我正在尝试使用命令
从R控制台打开chrome> remDr <- remoteDriver(remoteServerAddr = "localhost" , port = 4444 , browserName = "chrome")
> remDr$open()
这些版本都是最新的。 铬 - 55 chromedriver - 2.27 selenium独立服务器 - 3.0.1
我可以使用以下错误消息连接到远程服务器，但它无法打开浏览器。
$message
[1] "unknown error: Chrome failed to start: exited abnormally\n (Driver info: chromedriver=2.27.440175 (9bc1d90b8bfa4dd181fbbf769a5eb5e575574320),platform=Linux 3.19.0-64-generic x86_64)"
但是当我尝试导航时，它会抛出以下错误，

请有人在这里帮助我。 感谢
答案 0 :(得分：1)
chrome / chromedriver / selenium服务器似乎存在问题。您需要详细记录以更详细地检查：
library(wdman)
library(RSelenium)
selServ <- selenium(jvmargs = c("-Dwebdriver.chrome.verboseLogging=true"))
remDr <- remoteDriver(port = 4567L, browserName = "chrome")
remDr$open()
selServ$log()
或者如果您更喜欢在终端中单独运行，请启动selenium服务器，如下所示：
java -Dwebdriver.chrome.verboseLogging=true -Dwebdriver.chrome.driver=/home/hdpusr/ChromeDriver/chromedriver -jar selenium-server-standalone-3.0.1.jar -port 4444
如果问题不明显，您可以向https://bugs.chromium.org/p/chromedriver/issues/list提交问题。
