系统： Linux - CentOS 6.5
R 版本： 3.2.3（64 位）
我在这里暴露了同样的错误：
>devtools::install_github("pauca/rrdkit/rrdkit")
Downloading GitHub repo pauca/rrdkit@master
from URL https://api.github.com/repos/pauca/rrdkit/zipball/master
Error in curl::curl_fetch_memory(url, handle = handle) :

我测试了 maddy2u 的解决方案，但它在我的工作站上无法使用options(download.file.method = "wget")or options(download.file.method = "libcurl")。我尝试了很多东西，但我没有解决这个问题的想法。
欢迎任何帮助，并提前致谢。
