问题是我无法在Heroku中部署我的项目，因为它要求卸载gem等。
我通过以下链接在轨道上安装了ruby：http://railsinstaller.org/
$ruby -v
ruby 1.9.3p429 (2013-05-15) [i386-mingw32]
$gem -v
2.0.3
$rails -v
`C:/Ruby193/lib/ruby/site_ruby/1.9.1/rubygems/dependency.rb:296:in
uld not find 'railties' (>= 0) among 12 total gem(s) (Gem::LoadErr
from C:/Ruby193/lib/ruby/site_ruby/1.9.1/rubygems/dependen
to_spec'
from C:/Ruby193/lib/ruby/site_ruby/1.9.1/rubygems/core_ext
:47:in `gem'
from C:/RailsInstaller/Ruby1.9.3/bin/rails:22:in `<main>'`
我不知道为什么rails在昨天正确显示版本时会变成这样。
然后我在Aptana Studio 3中使用了部署向导 显示此结果
$ git push heroku master

我也尝试过这个：
$ gem install sqlite3 -- --with-sqlite3-dir=/c/RailsInstaller/Ruby1.9.3/bin/sql
ite3
Successfully installed sqlite3-1.3.7-x86-mingw32

和此：
$ gem install bundler
Fetching: bundler-1.3.5.gem (100%)
Successfully installed bundler-1.3.5

但我仍然得到同样的错误。我可能做错了什么？
我是Ruby和Rails的新手，这是我第一次将应用程序部署到heroku

Heroku使用postgresql。
https://devcenter.heroku.com/articles/sqlite3
删除sqlite3或将其移至Gemfile中的development组，如下所示：
group :development do
gem 'sqlite3'
end
group :production do
gem 'thin'
gem 'pg'
end
删除Gemfile.lock
运行bundle install --without production
git add .
git commit -am "bundle updating sqlite3"
git push heroku master
