的Gemfile

Question

目标：使用Sinatra + DataMapper + Postgres + Heroku部署一个简单的测试应用

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。请将此错误报告给https://github.com/carlhuda/bundler/issues的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，但被定向到了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: no such file to load -- dm-sqlite-adapter 所以我把它添加到了Gemfile和Gemfile.lock中，这是我能得到的

我曾尝试在本地安装和设置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，有些人向我推进了这一点，有些人没有得到提问者的回答而留下一个谜。

安装do_sqlite（Installing do_sqlite3 (0.10.7) with native extensions...）时的错误只是因为这个gem需要安装sqlite3库，而且它们不在Heroku上。要解决此问题，请从Gemfile中删除dm-sqlite-adapter（这是do_sqlite上的符号）。如果您想保留Sqlite进行开发并使用Postgres进行生产，可以使用Gembundler's groups：

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

这样，postgresql适配器将在Heroku的生产环境中安装，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")

这会查找环境变量DATABASE_URL，如果它存在则使用它，否则使用sqlite url。获得LoadError: no such file to load -- dm-sqlite-adapter错误表明此变量实际上未设置。运行heroku config，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。

查看处理类似问题的this other SO question。解决方案是运行heroku addons:add shared-database:5mb。

使用Sinatra + DataMapper + Postgres + Heroku返回部署一个简单的测试应用程序：安装do_sqlite3（0.10.7）错误
