Selenium with Python - Chromedriver 必须在 PATH 中

Question

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

I don't understand because the google driver is in path look:

Someone can help me please ? Thank a lot

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/

this is my methode :

    def __init__(self, url, parser = "lxml") :
       self.url = url
       self.parser = parser
       browser = webdriver.Chrome()
       browser.get(self.url)
       ...

ps : dockerfile :
