无法为安装在linux redhat服务器上的R studio安装Devtools软件包

ERROR: configuration failed for package ‘RCurl’
* removing ‘/home/xx/R/x86_64-redhat-linux-gnu-library/3.0/RCurl’
Warning in install.packages :
  installation of package ‘RCurl’ had non-zero exit status

ERROR: dependency ‘RCurl’ is not available for package ‘httr’

Warning in install.packages :

我也无法安装RCurl包.我也尝试过安装libcurl库：

sudo yum install libcurl4-openssl-dev
sudo yum install libcurl4-gnutls-dev

但该系统表示没有可用的此类软件包.

有没有其他方法来安装devtools包？或者我该如何解决Rcurl安装问题？
