将require（'chromedriver）.path直接传递给selenium-webdriver [英] Passing require('chromedriver).path directly to selenium-webdriver

问题描述

tl; dr： 有没有人知道如何在不设置PATH环境变量的情况下将chromedriver的路径传递给代码中的selenium-webdriver？

我正在尝试使用带有chrome的selenium-webdriver，但更愿意不在物理上安装chromedriver并操纵路径。我有以下代码：

I'm attempting to use selenium-webdriver with chrome, but would prefer to not physically install chromedriver and manipulate the path. I have the following code:

var webdriver = require('selenium-webdriver');
var driver = new webdriver.Builder().
    withCapabilities(webdriver.Capabilities.chrome()).
    build();

如果路径中没有设置chromedriver，则会抛出错误：

Without chromedriver set in the path, this throws the error:

Error: The ChromeDriver could not be found on the current PATH. Please download the latest 
version of the ChromeDriver from http://chromedriver.storage.googleapis.com/index.html and 
ensure it can be found on your PATH.

我不想设置我的路径，所以我从npm安装了chromedriver并添加了到我的package.json：

I'd prefer not have to setup my path, so I've installed chromedriver from npm and added to my package.json:

"scripts": {
    "preinstall-chromedriver": "npm install",
    "install-chromedriver": "node node_modules/chromedriver/install.js",
    "pretest_e2e": "npm run install-chromedriver",
    "test_e2e": "node release/test/rune2e.js"
},

现在我安装了chromedriver并且可以获得路径使用 require（'chromedriver'）。path ，但我无法将其传递给selenium-webdriver。有人知道吗？

Now I have chromedriver installed and can get the path with require('chromedriver').path, but I have no way of passing this to the selenium-webdriver. Anyone know?

推荐答案

你需要创建&设置您自己的默认Chrome服务。

You need to create & set your own default chrome service.

var webdriver = require('selenium-webdriver');
var chrome = require('selenium-webdriver/chrome');
var path = require('chromedriver').path;

var service = new chrome.ServiceBuilder(path).build();
chrome.setDefaultService(service);

var driver = new webdriver.Builder()
    .withCapabilities(webdriver.Capabilities.chrome())
    .build();
