WindowsError: [Error 2] The system cannot find the file specified
当我在ipython笔记本中使用Selenium打开Firefox时出错。错误完全匹配。有人知道问题是什么吗?我是怎么解决的?我用的是火狐22。我输入的代码如下:from selenium import webdriver
driver = webdriver.Firefox()
The error the code returns is as follows:
WindowsError Traceback (most recent call last)

尝试在初始化Firefox()时指定Firefox二进制文件
from selenium import webdriver
from selenium.webdriver.firefox.firefox_binary import FirefoxBinary
binary = FirefoxBinary('path/to/binary')
driver = webdriver.Firefox(firefox_binary=binary)
默认的路径FirefoxDriver在%PROGRAMFILES%\Mozilla Firefox\firefox.exe中查找。查看firefoxdriver或将Firefox二进制文件的路径添加到Windows路径。
当我设置环境变量export PYTHONDONTWRITEBYTECODE=1以在每次测试运行时删除pyc文件时,我得到了同样的错误。我可以通过更新selenium pip安装—升级selenium来恢复更改。OSX(10.10) 一种解决方法
apt-get updateap -get install -y xorg xvfb firefox dbus-x11 xfonts-100dpi xfonts-75dpi xfonts-cyrillic 这两个包是必需的(ubuntu)!
apt-get update
apt-get install -y xorg xvfb firefox dbus-x11 xfonts-100dpi xfonts-75dpi xfonts-cyrillic
sudo apt-get install build-essential curl git m4 ruby texinfo libbz2-dev libcurl4-openssl-dev libexpat-dev libncurses-dev zlib1g-dev
sudo apt install linuxbrew-wrapper
brew install geckodriver
使用chrome而不是火狐更有效的方法是查看本教程
https://christopher.su/2015/selenium-chromedriver-ubuntu/ driver=webdriver.Firefox(executable_path="add geckodriver.exe",log_path=None) 可以的,挺不错
