【问题描述】：

我用 chromedriver 手动启动 selenium-hub 和 selenium-node

当我对节点执行测试时，我会看到节点的日志输出

Remote connections are allowed by a whitelist (127.0.0.1).

但测试显示：

        'Driver info: driver.version: unknown' ],
        message: 'unknown error: cannot find Chrome binary' },
    status: 13 }

OsX 的 chrome 驱动程序是独立的。当我将它传递给 Selenium 时，它似乎不起作用。有什么想法吗？

【解决方案1】：

ChromeDriver 希望您将 Chrome 安装在您平台的默认位置。您还可以通过设置以下特殊功能来强制 ChromeDriver 使用自定义位置：

// Selenium Java API
ChromeOptions options = new ChromeOptions();
options.setBinary("/path/to/other/chrome/binary");
