install curl and readr on R

Question

Greeting dear community. I try to install readr but it gives me an error because of there is no curl. I then try to install curl and it asks for another dependency. I verify that in the command prompt but it looks like its already installed. Any idea ? See blow: Many Thanks

Try to install readr:

Install curl in terminal:

[oracle@localhost data]$ sudo yum -y install curl Loaded plugins: langpacks Package curl-7.29.0-19.el7.x86_64 already installed and latest version Nothing to do [oracle@localhost data]$ sudo yum -y install libcurl Loaded plugins: langpacks Package libcurl-7.29.0-19.el7.x86_64 already installed and latest version Nothing to do 

It looks like libcurl is there ?

[oracle@localhost data]$ locate libcurl  /home/oracle/anaconda/lib/libcurl.a /home/oracle/anaconda/lib/libcurl.la /home/oracle/anaconda/lib/libcurl.so /home/oracle/anaconda/lib/libcurl.so.4 /home/oracle/anaconda/lib/libcurl.so.4.3.0 /home/oracle/anaconda/lib/pkgconfig/libcurl.pc /home/oracle/anaconda/pkgs/curl-7.38.0-0/lib/libcurl.a /home/oracle/anaconda/pkgs/curl-7.38.0-0/lib/libcurl.la /home/oracle/anaconda/pkgs/curl-7.38.0-0/lib/libcurl.so /home/oracle/anaconda/pkgs/curl-7.38.0-0/lib/libcurl.so.4 /home/oracle/anaconda/pkgs/curl-7.38.0-0/lib/libcurl.so.4.3.0 /home/oracle/anaconda/pkgs/curl-7.38.0-0/lib/pkgconfig/libcurl.pc /usr/lib64/libcurl.so.4 /usr/lib64/libcurl.so.4.3.0 

So does the curl-config is there..

[oracle@localhost data]$ locate curl-config /home/oracle/anaconda/bin/curl-config /home/oracle/anaconda/pkgs/curl-7.38.0-0/bin/curl-config [oracle@localhost data]$

I solved the problem on Ubuntu 14.04 by using this command

sudo apt-get install libcurl4-openssl-dev

Future users can search for the latest libcurl using:
apt-cache search libcurl
