在Heroku上安装fcgi失败

Question

我正在尝试将我的Rails项目推向Heroku。它给出了一些关于fcgi的错误。在我的机器上，我可以很好地安装fcgi。我可以在我的机器上执行gem install fcgi -v '0.8.8'而不会出错。

   Make sure that `gem install fcgi -v '0.8.8'` succeeds before bundling.

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'

看起来你使用的是一个非常老的Rails版本。

Heroku最近更改了所有新的应用程序，默认使用Ruby2.0.0-我建议将

ruby '1.9.3'

在Gemfile的源码行下，将您的应用程序锁定到Ruby 1.9.3，因为您可能会遇到最新版本的Ruby和旧的Rails/gem等问题。
