geckodriver 没有在 ubuntu 上使用 selenium 和 django 打开 firefox

Question

我花了一整天的时间来解决这个问题。我的 selenium 代码与 chromedriver 和 geckodriver 在 Windows 上完美配合，我需要 celery，我最好的选择是切换到我的 ubuntu 操作系统（版本 20）。如果应该显示抓取的数据的页面显示消息：连接被拒绝。 geckodriver 是 26 版 这是错误。

File "/home/maro/Desktop/crypto/cert/lib/python3.8/site-packages/django/core/handlers/exception.py", line 34, in inner
    response = get_response(request)
  File "/home/maro/Desktop/crypto/cert/lib/python3.8/site-packages/django/core/handlers/base.py", line 115, in _get_response
    response = self.process_exception_by_middleware(e, request)
  File "/home/maro/Desktop/crypto/cert/lib/python3.8/site-packages/django/core/handlers/base.py", line 113, in _get_response
    response = wrapped_callback(request, *callback_args, **callback_kwargs)
  File "/home/maro/Desktop/crypto/forex/views.py", line 80, in pricelist
    driver = webdriver.Firefox(executable_path='/usr/bin/geckodriver')
  File "/home/maro/Desktop/crypto/cert/lib/python3.8/site-packages/selenium/webdriver/firefox/webdriver.py", line 170, in __init__
    RemoteWebDriver.__init__(
  File "/home/maro/Desktop/crypto/cert/lib/python3.8/site-packages/selenium/webdriver/remote/webdriver.py", line 157, in __init__
    self.start_session(capabilities, browser_profile)
  File "/home/maro/Desktop/crypto/cert/lib/python3.8/site-packages/selenium/webdriver/remote/webdriver.py", line 252, in start_session
    response = self.execute(Command.NEW_SESSION, parameters)
  File "/home/maro/Desktop/crypto/cert/lib/python3.8/site-packages/selenium/webdriver/remote/webdriver.py", line 321, in execute
    self.error_handler.check_response(response)
  File "/home/maro/Desktop/crypto/cert/lib/python3.b/site-packages/selenium/webdriver/remote/errorhandler.py", line 242, in check_response
    raise exception_class(message, screen, stacktrace)
selenium.common.exceptions.TimeoutException: Message: connection refused

我已将我的 Firefox 从 75 版更新到 80 版，但仍然没有任何变化。我已经多次更改驱动程序路径，但错误仍然保持不变。

这是我的 geckodriver 日志

1594416320001   mozrunner::runner   INFO    Running command: "/usr/bin/firefox" "-marionette" "-foreground" "-no-remote" "-profile" "/tmp/rust_mozprofileS5CJqR"

geckodriver 是可执行的，我还检查了主机以查看 localhost 是否附加到 127.0.... url，是的，它是。我完全糊涂了

这是我的观点.py

import time
import selenium
from django.shortcuts import render
from django.contrib.auth import login, authenticate, logout
from .forms import SignUpForm
from django.shortcuts import render, redirect

from selenium import webdriver
from selenium.webdriver.firefox.options import Options
from selenium.webdriver.common.by import By
def pricelist(request):
    driver = webdriver.Firefox(executable_path='/usr/bin/geckodriver')
    driver.get('')
    data = []
    while not data:

        
        for elm in driver.find_elements(By.CSS_SELECTOR, "span[data-field=CPT]"):
            if elm.text and elm.text != '-':
                data.append(elm.text)
                
            
        time.sleep(3)
           
    context = {
        "price": 123,
        "mydata": data
    }

    return render(request, 'pricelist.html', context)

我已经让它工作了。我切换到 chromedriver，遇到了类似的问题，发现 chromedriver 使用与我的 Django 应用程序相同的端口。我将我的 Django 应用程序的端口更改为 8001，使用 python manage.py runserver 8001
