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:

  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

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

其他回答

如果要在Windows 10系统下添加驱动程序路径:

右键单击“这台PC”图标,选择“属性” 点击“高级系统设置” 点击屏幕底部的“环境变量” 在“用户变量”部分选中“路径”,然后点击“编辑” 通过点击“New”,输入你要添加的驱动程序的路径,然后按回车键,来添加变量的路径。 输入路径后,点击“确定” 继续点击“确定”,直到关闭所有屏幕

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?

一些额外的输入/澄清:

下面是Windows 7、Python 3.6和Selenium 3.11的分辨率:

dsalaj关于Unix的另一个答案的注释也适用于Windows;可以避免在Windows级别上修补PATH环境变量和重新启动Windows系统。

(1)下载geckdriver(如本线程前面所述),并将(解压)geckdriver.exe放在X:\Folder\of\your\choice

(2) Python代码示例:

import os;
os.environ["PATH"] += os.pathsep + r'X:\Folder\of\your\choice';

from selenium import webdriver;
browser = webdriver.Firefox();
browser.get('http://localhost:8000')
assert 'Django' in browser.title

注:

(1)上述代码打开指定URL的Firefox浏览器可能需要大约10秒的时间。

(2)如果没有服务器在指定的URL上运行,或者没有包含字符串'Django'的页面,Python控制台将显示以下错误:

selenium.common.exceptions.WebDriverException: Message: Reached error page: about:neterror?e = connectionFailure&u = http % 3 / / localhost % 3 a8000 / Firefox和c = UTF-8&f = regular&d = % 20可以% E2 % 80% 9

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

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。
