Question

我试图在RStudio中使用RSelenium搜索美国人口普查数据，但我无法使用Chrome浏览器导航到某个网址。

我已经运行了Selenium Standalone Server，并且在系统设置中将chrome驱动程序设置为环境变量。

作为最低工作示例，我能够实现以下命令：

> library(RSelenium)
> remDr <- remoteDriver(browserName = "chrome")
> remDr$open()

运行最后一个命令会给我以下输出：

[1] "Connecting to remote server"
$applicationCacheEnabled
[1] FALSE

$rotatable
[1] FALSE

$chrome
$chrome$userDataDir
[1] "C:\\Users\\rchoksi\\AppData\\Local\\Temp\\scoped_dir5908_26290"


$takesHeapSnapshot
[1] TRUE

$databaseEnabled
[1] FALSE

$handlesAlerts
[1] TRUE

$version
[1] "61.0.3163.79"

$platform
[1] "Windows NT"

$browserConnectionEnabled
[1] FALSE

$nativeEvents
[1] TRUE

$acceptSslCerts
[1] TRUE

$locationContextEnabled
[1] TRUE

$webStorageEnabled
[1] TRUE

$browserName
[1] "chrome"

$takesScreenshot
[1] TRUE

$javascriptEnabled
[1] TRUE

$cssSelectorsEnabled
[1] TRUE

$id
[1] "f28c4373e6063f797904f3e4a890d02b"

我相信＆＃39; browserConnectionEnabled＆＃39;设置为FALSE的属性会产生问题，但我可能错了。

运行以下命令时，出现如下错误。

> remDr$navigate("https://factfinder.census.gov/faces/nav/jsf/pages/index.xhtml")
