Ruby on Rails Phusion passenger error

Problem

You have already activated base64 0.1.0, but your Gemfile requires base64 0.2.0. Since base64 is a default gem, you can either remove your dependency on it or try updating to a newer version of bundler that supports base64 as a default gem.

If you get such error to start Phusion Passenger, then try following steps

Solution

  1. In your Gemfile lock the base64 to lower version.

    gem "base64", "0.1.1"

    Until they upgrade passenger to support base64 0.2.0, you have to use this solution.

Another Solution

Add passenger_preload_bundler on in your nginx config file.

  passenger_preload_bundler on;

Then restart nginx

  sudo systemctl restart nginx

Refer Nginx#passenger_preload_bundler
