An error occurred while installing curb (0.8.5)

Question

While bundling an old project, this error came up:

Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.

    /home/dd/.rvm/rubies/ruby-2.0.0-p247/bin/ruby extconf.rb 
checking for curl-config... no
checking for main() in -lcurl... no
*** extconf.rb failed ***
Could not create Makefile due to some reason, probably lack of necessary
libraries and/or headers.  Check the mkmf.log file for more details.  You may
need configuration options.

Provided configuration options:

    --without-opt-dir
    --with-opt-include
    --without-opt-include=${opt-dir}/include
    --with-opt-lib

  Try passing --with-curl-dir or --with-curl-lib and --with-curl-include
  options to extconf.

Answer 1

On CentOS

sudo yum install libcurl-devel

Answer 2

I found the solution here

sudo apt-get install libcurl3-dev

Answer 3

It says it can't install curb gem. Go to curb homepage and check installation section:

On Ubuntu, the dependencies can be satisfied by installing the following packages:

$ sudo apt-get install libcurl3 libcurl3-gnutls libcurl4-openssl-dev

On RedHat:

$ sudo yum install ruby-devel libcurl-devel openssl-devel
