RSelenium不連接

Question

我試圖用RSelenium封裝連接了一個問題：

> checkForServer() 
> startServer() 
$stop 
function() 
{ 
    tools::pskill(selPID) 
} 
<environment: 0x00000000039724d8> 

$getPID 
function() 
{ 
    return(selPID) 
} 
<environment: 0x00000000039724d8> 

> remDr <- remoteDriver() 
> remDr$open() 
[1] "Connecting to remote server" 
Error: Summary: UnknownError 
    Detail: An unknown server-side error occurred while processing the command. 
    class: org.openqa.selenium.WebDriverException 

我已經在我的電腦配置的Java，但RSelenium仍然失敗。而且我在這個網頁上看過很多帖子，但我仍然沒有解決方案。我能做什麼？我的電腦是帶有Windows 10 Home Single的華碩X555LB。我附上會議信息：

我希望你的幫助。

更新：

Answer 1

可以在安裝seleniumPipes和檢查任何錯誤的輸出可能會給：

devtools::install_github("johndharrison/seleniumPipes") 
selServ <- RSelenium::startServer() 
library(seleniumPipes) 
remDr <- remoteDr() 
remDr %>% go("http://www.google.com/ncr") 
remDr %>% deleteSession() 
selServ$stop() 

更新：

從seleniumPipes你的輸出表明硒司機版本是2.53.1。該消息還表示無法找到Firefox二進制文件。您可以使用 startServer（需要開發版本）將firefox二進制路徑作爲JVM的參數。

selServ <- RSelenium::startServer(javaargs = c("-Dwebdriver.firefox.bin='C:\\YOURDIRPATH\\firefox.exe'")) 

或者手動啓動硒二進制：

java -Dwebdriver.firefox.bin="C:\YOURDIRPATH\firefox.exe" -jar "selenium-server-standalone.jar"
