拒绝连接！ selenium服务器是否已启动？

我正在使用Jenkins进行selenium nightwatch测试.

当我运行测试时,我收到以下错误：

Connection refused! Is selenium server started?

我的nightwatch.json文件中有以下配置：

"selenium": {
        "start_process": true,
        "server_path": "lib/selenium-server-standalone-2.52.0.jar",
        "log_path": "",
        "host": "127.0.0.1",
        "port": 4444,
        "cli_args": {
            "webdriver.chrome.driver": "lib/chromedriver",
            "webdriver.ie.driver": "lib/IEDriverServer_x64_2.52.2.exe",
            "trustAllSSLCertificates": true
        }

我猜jenkins试图连接到PORT,但无法这样做.有人可以帮忙吗？

确保browserName正确无误.

"desiredCapabilities": {
    "browserName": "internet explorer",
    "javascriptEnabled": true,
    "acceptSslCerts": true
}

browserName：“Internet explorer”而不是“ie”你也错过了webdriver.chrome.driver中的“.exe”
