R/ RStudio - install devtools fails?

Question

I am trying to install devtools in my RStudio. But I get tons of errors:

* installing *source* package ‘curl’ ...
** package ‘curl’ successfully unp         


        

Answer 1

Error Message: Package libcurl was not found in the pkg-config search path. Perhaps you should add the directory containing `libcurl.pc'

Executed this command:

rpm -qa|grep curl

Result

python-pycurl-7.19.0-19.el7.x86_64  
curl-7.29.0-42.el7_4.1.x86_64  
libcurl-7.29.0-42.el7_4.1.x86_64  
-->libcurl-devel-7.29.0-42.el7_4.1.x86_64  <---this entry was missing

Executed this command

yum install libcurl-devel

problem solved.
