更新：自RSelenium 1.7.9起，所述问题已消失。
我知道，有人问过类似的问题，但他们的解决方案对我不起作用
摘要：我想通过R的软件包RSelenium在Linux下打开一个Selenium服务器和一个客户端。但是，尽管我尝试了文档中描述的两种方法(同时我想避免docker(它不能可靠地工作。
我的系统：Linux 5.19，R 4.2.1，R硒1.7.7、硒服务器-标准-4.0.0-α-2，变色龙104.0.5112.79-2.1、壁虎0.31.0(binman(，我已经测试了OpenJDK 11和OpenJDK 18(目前(
I。硒通过JAVA
在Linux控制台中

在R I类型中：
remDr <- remoteDriver(remoteServerAddr = "localhost", port = 4444L, browserName = "chrome", version = "104.0.5112.79")
并在Linux控制台中获得输出：

"javascriptEnabled": true,

Chrome浏览器打开，R控制台给了我死亡之吻：
Error in checkError(res) :
Undefined error in httr call. httr output: Failed initialization
这意味着，我不能使用R-控制台进行导航。另一种方法：
II。硒通过硒：：rsDriver
rD <- RSelenium::rsDriver(browser="firefox", port = 4567L, verbose = FALSE)
大部分收益率(打开浏览器窗口(
Could not open firefox browser.
Client error message:
Undefined error in httr call. httr output: Failed initialization
Check server log for further details.
但是：完全相同的代码可以工作！随机或者在长时间打开R之后？！？无尽的测试？！？突然间，我得到了几个正在运行的服务器/客户端连接，包括网页上的导航：
$acceptInsecureCerts
[1] FALSE
$browserName
[1] "firefox"
$browserVersion
[1] "103.0.2"
$`moz:accessibilityChecks`
[1] FALSE
$`moz:buildID`
[1] "20220815180539"
$`moz:geckodriverVersion`
[1] "0.31.0"
etc.pp.
但最晚当我重新启动电脑时，我再次收到同样的错误消息。它也可以通过中的RSelenium在删除和重新安装四个驱动程序后工作/本地/共享。或者，当我再次尝试同样的方法时，它根本没有。我从来没有遇到过这种随机性的问题。它从哪里来？
PS：服务器日志，如果它不起作用，可以有额外的行，我添加了：
> rD$server$log()
$stderr

[27] "Missing chrome or resource URL: resource://gre/modules/UpdateListener.sys.mjs"

也许您可以尝试以下依赖Docker的方法：
library(RSelenium)
url <- "https://www.hubs.com/3d-printing/#/?place=New%20York&latitude=40.7144&longitude=-74.006&distanceLimit=250&distanceUnit=miles&shipsToCountry=US&shipsToState=NY"
shell('docker run -d -p 4445:4444 selenium/standalone-firefox')
remDr <- remoteDriver(remoteServerAddr = "localhost", port = 4445L, browserName = "firefox")
remDr$open()
remDr$navigate(url)
remDr$getPageSource()[[1]]
