ruby-on-rails-3 - heroku 推送失败，错误为 "An error occurred while installing sqlite3-ruby (1.2.5)"

Question

当我这样做时

git push heroku master

我收到以下消息:

       An error occurred while installing sqlite3-ruby (1.2.5), and Bundler cannot continue.
       Make sure that `gem install sqlite3-ruby -v '1.2.5'` succeeds before bundling.
 !
 !     Failed to install gems via Bundler.
 !
 !     Heroku push rejected, failed to compile Ruby/rails app

我已经安装了 libsqlite3-dev、libsqlite3-0、sqlite3，当我运行时:

gem install sqlite3-ruby -v '1.2.5'

按照错误信息的提示，安装成功:

Successfully installed sqlite3-ruby-1.2.5
1 gem installed
Installing ri documentation for sqlite3-ruby-1.2.5...
Installing RDoc documentation for sqlite3-ruby-1.2.5...

我不确定可能是什么问题。

我的 Gemfile 是:

source 'http://rubygems.org'
gem 'rails', '3.0.1'
gem 'sqlite3-ruby', '1.2.5',:require => 'sqlite3'

我可以知道是什么问题以及如何解决它吗？

Answer 1

Heroku 不支持 sqlite3。

所以您需要将 Gemfile 更改为:

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

group :production do
  gem 'pg'
end

然后再次运行 bundle install
