Selenium: The ChromeDriver could not be found on the current PATH

安装官网提示的安装步骤进行安装并开始启动时报如下错误
The ChromeDriver could not be found on the current PATH. Please download the latest version of the ChromeDriver fromhttp://chromedriver.storage.googleapis.com/index.html and ensure it can be found on your PATH.

当时反复确认自己的代码和环境变量配置无误后，就直接看源码了

代码如下

const { Builder } = require('selenium-webdriver');
const { suite } = require('selenium-webdriver/testing');
const chrome = require('selenium-webdriver/chrome');

suite(function(env) {
    describe('Open Chrome', function() {
        let driver;

        before(async function() {
            let options = new chrome.Options();
            driver = await new Builder()
                .setChromeOptions(options)
                .forBrowser('chrome')
                .build();
        });

        // after(() => driver.quit());

        it('Basic Chrome test', async function() {
            await driver.get('https://www.baidu.com');
        });

    });
});

环境变量如下

在源码中找到 locateSynchronously()函数并进行debug发现原来是 环境变量未更新 所以解决方案时重启电脑或者重启node即可
