[R] curl package new_handle() error on Centos7

[WU Degang]

Hi everyone,

I am using R-3.6.0 on CentOS 7.7. I got the following error message when I typed �curl::curl_download(url,tempfile())�:

Error in new_handle() : An unknown option was passed in to libcurl

Because of this error, I cannot use devtools::install_github. The version of curl is the one that comes with CentOS 7.7: curl 7.29.0. My R session info:

How can I deal with this error?
