python - Selenium with Python - Chromedriver 必须在 PATH 中

Question

自 2 个多小时以来，我试图在 un container alpine 上使用 chrome 在 python 中设置 Selenium。我不知道为什么会出现此错误消息:

    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，因为谷歌驱动程序在路径中:

有人可以帮助我吗？非常感谢

附言:这是我的 dockerfile 的一部分

    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: docker 文件:

我没有使用 Chrome，而是使用 firefox，这就是我所有的 dockerfile。这对我有用。我希望那会帮助你。玩得开心
