Lately when starting Unicorn instances, I've encountered following issue:
$ bundle exec unicorn_rails -c config/unicorn.rb -E production -D /gems_path/lib/bundler.rb:294:in `block in load_gemspec_uncached': invalid byte sequence in US-ASCII (ArgumentError) from /gems_path/lib/bundler.rb:291:in `chdir' from /gems_path/lib/bundler.rb:291:in `load_gemspec_uncached' from /gems_path/lib/bundler.rb:282:in `load_gemspec' from /gems_path/lib/bundler/source.rb:411:in `block in load_spec_files' from /gems_path/lib/bundler/source.rb:410:in `each' from /gems_path/lib/bundler/source.rb:410:in `load_spec_files' from /gems_path/lib/bundler/source.rb:799:in `load_spec_files' from /gems_path/lib/bundler/source.rb:381:in `local_specs' from /gems_path/lib/bundler/source.rb:774:in `specs' from /gems_path/lib/bundler/lazy_specification.rb:53:in `__materialize__' from /gems_path/lib/bundler/spec_set.rb:86:in `block in materialize' from /gems_path/lib/bundler/spec_set.rb:83:in `map!' from /gems_path/lib/bundler/spec_set.rb:83:in `materialize' from /gems_path/lib/bundler/definition.rb:113:in `specs' from /gems_path/lib/bundler/definition.rb:158:in `specs_for' from /gems_path/lib/bundler/definition.rb:147:in `requested_specs' from /gems_path/lib/bundler/environment.rb:23:in `requested_specs' from /gems_path/lib/bundler/runtime.rb:11:in `setup' from /gems_path/lib/bundler.rb:116:in `setup' from /gems_path/lib/bundler/setup.rb:7:in `<top (required)>' from /gems_path/rubygems/custom_require.rb:36:in `require' from /gems_path/rubygems/custom_require.rb:36:in `require'
There are two ways to fix this. You can export language settings to your shell:
export LANGUAGE=en_US.UTF-8 export LANG=en_US.UTF-8 export LC_ALL=en_US.UTF-8
or you can put this into your Gemfile:
if RUBY_VERSION =~ /1.9/ Encoding.default_external = Encoding::UTF_8 Encoding.default_internal = Encoding::UTF_8 end
Both methods should work.
