您的问题是由于 Safari 12 使用了新的 webdriver 协议。这导致了一些不兼容的问题。问题已在此处报告：https://github.com/SeleniumHQ/selenium/issues/6026

您可以将 safaridriver 一个 --legacy 标志传递给 mjdease 在https://github.com/SeleniumHQ/selenium/issues/6026 上发布的旧协议

const webdriver = require('selenium-webdriver');
const safari = require('selenium-webdriver/safari');

new webdriver.Builder()
    .usingServer(await new safari.ServiceBuilder().addArguments('--legacy').build().start())
    .forBrowser('safari')
    .build();
