Instalar Ruby 2D

Clase 23 de 39 • Curso de Ruby

Puedes encontrar las instrucciones de instalación de Ruby2D para diferente plataforma en la página oficial de Ruby2D (http://www.ruby2d.com/learn/get-started/), sin embargo acá te dejo un resumen.

Ruby2D depende de una libreria nativa llamada simple2D (https://github.com/simple2d/simple2d) que debemos instalar para poder utilizar la gema Ruby2D exitosamente.

Para instalar esta librería sigue estas instrucciones:

MacOS

brew tap simple2d/tap brew install simple2d

Windows

En MingW ejecuta el siguiente comando

url='https://raw.githubusercontent.com/simple2d/simple2d/master/bin/simple2d.sh'; which curl > /dev/null && cmd='curl -fsSL' || cmd='wget -qO -'; bash <($cmd $url) install

Alternativamente sigue las instrucciones de instalación de Ruby2D que encuentras en http://www.ruby2d.com/learn/windows/

Linux

Sigue las instrucciones en http://www.ruby2d.com/learn/linux/ dependiendo de tu distribución de Linux.

Installation Ubuntu

$sudo apt install libsdl2-dev libsdl2-image-dev libsdl2-mixer-dev libsdl2-ttf-dev

$gem install ruby2d

En macOS y Windows ya no es necesario instalar Simple2D, con sólo instalar la gema ya ++es suficiente++. En Linux sigue siendo necesario seguir las instrucciones para instalar las dependencias.

Con sólo correr el comando de abajo ya es suficiente, de nuevo, sólo si tienen macOS o Windows.

gem install ruby2d

Igualmente podrían agregarlo a su Gemfile

gem 'ruby2d'

Y correr a continuación

bundle install

Hola, tuve un poco de inconvenientes para instalar ruby2d en Ubuntu, tal vez porque lo uso con WSL, me funciono usar esta documentación .

https://github.com/simple2d/simple2d

Específicamente esta URL

url='https://raw.githubusercontent.com/simple2d/simple2d/master/bin/simple2d.sh'; which curl > /dev/null && cmd='curl -fsSL' || cmd='wget -qO -'; bash <($cmd $url) install

Espero sea de ayuda

Hey guys!! Para todos los que tuvieron problemas instalando simple2d en MingW, encontré la solución. Al parecer el comando que da el profesor está obsoleto, y encontré en la documentación de Github de Simple2D el nuevo comando:

url='https://raw.githubusercontent.com/simple2d/simple2d/master/bin/simple2d.sh'; which curl > /dev/null && cmd='curl -fsSL' || cmd='wget -qO -'; bash <($cmd $url) install

Pueden conseguir mejores instrucciones que en Github del proyecto, ya que la página web de simple2d no tiene el comando.

También me ayudo este vídeo de este ameriacano, pude ver como era la documentación antes en la página de Simple2d y pude actualizar MSYS2, escribiendo este comando

pacman -S make mingw-w64-x86_64-gcc

Por que cuando uso el comando de instalación no me la agrega la gema al archivo gemfile como npm?

gem install tal_libreria

En windows 10, no he probado otros SO

Joan Sebastian Guevara Parra

student•

Si te refieres al hacer

gem install ruby2d

no lo debe de hacer (Realmente él lo hace, pero está localizado en el binario de Ruby, así que es difícil de encontrar)

Alguien sabe como arreglar este error de carga? es wsl

Andrea Rodríguez

student•

Hola, tengo el mismo error ! como pudiste solucionarlo ?

Eduardo Flores

student•

Parece que la url cambio para windows, ahora es

url='https://raw.githubusercontent.com/simple2d/simple2d/master/bin/simple2d.sh'; which curl > /dev/null && cmd='curl -fsSL' || cmd='wget -qO -'; bash <($cmd $url) install

Pueden ver en la pagina de Simple2D el comando actualizado Apartado Windows

en donde se tiene colocar el código compañero, por favor podría ayudarme.

Este link me ayudo con la instalaciòn en Linux/Ubuntu focal.

Install on Ubuntu

Victor Manuel Franco Cañon

student•

Actualmente uso Ubuntu 18.04, preferí instalar “simple2d” con el comando “url=‘’; which curl > /dev/null && cmd=‘curl -fsSL’ || cmd=‘wget -qO -’; bash <($cmd $url) install”

Por si a alguien más le interesa instalarlo con un solo comando.

Hola , por favor si alguien ha instalado en Windows para que me colabore. tengo el siguiente problema cuando instalo la gema habiendo seguido los pasos anteriores.

== Ruby 2D Installation Errors =======================================

Ruby 2D uses a native library called Simple 2D, which was not found. To install, follow the instructions at ruby2d.com/learn

=======================================================================

extconf failed, exit code 1

Gem files will remain installed in C:/Ruby25-x64/lib/ruby/gems/2.5.0/gems/ruby2d-0.8.1 for inspection. Results logged to C:/Ruby25-x64/lib/ruby/gems/2.5.0/extensions/x64-mingw32/2.5.0/ruby2d-0.8.1/gem_make.out PS C:\Users\FamiliaBS\Desktop\RUBY\snake>

el único paso que no he seguido es incluir el simple2d al PATH, ya que no sé cómo. este es un mensaje que me aprece cuando instalo el simple2d pero no sé como hacerlo

Remember to add %LOCALAPPDATA%\simple2d to your %PATH%

agradezco sus comentarios. Saludos!

Puff es un show tratar de que esto funcione en Windows yo actualmente trabajo desarrollando con rails :P pero uso contenedores no se por que se tomo la decisión de hacer un curso basico de Ruby con la creación de un juego voy a tener que dejar esta parte trunca y me ire directo al de Ruby On Rails ya que cualquier cosa de consola o web no tengo problemas corriendolo en Docker

Tengo el mismo problema, posiblemente por la versión Mojave de mi Mac es mi teoria. Tal vez te funcione un brew upgrade de este link https://github.com/ruby2d/ruby2d/issues/134 Y desinstalar el simple2d (brew remove simple2d) y ruby2d y volver a instalar.
