试图启动时，在US-ASCII无效字节序列的Rails应用程序与PHUSION乘客(invalid

我试图部署使用Phusion乘客和RVM Ubuntu的生产服务器上一个Rails 3应用程序。我已经安装的Phusion乘客成功，但访问我的浏览器服务器时，我收到以下错误：

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.

有关错误的信息可能已被写入应用程序的日志文件。请以分析问题进行检查。

错误信息：在US-ASCII无效字节序列

Exception类：引发ArgumentError

据我了解，Bundler.setup（）开始在一个非ASCII字符的应用程序，并绊倒时被调用。这是有道理的，因为应用程序是一个法国网站，但我确信添加# -*- encoding : utf-8 -*-含非ASCII字符的每一个源文件的顶部。

这里是我的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

任何想法是什么问题呢？

Answer 1:

我发现这个职位的解决方案：在运行时捆绑在US-ASCII得到无效的字节序列

我所要做的就是添加这个在我的Gemfile的顶部：

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

Answer 2:

我有这个问题与运行红宝石1.9.3一个Rails 2.3的应用程序。一个解决办法是降级到1.8.7，但是这是不是你真正想要的。如果在运行Rails应用程序出现此错误（例如，浏览器显示错误消息）将这些行到你的config / environment.rb文件（我把他们的RAILS_GEM_VERSION行之后）：

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

并重新启动应用程序（我总是重新启动整个Apache的，还有其它方法一样）。

Answer 3:

我有这个问题，竟然是在消息文本不恰当的引号。
