.net 5 Selenium webdriver没有在docker容器错误中工作:没有这样的文件或目录

Question

我对使用.net的selenium有一个问题，需要您的帮助。

我正在使用.net 5，并试图在Linux上运行Selenium，并获得"System.ComponentModel.Win32Exception No这样的文件或目录“错误。我以为chromedriver文件不存在。但是我已经检查了路径是正确的，甚至我把发色器放在usr/local/bin，app/文件夹中。

当我没有码头的时候它就能工作了。

我的代码：

...
using OpenQA.Selenium;
using OpenQA.Selenium.Chrome;
....
var chromeOptions = new ChromeOptions();
chromeOptions.AddArgument("headless");
chromeOptions.AddArgument("no-sandbox");
chromeOptions.PageLoadStrategy = PageLoadStrategy.Eager;

// var driver = new ChromeDriver(chromeOptions);
// var driver = new ChromeDriver("/usr/local/bin/",chromeOptions); 
var driver = new ChromeDriver(AppDomain.CurrentDomain.BaseDirectory, chromeOptions);

错误：

An unhandled exception has occurred while executing the request.

    ln -fs /opt/chromedriver-$CHROMEDRIVER_VERSION/chromedriver /usr/local/bin/chromedriver && \

一揽子信息：

.Net 5
Selenium.WebDriver --version 4.0.1
ChromeDriver version 94.0.4606.41 
Operating System: Ubuntu 20.

我使用的是远程驱动程序，而不是铬文件。
