activos de rake: precompilar RAILS_ENV=la producción no funciona como se requiere

Question

Estoy tratando de precompilar los activos usando el comando rake assets:precompile RAILS_ENV=production , pero siempre obtengo el error a continuación.

** Invoke assets:precompile (first_time)
    ** Execute assets:precompile
    /usr/bin/ruby /usr/bin/rake assets:precompile:all RAILS_ENV=production RAILS_GROUPS=assets --trace
    ** Invoke assets:precompile:all (first_time)
    ** Execute assets:precompile:all
    ** Invoke assets:precompile:primary (first_time)
    ** Invoke assets:environment (first_time)
    ** Execute assets:environment
    ** Invoke environment (first_time)
    ** Execute environment
    ** Invoke tmp:cache:clear (first_time)
    ** Execute tmp:cache:clear
    ** Execute assets:precompile:primary

¿Alguien tiene alguna idea de lo que podría estar mal? Gracias.

Answer 1

¿Has añadido esta gema a tu gemfile?

# Use Uglifier as compressor for JavaScript assets
gem ''uglifier'', ''>= 1.3.0''

mueva esa gema fuera del grupo de activos y luego ejecute Bundle nuevamente, ¡espero que eso ayude!

Answer 2

Descubrí que mi proyecto de copia de seguridad funcionó bien si compilo previamente sin la bundle update . Tal vez algo salió mal con la gema actualizada, pero no sé qué gema tiene un error.

Answer 3

Para explicar el problema, su error es el siguiente:

LoadError: cannot load such file -- uglifier
      (in /home/cool_tech/cool_tech/app/assets/javascripts/application.js)

Esto significa que en algún lugar de application.js , su aplicación hace referencia a uglifier (probablemente en el área de manifest en la parte superior del archivo). Para solucionar el problema, debe eliminar la referencia a uglifier o asegurarse de que el archivo uglifier esté presente en su aplicación, por lo tanto, las respuestas que se le proporcionaron

Fijar

Si no has tenido suerte al agregar la gema a tu GemFile, una solución rápida sería eliminar cualquier referencia a uglifier en tu manifiesto de application.js . Esto, por supuesto, será temporal, pero al menos le permitirá precompilar sus activos

Answer 4

Reemplazar

rake assets:precompile RAILS_ENV=production

con

rake assets:precompile ( RAILS_ENV=production bundle exec rake assets:precompile rake assets:precompile RAILS_ENV=production bundle exec rake assets:precompile es la tarea de rake exacta)

Dado que la precompilación se realiza solo en modo de producción, no es necesario especificar explícitamente el entorno.

Actualizar:

Intente agregar la siguiente línea a su Gemfile:

group :assets do
  gem ''therubyracer''
  gem ''sass-rails'', "  ~> 3.1.0"
  gem ''coffee-rails'', "~> 3.1.0"
  gem ''uglifier''
end

A continuación, ejecute bundle install .

Espero que funcione :)

Answer 5

Tuve este problema hoy. Lo arreglé siendo explícito sobre mi requerimiento

gem ''uglifier'', ''>= 1.0.3'', require: ''uglifier''

Yo tenía el mío todavía en el grupo de activos.
