最近初看selenium,在python上进行自动化测试,就卡在启动上,第一个demo就测不过去
pip安装了selenium,也下载了chromedriver和geckodriver,也按照官网的要求把driver都放在了/usr/local/bin/目录下
然后把下面代码存入文件test.py
from selenium import webdriver browser = webdriver.Firefox() browser.get(‘http://baidu.com‘)
然后执行 python test.py,不论使用webdriver.Chrome()还是webdriver.Firefox(),以及在这个函数里面放置各种参数,最终都会报如下错误:
Traceback (most recent call last): File "pro/web_scraping/test2.py", line 3, in <module> browser = webdriver.Firefox() File "/Users/xxx/.local/lib/python3.8/site-packages/selenium/webdriver/firefox/webdriver.py", line 164, in __init__ self.service.start() File "/Users/xxx/.local/lib/python3.8/site-packages/selenium/webdriver/common/service.py", line 104, in start raise WebDriverException("Can not connect to the Service %s" % self.path) selenium.common.exceptions.WebDriverException: Message: Can not connect to the Service geckodriver
试过各种方法,找个各种解决方案,内网外网都翻了许多答案,都没有解决问题
今天甚至我nodejs都做了个demo去测试,然后成功了。然后就更蛋疼了。。。
今天看到这个帖子,豁然开朗
ping localhost,然后没ping通
(base2) ? ~ ping localhost ping: cannot resolve localhost: Unknown host (base2) ? ~ ping localhost ping: cannot resolve localhost: Unknown host (base2) ? ~ ping localhost ping: cannot resolve localhost: Unknown host (base2) ? ~ ping localhost ping: cannot resolve localhost: Unknown hosts
甚至不死心,还多试了几次,在配置了hosts之后,再ping了一次通了,发现能吊起来Chrome和Firefox了,Cool
再次运行python test.py
因为使用hosts,推荐个软件:https://apps.apple.com/cn/app/helm-hosts-%E6%96%87%E4%BB%B6%E7%AE%A1%E7%90%86/id1099472017?ign-mpt=uo%3D8&mt=12
