Question

我正在遵循本指南：http://webdriver.io/guide.html 和我使用的 firefox 版本 62.0

我遵循了以下步骤：

我下载了最新的 selenium-standalone-server 版本 3.14。
我已经下载了最新的 gecko 驱动程序版本 0.22.0 并将其解压到项目文件夹中
运行 selenium 独立版本使用命令 java -jar -Dwebdriver.gecko.driver=./geckodriver selenium-server-standalone-3.5.3.jar
然后运行命令npm install webdriverio
使用代码

var webdriverio = require('webdriverio');
var options = {
    desiredCapabilities: {
        browserName: 'firefox'
    }
};

webdriverio
    .remote(options)
    .init()
    .url('http://www.google.com')
    .getTitle().then(function(title) {
        console.log('Title was: ' + title);
    })
    .end()
    .catch(function(err) {
        console.log(err);
    });

节点test.js

而不是获取输出 "Title was: Google" 我收到错误

任何人都可以指导如何解决此错误吗？？

Answer 1

好像有点乱。您提到过：

已下载最新的 selenium-standalone-server 版本 3.14

命令

java -jar -Dwebdriver.gecko.driver=./geckodriver selenium-server-standalone-3.5.3.jar
                            observe the versioning ^^^ info

日志消息反映：
```
Build info: version: \'3.4.0\'
```

解决方案

将 Selenium 升级到当前级别 Version 3.14.0。
将 GeckoDriver 升级到 GeckoDriver v0.22.0 级别。
将 Firefox 版本升级到 Firefox v62.0 级别。
执行你的测试
