各位会员:我正在使用RSelenium，并在使用rsDriver时获得以下错误信息:
> rD <- rsDriver(port=free_port(random=TRUE),browser="chrome",chromever="109.0.5414.25",verbose=FALSE)
Could not open chrome browser.
Client error message:
Undefined error in httr call. httr output: Failed to connect to localhost port 795: Connection refused
Check server log for further details.
Warning message:
In rsDriver(port = free_port(random = TRUE), browser = "chrome", :
Could not determine server status.
我已经成功删除了LICENSE。这里提到的Chromedriver文件:https://github.com/ropensci/wdman/issues/31
但是我没有靴子…请帮助…

UPDATE:通过确保删除正确chromever的LICENSE文件，问题得到了解决。在这种情况下，原始发布者删除了许可证。Chromever .
binman/wdman将为每个驱动程序的每个版本下载并创建一个新文件夹。这意味着如果您指定要使用的chromedriver版本，则只会遇到此问题一次。另一方面，默认的行为为binman/wdman采取最新的chromever将意味着一个新的chrome驱动程序的发布可能会破坏你的代码，即使你不使用chrome浏览器在RSelenium
运行selenium(retcommand = T)将告诉您RSelenium如何试图找到您的chromedriver。您可以查看输出以查找chromedriver的文件路径。要寻找的最大标志是R样式"c()"retcommand输出中的向量。如果发生这种情况，您必须删除许可证。chromedriver文件
来自AKshayKulkarni的例子
library(wdman)
selenium(retcommand = T,chromever = '109.0.5414.25')
注意java.exe之后的R向量以">c()开头";这意味着许可证。该文件夹中的Chromedriver需要删除。

原始回答:
library(wdman)
selenium(retcommand = T)
并发布结果?
