Termux 中的 Firefox Selenium

Question

我在 termux 中运行 ubuntu，我安装了 pycharm 来创建 python 代码。问题是我在打开 webdriver 时遇到了一些错误。

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

这是代码

from selenium import webdriver

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

这是错误

Traceback (most recent call last):
   File "<input>", line 3, in <module>
   File "/root/PycharmProjects/untitled/venv/lib/python3.6/site-packages/selenium/webdriver/firefox/webdriver.py", line 151, in __init__
firefox_profile = FirefoxProfile(firefox_profile)
  File "/root/PycharmProjects/untitled/venv/lib/python3.6/site-packages/selenium/webdriver/firefox/firefox_profile.py", line 80, in __init__
    ignore=shutil.ignore_patterns("parent.lock", "lock", ".parentlock"))
  File "/usr/lib/python3.6/shutil.py", line 309, in copytree
names = os.listdir(src)
FileNotFoundError: [Errno 2] No such file or directory: '/root/Downloads/geckodriver'

如果我这样做

from selenium import webdriver

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

这是错误

    Traceback (most recent call last):
    File "/root/PycharmProjects/untitled/venv/lib/python3.6/site-packages/selenium/webdriver/common/service.py", line 76, in start
    stdin=PIPE)
  File "/usr/lib/python3.6/subprocess.py", line 709, in __init__
    restore_signals, start_new_session)

    raise child_exception_type(errno_num, err_msg, err_filename)
FileNotFoundError: [Errno 2] No such file or directory: '/root/Downloads/geckodriver': '/root/Downloads/geckodriver'
During handling of the above exception, another exception occurred:

Answer 1

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'

...表示您的程序无法在上述目录中找到 GeckoDriver。

您可以在讨论FileNotFoundError: [Errno 2] No such file or directory: 'geckodriver': 'geckodriver' with GeckoDriver and Python in MAC OS中找到对此错误的详细分析

根据您的第二次代码试用此错误消息...

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WebDriverException: 'geckodriver' executable needs to be in PATH even though it is中找到对此错误的详细分析

解决方案

理想情况下，您需要：

• 确保 GeckoDriver 对 非 root 用户具有 executable 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()
  

Answer 2

只需将 geckodriver 文件复制到您的 PATH 中即可。 类型 回声 $PATH 找到你的路径
