在Heroku上安装fcgi失败

Question

我试图将我的Rails项目推到Heroku上。它给出了关于fcgi的一些错误。在我的机器上，我可以很好地安装fcgi。我可以在我的机器上无误地执行gem install fcgi -v '0.8.8'。

    An error occurred while installing fcgi (0.8.8), and Bundler cannot continue. 
    Make sure that `gem install fcgi -v '0.8.8'` succeeds before bundling. 

的Gemfile：

source 'http://rubygems.org' 

gem 'rails', '3.0.11' 

#gem 'mysql2', '~> 0.2.17' 

group :development, :test do 
    gem 'sqlite3' 
end 

group :production do 
    gem 'pg' 
end 

# Use unicorn as the web server 
# gem 'unicorn' 

# Deploy with Capistrano 
# gem 'capistrano' 

# To use debugger (ruby-debug for Ruby 1.8.7+, ruby-debug19 for Ruby 1.9.2+) 
# gem 'ruby-debug' 
# gem 'ruby-debug19', :require => 'ruby-debug' 

# Bundle the extra gems: 
# gem 'bj' 
# gem 'nokogiri' 
# gem 'sqlite3-ruby', :require => 'sqlite3' 
# gem 'aws-s3', :require => 'aws/s3' 

# Bundle gems for the local environment. Make sure to 
# put test-only gems in this group so their generators 
# and rake tasks are available in development mode: 
# group :development, :test do 
# gem 'webrat' 
# end 
gem 'fcgi' 
gem 'minitest'

它看起来像您使用的是真正的老版本的Rails的出现。

的Heroku最近更改所有新应用程序默认为使用Ruby 2.0.0 - 我建议把

ruby '1.9.3' 

在你的Gemfile源线下锁定您的应用程序的Ruby 1.9.3，你可能遇到与最新版本的Ruby和旧的Rails /宝石等问题。
