Error while bundle install for idn-ruby

On a Mac, you can do:

$ brew install libidn

As per the error show in logs ERROR: could not find idn library!. idn library is required to install twitter text. Try to install that first and then install the gem. Try with

sudo apt-get install libldap2-dev
sudo apt-get install libidn11-dev

Hope this solves your problem.

For mac:

brew install libidn

If you're using Mac OS, then here's how to install libidn:

$ brew install libidn
