Incompatible encoding when requiring a gem

The third line in my ruby script

# encoding: utf-8

require "mail"

results in the following error

/usr/local/share/gems1.9/gems/json-1.8.1/lib/json/pure/parser.rb:242:in `rescue in parse_string': Caught Encoding::CompatibilityError at '[{"content-type":"ap': incompatible encoding regexp match (ASCII-8BIT regexp with UTF-8 string) (JSON::ParserError)

note this error only occurs in production on AWS with Ruby 1.9.3. In development with Ruby 2, it works fine.

Sorry, this is no solution, only an explanation why it works correct with ruby 2.0 but not with 1.9.3:

Since ruby 2.0 all scripts are utf-8-encoded (unless something else is defined)

What is Ruby 2.0.0

[...]

Language core features

[...]

  • The UTF-8 default encoding, which make many magic comments omissible

Source: https://www.ruby-lang.org/en/news/2013/02/24/ruby-2-0-0-p0-is-released/

In Ruby 1.9 UTF-8 is not the default, so there may be a encoding difference between your script in UTF-8 and the script you call.

I solved this issue adding this to my gemfile:

gem 'oj'
gem 'oj_mimic_json'

then run bundle install and try to run server again
