问题描述
由于超过2个小时,我试图在python容器中使用chrome设置Selenium,而在非容器高山上使用chrome.我不知道为什么会收到此错误消息:
Since more than 2 hours I'm trying to set Selenium in python with chrome on un container alpine. I don't know why I have this error message :
browser = webdriver.Chrome()
File "/usr/lib/python2.7/site-packages/selenium/webdriver/chrome/webdriver.py", line 68, in __init__
self.service.start()
File "/usr/lib/python2.7/site-packages/selenium/webdriver/common/service.py", line 83, in start
os.path.basename(self.path), self.start_error_message)
selenium.common.exceptions.WebDriverException: Message: 'chromedriver' executable needs to be in PATH. Please see https://sites.google.com/a/chromium.org/chromedriver/home
我不明白,因为google驱动程序位于路径外观中:
I don't understand because the google driver is in path look:
有人可以帮助我吗?非常感谢
Someone can help me please ? Thank a lot
PS:这是我的dockerfile的一部分
PS : this is a part of my dockerfile
RUN wget "https://chromedriver.storage.googleapis.com/2.36/chromedriver_linux64.zip" &&\
busybox unzip chromedriver_linux64.zip &&\
chmod a+x chromedriver &&\
mv chromedriver /usr/bin/
这是我的方法:
def __init__(self, url, parser = "lxml") :
self.url = url
self.parser = parser
browser = webdriver.Chrome()
browser.get(self.url)
...
ps:dockerfile:
ps : dockerfile :
