Python 3.x Termux中的Firefox Selenium

我在termux中运行ubuntu，我安装pycharm来创建python代码。问题是我在操作webdriver时出错

我有最新的firefox（v59.0.2）、Selenium geckodriver v.0.24.0和python 3.6.5

这是代码的核心

from selenium import webdriver

driver = webdriver.Firefox('/root/Downloads/geckodriver')

这里是错误

根据您的第一次代码试用，此错误消息

FileNotFoundError: [Errno 2] No such file or directory: '/root/Downloads/geckodriver'

selenium.common.exceptions.WebDriverException: Message: 'geckodriver' executable needs to be in PATH.

…表示您的程序无法在上述目录中找到GeckoDriver

您可以在讨论中找到有关此错误的详细分析

根据您的第二次代码试用，此错误消息

FileNotFoundError: [Errno 2] No such file or directory: '/root/Downloads/geckodriver'

selenium.common.exceptions.WebDriverException: Message: 'geckodriver' executable needs to be in PATH.

…表示您的程序无法在上述目录中找到GeckoDriver

您可以在讨论中找到有关此错误的详细分析

解决方案 理想情况下，您需要：

• 确保GeckoDriver对非root用户具有可执行权限
• 以非root用户身份执行

  @Tests

• 使用以下代码块：

  from selenium import webdriver
  
  driver = webdriver.Firefox(executable_path=r'/non_root_user/Downloads/geckodriver')
  driver.get("http://google.com/")
  driver.quit()

只需将geckodriver文件复制到您的路径中即可。 类型 echo$PATH

---

要找到你的路径

如果你尝试绝对路径会发生什么

executable\u path='C:/path\u to\u root/root/Downloads/geckodriver

我相信C驱动器只适用于windows，我在termux bud中使用ubuntu。驱动器是什么并不重要，它只是一个例子。好吧，鉴于我并不真正了解这些东西，如何做到这一点？我的意思是我不知道用

path\u to\u root

替换什么。我只知道我的文件系统以/root/开头，对于bullet 1和3，我有termux，它是一个

virtualenv

，所以它是唯一的

root

用户，除非我有办法检查非root用户，我检查了权限及其所有读写，我还尝试将其放入

/usr/local/bin

中，结果是

意外退出。状态代码是：-4

对于bullet 2，我不知道，我是个新手
