Question

我知道这是一个重复的问题但。StackOverflow是我的最后手段，请帮助我调查这个问题。非常感谢！

所以..我已经在使用网站上可用的Chrome驱动程序的最新版本(2.29(，但是当我启动小型js文件时，我仍会收到通知，导致无法转到特定的URL。

以下是我的js代码：

var webdriver = require('selenium-webdriver');
var driver = new webdriver.Builder().withCapabilities(webdriver.Capabilities.chrome()).build();
driver.get('https://www.google.com');

启动浏览器后，此ERROR也出现在我的nodejs cmd中：

C:UsersJonDesktop>node stockinfo.js --compiled the jsfile
C:UsersJonnode_modulesselenium-webdriverlibpromise.js:2634 --ERROR starts here
        throw error;
        ^

Answer 1

我能够解决我的问题。

我在 Environment Variables上包括了 C:UsersJonnode_moduleschromedriverlibchromedriver as 路径。您可以按照以下步骤访问它：

Control Panel > System > Change Settings > Advanced Tab > Environment Variables > 
System Variable table > Path Variable row > New > Copy paste the location I posted above 
> click OK to close all windows

我还使用了常规 script。请参阅下面：

var webdriver = require('selenium-webdriver'),
    By = webdriver.By,
    until = webdriver.until;
var driver = new webdriver.Builder()
    .forBrowser('chrome')
    .build();
driver.get('http://www.google.com/');

ps 请勿安装selenium-webdriver和chromedriver NPM packages 全球！
