【问题描述】：
我从 dockerhub 下载了 rocker/tidyverse。我尝试安装一个软件包并受到欢迎：
网址“https://cran.rstudio.com/src/contrib/PACKAGES.rds”：状态为“无法连接到服务器”
登录 rstudio 后，我尝试执行此处显示的所有命令： https://support.rstudio.com/hc/en-us/articles/226914208-Installing-packages-on-RStudio-Connect-from-behind-a-proxy
虽然我仍然遇到同样的错误。如何设置代理以安装软件包？
更新：
尝试在 rstudio 中运行时出现以下错误：
library(httr)
set_config(use_proxy(url="my.proxy.url", port=XXX, username="my_user_name", password="my_password"))
set_config( config( ssl_verifypeer = 0L ) )
安装后：
install.packages("fpc", dependencies = TRUE)
