删除LICENSE.chromedriver后RSelenium的rsDriver仍报错求助

我在使用RSelenium调用rsDriver()时遇到无法连接Chrome的问题，执行以下代码：

rD <- rsDriver(port=free_port(random=TRUE),browser="chrome",chromever="109.0.5414.25",verbose=FALSE)

得到错误：

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.

我已经尝试删除LICENSE.chromedriver文件，但问题仍未解决。

解决方案 #

从输出可以看到，指定chromever="109.0.5414.25"时，生成的Selenium启动命令重复设置了-Dwebdriver.chrome.driver，同时指向了chromedriver.exe和LICENSE.chromedriver文件，这会导致驱动加载失败。按以下步骤解决：

1. 清理缓存目录：删除C:\Users\Administrator\AppData\Local\binman\binman_chromedriver\win32\109.0.5414.25整个文件夹，彻底清除损坏的驱动文件。
2. 安装匹配的ChromeDriver：本地Chrome版本是109.0.5414.75，选择列表中最接近的109.0.5414.74版本安装：

   wdman::chrome_install("109.0.5414.74")
   

3. 调用rsDriver时指定正确版本：

   rD <- rsDriver(port=free_port(random=TRUE), browser="chrome", chromever="109.0.5414.74", verbose=FALSE)
   

4. 更新Selenium Server：当前使用的是老旧的4.0.0-alpha-2版本，建议更新到稳定版：

   wdman::selenium_install(version = "4.8.0") # 或最新稳定版本号
