无法使用Selenium打开Firefox浏览器

Question

当我尝试使用python脚本在Ubuntu Linux 14.04上打开firefox浏览器时收到此错误消息：

File "seleniumtest.py", line 3, in <module>
browser = webdriver.Firefox()
File "/usr/local/lib/python2.7/dist-packages/selenium/webdriver/firefox/webdriver.py", line 145, in __init__
self.service.start()
File "/usr/local/lib/python2.7/dist-packages/selenium/webdriver/common/service.py", line 74, in start
stdout=self.log_file, stderr=self.log_file)
File "/usr/lib/python2.7/subprocess.py", line 710, in __init__
errread, errwrite)
File "/usr/lib/python2.7/subprocess.py", line 1327, in _execute_child
raise child_exception
OSError: [Errno 8] Exec format error

示例代码是：

from selenium import webdriver
browser = webdriver.Firefox()
browser.get('https://www.google.com')

已经安装了像geckodriver这样的依赖关系。

wget https://github.com/mozilla/geckodriver/releases/download/v0.13.0/geckodriver-v0.13.0-linux64.tar.gz
tar -xvzf geckodriver-v0.13.0-linux64.tar.gz
rm geckodriver-v0.13.0-linux64.tar.gz
chmod +x geckodriver
cp geckodriver /usr/local/bin/

添加“executable_path =”/ usr / local / bin / geckodriver“后，输出如下：

File "seleniumtest.py", line 3, in <module>
browser = webdriver.Firefox(executable_path="/usr/local/bin/geckodriver")
File "/usr/local/lib/python2.7/dist-packages/selenium/webdriver/firefox/webdriver.py", line 145, in __init__
self.service.start()
File "/usr/local/lib/python2.7/dist-packages/selenium/webdriver/common/service.py", line 74, in start
stdout=self.log_file, stderr=self.log_file)
File "/usr/lib/python2.7/subprocess.py", line 710, in __init__
errread, errwrite)
File "/usr/lib/python2.7/subprocess.py", line 1327, in _execute_child
raise child_exception
OSError: [Errno 8] Exec format error

Answer 1

您应该提供已安装的geckodriver的位置：

browser = webdriver.Firefox(executable_path="/path/to/geckodriver")

Answer 2

有一种方法可以使用Firefox。 我们可以使用Chromium。 这些是设置步骤：

sudo apt-get --yes --force-yes install chromium-browser xvfb unzip

wget -N http://chromedriver.storage.googleapis.com/2.26/chromedriver_linux32.zip
unzip chromedriver_linux32.zip
chmod +x chromedriver

sudo mv -f chromedriver /usr/local/share/chromedriver
sudo ln -s /usr/local/share/chromedriver /usr/local/bin/chromedriver
sudo ln -s /usr/local/share/chromedriver /usr/bin/chromedriver

Answer 3

如果您使用的是Mac OS，请确保已在终端中运行此命令

chmod a+x geckodriver
