I ran into this deploying to a remote box. As suggested in comments, I was able to fix it by opening a console session on the affected box and running:

gem update rails
gem install unf_ext -v '0.0.7.2'

I was having the exact same issue trying to install this specific gem and version as well. Turns out my VPS would run out of RAM while compiling and quit. I just killed off a few processes I could live without for a few minutes and it worked...

I resolved this issue by upgrading bundler. Simply run:

gem install bundler

which fetches the latest bundler. Then, Try running:

bundle install

This error can come across due to various reasons, so it's not easy to tell what might have really caused, preventing you from bundle install, so try the following fixes, if not worked please give more details on errors that appears :) If the error was because of missing gmkdir, then run the following command:

brew install coreutils

If the error was due to missing C++ headers related then run the bellow command:

yum install gcc-c++
