node.js - Selenium 与 PhantomJs 和 NodeJs

Question

我使用 Express 创建了一个项目，现在我尝试使用 Phantomjs 运行 selenium 代码。

我有:

var app = express();

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

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

但是当我尝试运行时出现此错误:

path/node_modules/selenium-webdriver/phantomjs.js:72
    throw Error(
          ^
Error: The PhantomJS executable could not be found on the current PATH. Please download the latest version from http://phantomjs.org/download.html and ensure it can be found on your PATH. For more information, see https://github.com/ariya/phantomjs/wiki

你需要为你的操作系统安装 Phantom JS 包，我使用的是 Ubuntu，所以我这样做了

sudo apt-get install phantomjs

这个错误消失了，如果你已经安装了 phantomjs 包，那么你的路径设置出了问题，请为 phantomjs 设置路径变量
