Question

这是我的文件

需要“ selenium-webdriver”

driver = Selenium :: WebDriver.for：chrome

我的路径c:\windows\system32\chromedriver.exe中有铬硒驱动程序文件，我从https://chromedriver.storage.googleapis.com/index.html?path=73.0.3683.20/获得了文件

这种事情以前对我有用。

C:\blah>

我认为也许由于某种原因突然需要写入该文件，并且位于c:\windows\system32中的文件对此进行了限制，因此我将其移至c：\ abc并将其添加到路径中，但是还是一样的错误。

错误提到端口9514。我没有监听端口9514

C：\ Users \ user> netstat -aon | grep 9514

C：\ Users \ user>

我还能够在端口9514上启动服务器并在其上进行监听（已通过nc -l 9514和netstat -aon | grep 9514测试），因此服务器在端口9514上监听没有问题。 / p>

我尝试了gem install selenium-webdriver，但还是同样的问题

我有Chrome版本72，根据http://chromedriver.chromium.org/downloads，兼容版本为ChromeDriver 2.46或ChromeDriver 72.0.3626.69，但两者均给出相同的错误。

我尝试用创建一个Gemfile

source 'https://rubygems.org'

gem 'selenium-webdriver'

然后做bundle install

但ruby aaa.rb仍然出现相同的错误

Answer 1

我在评论中提到

我可能会尝试重置tcp / ip堆栈或某些内容，因为我注意到我无法 ping 127.0.0.1 .. nc已绑定到0.0.0.0，我尚未测试过绑定到 127.0.0.1 ..将对此进行调查

某些情况下肯定无法ping 127.0.0.1是一个很好的主意。如此处所述，我尝试重置tcp / ip堆栈https://superuser.com/questions/29720/general-failure-when-pinging-to-127-0-0-1

运行命令netsh int ip reset然后重新启动，我发现然后可以ping 127.0.0.1，并且不再出现该错误。

试图在红宝石“ 127.0.0.1”端口9514中运行硒（Errno :: EADDRNOTAVAIL）
