问题：当使用gem’dm-postgres-adapter’gem’dm-sqlite-adapter’将应用程序推送到Heroku时,我得到了这个.
使用本机扩展安装do_sqlite3(0.10.7)不幸的是,发生了致命错误.请在https://github.com/carlhuda/bundler/issues将此错误报告给Bundler问题跟踪器,以便我们进行修复.谢谢！

我访问了那个github链接,有人遇到了同样的问题,但是被定向到Heroku,https://github.com/carlhuda/bundler/issues/1488.我已经发送电子邮件到Heroku的邮件列表,我正在等待回复.

我遇到了LoadError：没有这样的文件要加载–dm-sqlite-adapter
所以我把它添加到了Gemfile和Gemfile.lock中,这是我所能得到的

我试图在本地安装和设置Postgres,但那是我正在慢慢学习但却无法开始工作的新的痛苦.

我也在这里用一个类似的问题阅读了每一个问题,有些人把我推到了这一点,有些人没有得到提问者的回答而留下一个谜.

的Gemfile

-----------------source :rubygemsgem 'sinatra','1.1.0'gem 'thin','1.2.7'gem 'data_mapper'gem 'dm-postgres-adapter'gem 'dm-sqlite-adapter'

Gemfile.lock的

------------------------...dm-sqlite-adapter (1.2.0)  dm-do-adapter (~> 1.2.0)  do_sqlite3 (~> 0.10.6)...

procfile

--------------------web: bundle exec ruby recall.rb -p $PORT

Recall.rb

---------------------require 'rubygems'  require 'sinatra'require 'data_mapper'DataMapper.setup(:default,ENV['DATABASE_URL'] || "sqlite3://#{Dir.pwd}/recall.db")class Note    include DataMapper::Resource    property :ID,Serial    property :content,Text,:required => true    property :complete,Boolean,:required => true,:default => 0    property :created_at,DateTime    property :updated_at,DateTimeendDataMapper.auto_upgrade!get '/' do    @notes = Note.all :order => :ID.desc    @Title = 'All Notes'    erb :homeend

安装do_sqlite时出错(使用本机扩展安装do_sqlite3(0.10.7)…)只是因为这个gem需要安装sqlite3库,而且它们不在Heroku上.要修复它,请从Gemfile中删除dm-sqlite-adapter(这是do_sqlite上的IDepends).如果你想保留sqlite进行开发并使用Postgres进行生产,你可以使用 Gembundler’s groups：

gem 'dm-postgres-adapter',:group => :productiongem 'dm-sqlite-adapter',:group => :development

这样,postgresql适配器将在Heroku上安装生产,但sqlite将在本地用于开发.

代码中设置Datamapper的行是：

DataMapper.setup(:default,ENV['DATABASE_URL'] || "sqlite3://#{Dir.pwd}/recall.db")

这将查找环境变量DATABASE_URL,如果它存在则使用它,否则使用sqlite url.获取LoadError：没有要加载的此类文件 – dm-sqlite-adapter错误表明此变量实际上未设置.运行heroku配置,应该有DATABASE_URL和SHARED_DATABASE_URL的条目.如果未设置,则需要添加数据库.

看一下处理类似问题的this other SO question.解决方案是运行heroku插件：添加共享数据库：5mb.
