OpenQA.Selenium.WebDriverException:未知错误:Chrome无法启动:在Linux上通过Selenium start执行测试时异常退出 [英] OpenQA.Selenium.WebDriverException: unknown error: Chrome failed to start: exited abnormally while executing tests through Selenium start on linux

问题描述

我使用.NetCore创建了一个使用 Selenium 的应用程序，以便在Linux上使用它，实际上这是我的代码实现:

I created an application that use Selenium using .NetCore for use it on Linux, actually this is my code implementation:

public class Program 
{
    public static async Task Main(string[] args)
    {
        //Settings for chrome
        var chromeOpts = new ChromeOptions();
        chromeOpts.AddArgument("headless");
        chromeOpts.AddArgument("no-sandbox");

        //Get assembly path where chrome driver is located
        string codeBase = Assembly.GetExecutingAssembly().CodeBase;
        UriBuilder uri = new UriBuilder(codeBase);
        string path = Uri.UnescapeDataString(uri.Path);
        path = Path.GetDirectoryName(path);

        var driver = new ChromeDriver(path, chromeOpts, TimeSpan.FromSeconds(180));
    }
}

如您所见，我正在使用Chrome作为驱动程序，我下载了它在这里，我还将驱动程序添加到了程序集的文件夹中，这样ChromeDriver便知道了在哪里进行搜索.

as you can see I am using as driver Chrome, I downloaded it here, I also added the driver inside the folder of the assembly, in this way the ChromeDriver knows already where to search it.

在linux上，我使用 chmod -R 777 更改了文件夹权限，但是当我运行Dotnet应用程序时，我得到了以下提示:

On linux I changed the folder permission using chmod -R 777, but when I run my Dotnet application I get this:

似乎 Selenium 无法启动该应用程序. 查看异常，我得到:

Seems that Selenium cannot start the application. Looking at the Exception I get:

找不到Chrome二进制文件

Cannot find Chrome binary

不幸的是，我没有在网络上找到任何类似的东西，有人可以帮助我吗?

Unfortunately I didn't find anything similar on the web, someone could help me?

谢谢.

更新

我刚刚在Linux机器上重新安装了Chrome，现在上面的错误消失了，但是现在还有另一个问题，实际上我得到了这个错误:

I Just reinstalled Chrome on my linux machine and now the error above went away, but there is another problem now, infact I get this error:

OpenQA.Selenium.WebDriverException: unknown error: Chrome failed to start: exited abnormally  (Driver info: chromedriver=2.9.248304,platform=Linux 4.4.0-130-generic x86_64)

推荐答案

此错误消息...

OpenQA.Selenium.WebDriverException: unknown error: Chrome failed to start: exited abnormally

...表示 ChromeDriver 无法启动/产生新的 WebBrowser ，即 Chrome浏览器会话.

...implies that the ChromeDriver was unable to initiate/spawn a new WebBrowser i.e. Chrome Browser session.

您的主要问题是所使用的二进制文件版本之间的不兼容性:

Your main issue is the incompatibility between the version of the binaries you are using as follows:

• 您使用的是 chromedriver = 2.9 ，它非常古老.

• You are using chromedriver=2.9 which is pretty ancient.

因此 ChromeDriver 版本( v2.33 )与最新的 Chrome浏览器版本( vVersion 68.0 )

So there is a clear mismatch between the ChromeDriver version (v2.33) and the recent Chrome Browser version (vVersion 68.0)

• 将 ChromeDriver 升级到当前的 ChromeDriver v2.41 级别.
• 将 Chrome 版本保持在 Chrome v67-69 级别之间. (根据ChromeDriver v2.41发行说明)
通过 IDE
• 清理您的项目工作区和重建您的项目，并且仅具有必需的依赖项.
• 如果您的基本 Web客户端版本太旧，请通过来卸载. Revo Uninstaller 并安装最新版本的 Web客户端 GA和发行版.
• 执行您的@Test.

• Upgrade ChromeDriver to current ChromeDriver v2.41 level.
• Keep Chrome version between Chrome v67-69 levels. (as per ChromeDriver v2.41 release notes)
• Clean your Project Workspace through your IDE and Rebuild your project with required dependencies only.
• If your base Web Client version is too old, then uninstall it through Revo Uninstaller and install a recent GA and released version of Web Client.
• Execute your @Test.
