在 AWS EC2 linux 中运行 selenium webdriver

Question

我在 Amazon Linux AMI 上安装了 selenium。我尝试使用 python 来激活它。 错误出现。我不知道应该是什么意思。 chrome webdriver 可以在那个环境下运行吗？

我的代码

from selenium import webdriver
driver = webdriver.Chrome("/home/ec2-user/dlfjj/bin/chromedriver")

错误

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/ec2-user/dlfjj/local/lib/python2.7/site-packages/selenium/webdriver/chrome/webdriver.py", line 62, in __init__
self.service.start()
  File "/home/ec2-user/dlfjj/local/lib/python2.7/site-packages/selenium/webdriver/common/service.py", line 86, in start
os.path.basename(self.path), self.start_error_message)
selenium.common.exceptions.WebDriverException: Message: 'chromedriver' executable may have wrong permissions. Please see https://sites.google.com/a/chromium.org/chromedriver/home` 

更新： 出现新错误。

Answer 1

错误状态...

'chromedriver' executable may have wrong permissions

... 表示无法执行。如果您在 EC2 实例中添加执行位，它应该可以工作

$ chmod +x /home/ec2-user/dlfjj/bin/chromedriver
