How to update RCurl and curl to the version on the host machine?
问题 Initially I was trying to use devtools::install_github("EdwinTh/padr") where I got the following error: Error in curl::new_handle() : An unknown option was passed in to libcurl After some time I found out that devtools uses curl/RCurl which wraps the current version of curl on the host machine. The host(Ubuntu 14.04.5 LTS) machine version of curl is: 1$ curl -V curl 7.61.0 (x86_64-pc-linux-gnu) libcurl/7.61.0 OpenSSL/1.0.1f zlib/1.2.8 libssh2/1.8.0 librtmp/2.3 where curl is located in: 12$
