Could not find a version that satisfy the requirement geckodriver==0.24.0 (from -r /app/requirements.txt (line 4)) selenium Geckodriver 错误

Question

我的本地机器没有问题。但是当我将它部署在云服务器中时，特别是在 Scrapinghub 中我需要添加 geckodriver

如何在我的 requirement.txt 中包含 geckodriver？

这是我的工作代码

 from selenium import webdriver
 from selenium.webdriver.support.ui import WebDriverWait
 from selenium.webdriver.common.by import By
 from selenium.webdriver.support import expected_conditions as EC
 from selenium.webdriver.common.desired_capabilities import DesiredCapabilities
 from selenium.webdriver.firefox.firefox_binary import FirefoxBinary

 def parse_subpage(self, response):

        profile = webdriver.FirefoxProfile()
        profile.set_preference("network.proxy.type", 1)
        profile.set_preference("network.proxy.http", 
                    "localhost")
        profile.set_preference("network.proxy.http_port", 
                    3128)
        profile.update_preferences()

        capabilities = webdriver.DesiredCapabilities().FIREFOX
        capabilities["marionette"] = True
        driver = webdriver.Firefox(capabilities=capabilities, 
                    firefox_profile=profile)

        driver.get('sample.com')
        driver.quit()

我的Requirement.txt

mysql-connector-python
pytz==2018.9
selenium==3.13.0
geckodriver==0.24.0

观察到的错误：

ERROR: Could not find a version that satisfies the requirement geckodriver==0.24.0 (from -r /app/requirements.txt (line 4)) (from versions: none)

Answer 1

这个错误信息...

Could not find a version that satisfies the requirement geckodriver==0.24.0 (from -r /app/requirements.txt (line 4)) (from versions: none)

...表示 GeckoDriver 尝试通过 Firefox.[=13= 启动浏览会话时出错]

geckodriver==0.24.0和selenium==3.13.0[之间似乎没有不兼容 =43=] 根据 Supported platforms.

中的文档
据推测，这看起来像是 Mozilla Firefox 安装位置的问题。 Firefox 未安装在您的系统中，或者 Firefox 未安装在 default（所需）位置.

解决方案

您需要在默认位置安装 Firefox。如果 Firefox 安装在 自定义 位置，您需要传递 [=25] 的 绝对路径 =]firefox binary如下：

from selenium import webdriver from selenium.webdriver.firefox.firefox_binary import FirefoxBinary capabilities = webdriver.DesiredCapabilities().FIREFOX capabilities["marionette"] = True binary = FirefoxBinary('C:/Program Files/Mozilla Firefox/firefox.exe') driver = webdriver.Firefox(firefox_binary=binary, capabilities=capabilities, executable_path="C:/Utility/BrowserDrivers/geckodriver.exe") driver.get("http://www.google.com")
