I have tried installing

rvm pkg install readline
rvm pkg install iconv
rvm install 1.8.7
rvm use 1.8.7 

Even tried Why does installing Nokogiri on Mac OS fail with libiconv is missing?.

Nothing works. Please help!

Thanks!

It shows that the iconv not exist but the iconv has installed in my production env.

root@AY130/current# iconv --version
iconv (Ubuntu EGLIBC 2.15-0ubuntu10.4) 2.15

To resolve it, add this in your Gemfile:

gem "iconv", "~> 1.0.3"

Then run bundle install.

Note: iconv has been deprecated for a while. It is replaced by (builtin) String#encode
