desplegar una aplicación sencilla prueba con Sinatra + + DataMapper Postgres + Heroku devuelve: Instalación do_sqlite3 (0.10.7) de error

Question

Meta: Implementar una aplicación sencilla prueba con Sinatra Postgres + + + DataMapper Heroku

Edición : Cuando uso gem 'dm-postgres-adapter' gem 'dm-sqlite-adapter' para enviar la aplicación a Heroku obtengo esto. Instalación de do_sqlite3 (0.10.7) con extensiones nativas Desafortunadamente, se ha producido un error fatal. Informe este error al rastreador de problemas de Bundler al https://github.com/carlhuda/bundler/issues para que podamos solucionarlo. ¡Gracias!

He visitado el enlace de github y alguien tuvo el mismo problema pero es dirigido a Heroku, https://github.com/carlhuda/bundler/issues/1488. He enviado un correo electrónico a la lista de correo de Heroku y estoy esperando una respuesta.

me encontré con LoadError: no such file to load -- dm-sqlite-adapter por lo que añade que en el Gemfile y Gemfile.lock y esto es por lo que nunca puede conseguir

he tratado de instalar y configurar localmente Postgres, pero eso es nuevo conjunto de dolores que estoy aprendiendo poco a poco pero todavía no puedo trabajar.

También he leído todas y cada una de las preguntas aquí con un problema similar, algunos me han progresado hasta este punto y algunos no tienen respuestas del autor de la pregunta y lo dejan en un misterio.

El error al instalar do_sqlite (Installing do_sqlite3 (0.10.7) with native extensions...) es simplemente porque esta joya requiere las bibliotecas SQLite3 para ser instalados, y que no están en Heroku. Para solucionarlo, elimine dm-sqlite-adapter (que es lo que se identifica en do_sqlite) desde su Gemfile. Si desea mantener SQLite para el desarrollo y el uso de Postgres para la producción, puede utilizar Gembundler's groups:

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

De esta manera, se va a instalar el adaptador de PostgreSQL en la producción de Heroku, pero SQLite se utilizará para el desarrollo a nivel local.

La línea en su código que configura DataMapper es:

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

Esto busca una variable de entorno DATABASE_URL y si está presente la usa de otro modo utiliza la url SQLite. Obtener el error LoadError: no such file to load -- dm-sqlite-adapter sugiere que esta variable no está realmente establecida. Ejecute heroku config, debe haber entradas para DATABASE_URL y SHARED_DATABASE_URL.Si no están configurados, debe agregar la base de datos.

Eche un vistazo a this other SO question que se ocupa de un problema similar. La solución allí era ejecutar heroku addons:add shared-database:5mb.
