使用install_github时出错| devtools | 超时问题

Question

当我尝试使用devtools从git-hub下载并安装软件包时，我遇到了这个问题。

R版本：3.1.3（64位）

> install_github("hadley/httr")
Downloading github repo hadley/httr@master
Error in curl::curl_fetch_memory(url, handle = handle) : 
  Timeout was reached

> traceback()
13: .Call(R_curl_fetch_memory, url, handle)
12: curl::curl_fetch_memory(url, handle = handle)
11: request_fetch.write_memory(req$output, req$url, handle)
10: request_fetch(req$output, req$url, handle)
9: request_perform(req, hu$handle$handle)
8: httr::HEAD(src_submodules, , auth)
7: github_has_remotes(x, auth)
6: remote_download.github_remote(remote, quiet = quiet)
5: remote_download(remote, quiet = quiet)
4: FUN(X[[1L]], ...)
3: vapply(remotes, install_remote, ..., FUN.VALUE = logical(1))
2: install_remotes(remotes, ...)
1: install_github("hadley/httr")

编辑：

我正在使用Revolution R Enterprise 7.4和Rstudio客户端。

问题得到解决。 在install_github命令之前设置此选项时，问题已解决。

Answer 2

这对我有用：

library(httr)
with_config(use_proxy(...), install_github(...))

要么

library(httr)
set_config(use_proxy(url = "******", port = ****))
devtools::install_github("username/packagename")
