将主人推到heroku的问题

Question

我正在关注在线铁路教程

一切都很好但是在尝试将主目录推送到heroku时.当它出现时:

Installing rails3_serve_static_assets... done
-----> Gemfile detected, running Bundler version 1.0.0

install everything but sqlite3, here it output:
Installing sqlite3 (0.1.1) /usr/ruby1.8.7/lib/ruby/site_ruby/1.8/rubygems/installer.rb:164:in `install': sqlite3 requires Ruby version >= 1.9.1. (Gem::InstallError)

        from /usr/ruby1.8.7/bin/bundle:19
       FAILED:
 !     Heroku push rejected, failed to install gems via Bundler

现在的问题是:我使用的是ruby 1.9.2,甚至没有安装1.8.7.当我列出我的本地宝石时,bundle有这两个版本:bundler(1.0.2,1.0.1)(我不知道为什么)所以似乎路径有些不好但我不知道如何解决这个问题.谢谢你的帮助.

你走错了路 - Heroku不运行Sqlite,它运行PostgreSQL.部署应用程序时,它会为您创建一个新的database.yml文件.所以你不应该在你的gemfile中指定Sqlite - 你应该只为你的开发环境指定它.

像这样的东西:

group :production, :staging do
  gem "pg"
end

group :development, :test do
  gem "sqlite3-ruby", :require => "sqlite3"
end
