org.openqa.selenium.SessionNotCreatedException:无法创建新的会话

Question

当我运行appium测试用例时，我得到了这个错误，下面是我的程序

import java.net.MalformedURLException;
import java.net.URL;
import org.openqa.selenium.By;
import org.openqa.selenium.Platform;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.remote.BrowserType;
import org.openqa.selenium.remote.CapabilityType;
import org.openqa.selenium.remote.DesiredCapabilities;
import org.testng.annotations.Test;
import io.appium.java_client.android.AndroidDriver;
import io.appium.java_client.remote.MobileCapabilityType;

public class Sample {

@Test
public void m1() throws MalformedURLException, InterruptedException{
    // Create object of desired class and specify android platform
    DesiredCapabilities capabilities = DesiredCapabilities.android();

    // set the capabilities to execute in chrome browser
    capabilities.setCapability(MobileCapabilityType.BROWSER_NAME, BrowserType.CHROME);

    // set capability to execute our test in Android platform
    capabilities.setCapability(CapabilityType.PLATFORM, Platform.ANDROID);

    // need to define platform name
    capabilities.setCapability(MobileCapabilityType.PLATFORM_NAME, "Android");

    // set device name
    capabilities.setCapability(MobileCapabilityType.DEVICE_NAME, "My Mobile");

    // set version
    capabilities.setCapability(CapabilityType.VERSION, "6.0");

    // create object of url and assign appium server address
    URL url = new URL("http://127.0.0.1:4723/wd/hub");

    WebDriver driver = new AndroidDriver<>(url, capabilities);
    driver.get("http://www.facebook.com");
    System.out.println(driver.getTitle());
    driver.findElement(By.name("email")).sendKeys("suhailxxxxx@gmail.com");
    driver.findElement(By.name("pass")).sendKeys("xxxxxxxxx");
    Thread.sleep(10000);
}

}

下面是我在日食中遇到的问题

Answer 1

更新你的appium服务器，节点JS和npm，然后尝试它。它为我工作，我在更新到1.7.1版本后使用appium服务器1.4，它工作了。

Answer 2

请检查你的APPIUM服务器，它是否已启动。

Answer 3

能否关闭当前appium会话，然后再试一次。如果您仍然看到错误，您的appium版本是什么？
