我有这个示例R刮刀脚本(我不能使用实际网站)：
#!/usr/bin/Rscript
library(RCurl)
library(httr)
library(rvest)
library(lubridate)
library(stringi)
new_files
fun1
paste0("https://example.com", ln)),
config(ssl_verifypeer = FALSE))
if(y == Sys.Date()) {writeBin(fun1$response$content, bn)}
else ("He's dead, Jim")
return(fun1$response$content)
}, links, dates, names)
我正在通过Apache NiFi(ExecuteProcessor处理器)在docker容器中运行此脚本.但是当我设置它运行时,我不断收到此错误：
Process execution failed due to java.io.IOException: Stream closed: java.io.IOException: Stream closed

我应该关闭之前阅读this answer on closing streams.当脚本在我的本地计算机上/在RStudio中正常工作时,我不知道为什么会抛出一个关闭的异常错误.
它一旦在docker容器中执行就会搞砸.与Map函数中的if / else语句有关吗？我不知道 – 或者它与装载lubridate包装有关.
