Unable to install curb gem
As I remember it uses curl libs to compile natively
So you will need curl dev libs installedtry installing
sudo apt-get install libcurl4-openssl-dev
or
sudo apt-get install libcurl4-gnutls-dev
On fedora I did sudo yum install curl-devel
and then did gem install curb
and that did the trick for me
In Ubuntu 18.04, using
sudo apt install libcurl4-openssl-dev
and then install curb
gem install curb
