【中文标题】Selenium Firefox 57 无法连接到二进制/本地主机【英文标题】：Selenium Firefox 57 failed to connect to binary / localhost 【发布时间】：2018-05-15 13:22:24 【问题描述】：我使用的是 Firefox 57、geckodriver 0.19.1 和 selenium 3.8.0。 （Java gradle 项目） 顺便说一句：Chrome 做得很好。我的测试有效。
Firefox 启动，但没有任何反应。两三秒后，Intellij 显示异常。
我知道这可能是重复的，但我找不到任何显示每个“组合”的兼容版本的资源。
这是我的异常输出：
org.openqa.selenium.firefox.NotConnectedException: Unable to connect to host 127.0.0.1 on port 7055 after 45000 ms. Firefox console output:

@Test
public void Start() throws URISyntaxException
// Test for each browser definition
for (Browser browser : Browser.values())

configTests.goToLocalPartsfinder();
configTests.quit();
谁能给我一个提示？ 我已经使用过其他 geckodriver 和 selenium 版本。由于IT限制，我不允许更改FF版本...
我也尝试了一堆 FirefoxOptions 都没有成功。
我想知道为什么 chrome 工作正常，但 firefox 什么也没做。
更新：
//build.gradle
dependencies
compile group: 'org.seleniumhq.selenium', name: 'selenium-java', version: '3.8.0'
compile "org.seleniumhq.selenium:selenium-chrome-driver:3.8.0"
compile "org.seleniumhq.selenium:selenium-firefox-driver:3.8.0"
更新2：
更改 build.gradle 添加驱动依赖后，我得到这个异常：

所以我猜还是缺少一个依赖，不是吗？
【问题讨论】：
它是否适用于 selenium3.7.1 或 3.5？
我试过 3.7.1 但没有。我也可以检查3.5。
3.5 没有FirefoxDriver 类，因此我不知道如何使用它。有什么提示吗？
FirefoxDriver 从 2.0 开始存在。但如果它不适用于 3.7.1，那么我们必须考虑另一种方法。
是否存在gradle依赖错误？我将更新我的问题以显示我的 build.gradle 文件
【参考方案1】：
您的问题是由于缺少依赖项引起的
下载所有相关的 Selenium 依赖项。
compile group: 'org.seleniumhq.selenium', name: 'selenium-java', version: '3.8.0'
compile 'org.seleniumhq.selenium:selenium-java:3.8.0'
compile 'org.seleniumhq.selenium:selenium-server:3.8.0'
compile 'org.seleniumhq.selenium:selenium-api:3.8.0'
compile 'org.seleniumhq.selenium:selenium-support:3.8.0'
compile 'org.seleniumhq.selenium:selenium-remote-driver:3.8.0'
compile 'org.seleniumhq.selenium:selenium-chrome-driver:3.8.0'
compile 'org.seleniumhq.selenium:selenium-firefox-driver:3.8.0'

谢谢拉法拉斯科夫斯基。你帮了我很多！以上是关于Selenium Firefox 57 无法连接到二进制/本地主机的主要内容，如果未能解决你的问题，请参考以下文章
