硒在Fedora 35中使用铬而不是谷歌铬，我如何设置谷歌铬

Question

首先，对于硒，我不想使用铬(在Linux SO中默认使用铬(，我想使用谷歌铬。其次，当我下载一个带有selenium的文件时，我想以特定的路径下载该文件，例如：src/resources/downloadFiles/，但它不起作用，默认情况下需要/home/myuser/Downloads

这是我的代码：

protected final static Path DOWNLOAD_Path=Paths.get("src/resources/downloadFiles/"(；

Map<String, Object> prefs = new HashMap<String, Object>();
prefs.put("download.default_directory",System.getProperty(DOWNLOAD_PATH.toString()));
ChromeOptions options = new ChromeOptions();
options.setBinary("/home/symlinks/googlechrome/google-chrome");
options.setHeadless(false);
options.setExperimentalOption("prefs", prefs);
webDriver = new ChromeDriver(options);

我试着用一个新的谷歌chrome符号二进制链接路径设置ChromeOptions(或者与谷歌chrome的原始二进制路径一起使用(，但我得到了java.lang.NullPointerException错误：

org.openqa.selenium.SessionNotCreatedException: Could not start a new session. Response code 500. Message: unknown error: Chrome failed to start: exited abnormally.

(未知错误：DevToolsActivePort文件不存在((从chrome location/home/symlinks/googlechrome/启动的进程已不再运行，因此ChromeDriver假设chrome已崩溃。(内部版本信息：版本："4.0.0"，修订版："3a211814679"系统信息：host:"fedora"，ip:"127.0.0.1"，os.name:"Linux"，os.arch:"amd64"，os.version:"5.15.6-200.fc35.x86_64"，java.version:"1.8.0_312"驾驶员信息：org.openqa.selenium.chrome.ChromeDriver命令：[null，newSession｛capabilities=[Cabilities｛browserName:chrome，goog:chromeOptions:{args:[]，binary:/home/symlinks/googlechrome/，extensions:[]，prefs:{download.default_directory:null｝｝]，desiredCabilities=功能｛browserName:chrome，goog:chromeOptions:{args:[]，binary:/home/symlinks/googlechrome/，extensions:[]，prefs:{download.default_directory:null｝｝}]

我发现这是因为我在localhost:中使用的chrome版本

org.openqa.selenium.SessionNotCreatedException: Could not start a new session. Response code 500. Message: session not created: This version of ChromeDriver only supports Chrome version 94

当前浏览器版本为96.0.4664.110，带有二进制路径/home/symlinks/googlechrome/googlechrome
