NS_ERROR_SOCKET_ADDRESS_IN_USE [英] NS_ERROR_SOCKET_ADDRESS_IN_USE

问题描述

我的代码:

from selenium import webdriver
import selenium.webdriver.support.ui as ui
import time
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By

driver = webdriver.Firefox()
driver.get("https://www.youtube.com")
login_wait = WebDriverWait(driver, 10)

textbox = login_wait.until(EC.visibility_of_element_located((By.ID, 'search')))
textbox.send_keys("a")

time.sleep(10)
driver.close()

在Python控制台中没有错误，但geckodriver.log:

No error in Python console but geckodriver.log:

推荐答案

如果您在错误堆栈跟踪中查找，则错误说明了一切:

If you look ino the error stack trace, the error says it all :

1514074509913   Marionette  ERROR   Error on starting server: [Exception... "Component returned failure code: 0x804b0036 (NS_ERROR_SOCKET_ADDRESS_IN_USE) [nsIServerSocket.initSpecialConnection]"  nsresult: "0x804b0036 (NS_ERROR_SOCKET_ADDRESS_IN_USE)"  location: "JS frame :: chrome://marionette/content/server.js :: MarionetteServer.prototype.start :: line 95"  data: no]

这实际上意味着 Marionette 试图通过端口在您的 localhost 即 127.0.0.1 上打开您的连接> 49865 ，但由于以下原因之一，当前端口已被占用:

This essentially means Marionette is trying to open up a connection on you localhost i.e. 127.0.0.1 through port 49865 but the port is currently occupied due to one of the following reasons :

• Port 49865 当前正在由 localhost 用尽的其他一些应用程序使用.
• Port 49865 由您的 localhost 运行的某些服务使用.
• Port 49865 尚未被悬空的WebDriver变体实例释放，例如GeckoDriver，ChromeDriver，IEDriverServer或GhostDriver.

• Port 49865 is currently being used by some other application running out of your localhost.
• Port 49865 is used by some service running from your localhost.
• Port 49865 haven't been released by a dangling instance of a WebDriver variant e.g. GeckoDriver, ChromeDriver, IEDriverServer or GhostDriver.

解决方案将是以下所有步骤之一或全部:

The solution would be either/all of the following steps :

• 始终在Automation Script的 tearDown() 方法中使用 driver.quit() . 如果WebDriver变体的任何悬空实例，例如GeckoDriver，ChromeDriver，IEDriverServer或GhostDriver存在于您的系统上，杀死是通过编程/手动方式进行的.
• 确保 Port 49865 没有被用在 localhost 之外的其他任何应用程序使用.
• 确保从您的 localhost 运行的某些服务未使用 Port 49865 .
• 在执行Tests之前和之后，使用 CCleaner 工具清除系统上的操作系统杂项.
• 接受 System Reboot
• 如果问题仍然存在，请通过 Revo Uninstaller uninstall Mozilla Firefox Browser 并安装 Mozilla Firefox Browser 的新实例.

• Always use driver.quit() within tearDown() method of your Automation Script. If any dangling instance of WebDriver variant e.g. GeckoDriver, ChromeDriver, IEDriverServer or GhostDriver are present on your system, Kill them programatically/manually.
• Ensure that Port 49865 is not used by any other application running out of your localhost.
• Ensure that Port 49865 is not used by some service running from your localhost.
• Use CCleaner tool before and after executing your Tests to wipe off the OS chores from your system.
• Take a System Reboot
• If the issue still persists, uninstall Mozilla Firefox Browser through Revo Uninstaller and install fresh instance of Mozilla Firefox Browser
