node.js - 来自 Selenium : UnhandledPromiseRejectionWarning: Error: ECONNREFUSED connect ECONNREFUSED 的错误

Question

我是 node.js 和 Selenium 的新手，所以如果我没有立即提供所需的所有详细信息，请多多包涵。

这是我想在 FF 中运行的非常简单的测试(我在这里发现了很多这样的问题，但它们指的是 Chrome):

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

const builder = new webdriver.Builder();
builder.forBrowser('firefox');
const driver = builder.build();

driver.get('https://google.com');

driver.quit();

这是我不断收到的错误:

(node:3534) UnhandledPromiseRejectionWarning: Error: ECONNREFUSED connect ECONNREFUSED 127.0.0.1:62412 at ClientRequest.

(rejection id: 2) (node:3534) [DEP0018] DeprecationWarning: Unhandled promise rejections are deprecated. In the future, promise rejections that are not handled will terminate the Node.js process with a non-zero exit code.

Selenium 版本:5.6.0

Answer 1

有同样的问题。安装以前版本的 selenium-webdriver 对我有帮助。

npm install selenium-webdriver@3.6.0
