在Ubuntu上运行chrome驱动程序时,Selenium会出现“未知错误：无法找到Chrome二进制文件”

我试图在最新的ubuntu上使用chrome驱动程序运行selenium [java]测试.[16.04]

我收到以下错误/异常.
作为实验,我用我的原生“helloworldApp”替换了ChromeDriver二进制文件;我发现selenium正在执行我的二进制文件.

我相信在15306端口上打印“启动ChromeDriver 2.27.440175(9bc1d90b8bfa4dd181fbbf769a5eb5e575574320)”来自chrome二进制文件.但为什么硒抱怨它无法获得二进制？

在Windows上一切正常.

请指教.

我发现了问题.在我的Linux系统上,未安装Google Chrome浏览器.

我的印象是ChromeDriver二进制文件中有一个浏览器实现.现在我意识到这是错的,ChromeDriver二进制文件是一个叫做谷歌Chrome的selenium包装器.

我必须说异常消息“selenium.WebDriverException：unkNown error：找不到Chrome二进制文件”令人困惑.如果它告诉“未安装Chrome浏览器”或类似内容,则会更容易.
