Selenium::WebDriver::Error::WebDriverError: 无法在 45 秒内绑定到锁定端口 7054

                            // TODO Auto-generated catch block
                            e.printStackTrace();
                        }
                      }
                    };
                    new Thread(runner, "TestThread"+i).start();
                    Thread.sleep(5000);
                  }
                  // all threads are waiting on the latch.
    //            latch.countDown();// release the latch

// 现在所有线程都在并发运行。 } 公共静态 void main(String arg[]) 抛出 InterruptedException{ ThreadsRunnable tr = new ThreadsRunnable(); tr.testmain(); } }

下面是我运行的代码来查找端口 7054 是否空闲并且 它始终在控制台上显示为免费。但是，当我通过这个端口时 运行firefox它会出错，端口绑定任何人都可以帮助我 这个。谢谢

我认为您必须将以下主机条目添加到您的主机文件中。

127.0.0.1 localhost

它对我有用
