r - 如何解决此网页抓取问题

Question

我正在尝试在 R 中抓取网页。

page <- read_html("https://www.imdb.com/chart/top/") 
header_nodes <- html_nodes(page, css = ".titleColumn a" )
rating_nodes <- html_nodes(page, css = "strong")

我正在尝试提取电影标题和评级，但收到此错误:

Error in inDL(x, as.logical(local), as.logical(now), ...) : ICU init failed: U_FILE_ACCESS_ERROR

尝试使用这个:

library(rvest)
url <- 'https://www.imdb.com/chart/top/'
webpage <- url %>% read_html()

title <- webpage %>% html_nodes('td.titleColumn a') %>% html_text()
title

#[1] "The Shawshank Redemption"                                            
#[2] "The Godfather"                                                       
#[3] "The Godfather: Part II"                                              
#[4] "The Dark Knight"                                                     
#[5] "12 Angry Men"                                                        
#[6] "Schindler's List"                                                    
#[7] "The Lord of the Rings: The Return of the King"             
#...

获取评分:

ratings <- webpage %>% 
            html_nodes('td.ratingColumn strong') %>% 
            html_text() %>% as.numeric()
ratings
