本:

#!/bin/bash

INSTALL_DIR="/usr/local/bin"

json=$(curl -s https://api.github.com/repos/mozilla/geckodriver/releases/latest)
url=$(echo "$json" | jq -r '.assets[].browser_download_url | select(contains("linux64"))')
curl -s -L "$url" | tar -xz
chmod +x geckodriver
sudo mv geckodriver "$INSTALL_DIR"
echo "installed geckodriver binary in $INSTALL_DIR"

这个答案完全抄袭自: Corey Goldberg对如何在Ubuntu中安装geckodriver的回答?

其他回答

在macOS v10.12.1 (Sierra)和Python 2.7.10上，这对我来说是有效的:

def download(url):
    firefox_capabilities = DesiredCapabilities.FIREFOX
    firefox_capabilities['marionette'] = True
    browser = webdriver.Firefox(capabilities=firefox_capabilities,
                                executable_path=r'/Users/Do01/Documents/crawler-env/geckodriver')
    browser.get(url)
    return browser.page_source

如果你使用虚拟环境和Windows 10(可能其他系统也一样)，你只需要把geckodriver.exe放到虚拟环境目录下的以下文件夹中:

... my_virtual_env_directory \ \ geckodriver脚本。exe

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())

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

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!
