ruby on rails - Error al instalar FeedZirra

ruby-on-rails rubygems

Question

Soy nuevo en Ruby on Rails. Estoy entusiasmado con el análisis sintáctico de Feed, pero cuando instalo FeedZirra recibo este error.

Uso Windows 7 y Ruby 1.8.7.

Por favor ayuda. Gracias por adelantado.

Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers.  Check the mkmf.log file for more
details.  You may need configuration options.

Provided configuration options:

  Try passing --with-curl-dir or --with-curl-lib and --with-curl-include
  options to extconf.

Answer 1

Necesita instalar libcurl para la joya de curb , que su aplicación depende de alguna parte. Puedes obtenerlo aquí , pero estás solo en lo que respecta a la instalación. No soy un usuario de Windows, lo siento.

Answer 2

Necesita instalar libcurl no para curb joya de curb , sino para la gema de taf2-curb , simplemente mirando cuidadosamente en el registro de errores. Puede encontrar mi respuesta sobre la instalación en taf2-encintado.

Answer 3

Intenté descargar curl desde el enlace que x1a4 había mencionado. No funciona con ruby ​​1.9.2, incluso con dev toolkit instalado:

C:/>gem install feedzirra -- --with-curl-lib=c:/curl-7.21.3-devel-mingw32/lib --with-curl-include=C:/curl-7.21.3-devel-mingw32/include

También encontré este error en Ubuntu 12.0. Lo siguiente puede ayudar.

sudo apt-get install libcurl3 libcurl3-dbg libcurl3-gnutls libcurl3-nss

gem install feedzirra 

¡¡trabajó!!

Answer 5

En Ubuntu tuve que correr

sudo apt-get install libcurl3-dev

Luego ejecuté la instalación de gem nuevamente y se completó con éxito.
