ruby-on-rails-3 - 尝试使用 phusion 乘客启动 rails 应用程序时，US-ASCII 中的字节序列无效

Question

我正在尝试使用 Phusion 乘客和 RVM 在 Ubuntu 生产服务器上部署 Rails 3 应用程序。我已成功安装 Phusion 乘客，但在浏览器上访问服务器时出现以下错误:

Ruby (Rack) application could not be started

These are the possible causes:

There may be a syntax error in the application's code. Please check for such errors and fix them.

A required library may not installed. Please install all libraries that this application requires.

The application may not be properly configured. Please check whether all configuration files are written correctly, fix any incorrect configurations, and restart this application.

A service that the application relies on (such as the database server or the Ferret search engine server) may not have been started. Please start that service.

有关错误的更多信息可能已写入应用程序的日志文件。请检查它以分析问题。

错误信息:
US-ASCII 中的无效字节序列

异常类:
参数错误

据我了解，在启动应用程序时会调用 Bundler.setup() 并偶然发现一个非 ascii 字符。这是有道理的，因为该应用程序适用于法国网站，但我确保添加 # -*- encoding : utf-8 -*-在每个包含非 ascii 字符的源文件之上。

这是我的 Gemfile :

# -*- encoding : utf-8 -*-
source 'https://rubygems.org'

gem 'rails', '3.2.7'
gem "will_paginate", :git => "https://github.com/p7r/will_paginate.git", :branch => "rails3"
gem "lorem"
gem 'paperclip'
gem 'rails3-jquery-autocomplete'
gem 'spreadsheet'


group :development, :test do
  gem 'sqlite3', '1.3.5'
  gem 'rspec-rails', '2.10.0'
  gem 'faker', '0.3.1', :require => false
end

# Gems used only for assets and not required
# in production environments by default.
group :assets do
  gem 'sass-rails',   '3.2.4'
  gem 'coffee-rails', '3.2.2'
  gem 'uglifier', '1.2.3'
  gem 'jquery-datatables-rails', github: 'rweng/jquery-datatables-rails'
  gem 'jquery-ui-rails'
end

gem 'jquery-rails', '2.0.2'

group :test do
  gem 'capybara', '1.1.2'
    gem 'factory_girl_rails', '1.0'
  gem 'webrat'
  gem 'cucumber-rails', '1.2.1', :require => false
  gem 'database_cleaner', '0.7.0'
end

group :production do
  #gem 'pg', '0.12.2'
end

关于出了什么问题的任何想法？

我在这篇文章中找到了解决方案:When run bundle get invalid byte sequence in US-ASCII

我所要做的就是将它添加到我的 Gemfile 之上:

if RUBY_VERSION =~ /1.9/
  Encoding.default_external = Encoding::UTF_8
  Encoding.default_internal = Encoding::UTF_8
end
