la instalación de gemas nokogiri-v ''1.6.8.1'' falla

Question

Construyendo una nueva aplicación de Rails y teniendo un problema con nokogiri. Se dice que intente con gem install nokogiri -v ''1.6.8.1'' que falla con la salida a continuación. Intenté eliminar Gemfile.lock y usar el Gemfile de otra aplicación que no tiene ningún problema: la bundle install aún falla. La falla original es la bundle install que continúa funcionando en otras aplicaciones.

Desde la consola:

gem install nokogiri -v ''1.6.8.1''

IMPORTANT NOTICE:

Building Nokogiri with a packaged version of libxml2-2.9.4.

Team Nokogiri will keep on doing their best to provide security
updates in a timely manner, but if this is a concern for you and want
to use the system library instead; abort this installation process and
reinstall nokogiri as follows:

    gem install nokogiri -- --use-system-libraries
        [--with-xml2-config=/path/to/xml2-config]
        [--with-xslt-config=/path/to/xslt-config]

If you are using Bundler, tell it to use the option:

    bundle config build.nokogiri --use-system-libraries
    bundle install

Note, however, that nokogiri is not fully compatible with arbitrary
versions of libxml2 provided by OS/package vendors.

Answer 1

Ejecuta esto primero:

xcode-select --install

A continuación, vuelva a ejecutar su paquete de instalación

Answer 2

Me encontré con este problema con nokogiri-1.6.8.1 mientras utilizaba bundle install --path vendor/bundle para instalar directamente en un proyecto ubicado dentro de una carpeta de sincronización de Google Drive. El bloqueo parecía estar relacionado con libxml2.

Mientras leía el problema de GitHub al que hacían referencia @Greg y @the_basterd, noté que alguien tenía problemas para instalar en una carpeta de sincronización de Box . Mover la carpeta de mi proyecto a otra ubicación funcionó.

No estoy seguro de cuál es el problema subyacente al instalar en una carpeta de sincronización, pero me interesaría saber si alguien tuvo alguna idea.

No he probado esto con Dropbox, pero quizás eso también cause problemas.

Answer 3

Probé la recomendación de @ the_basterd. Eso no funcionó, pero la referencia era buena, gracias the_basterd. Lo que funcionó de esa referencia fue:

brew install libxml2

bundle config build.nokogiri --use-system-libraries --with-xml2-include=/usr/local/opt/libxml2/include/libxml2

Referencia: https://github.com/sparklemotion/nokogiri/issues/1483

Las publicaciones posteriores en esa referencia dijeron que lo que publiqué arriba "es fuertemente recomendado por los Nokogiri".

brew unlink xz; bundle install; brew link xz Se prefiere el brew unlink xz; bundle install; brew link xz .

También puede encontrar el mismo mensaje de error si ha descargado XCode Tools pero aún no ha aceptado la licencia.

Desde la Terminal, ejecute:

sudo xcodebuild -license

Ingrese su contraseña de administrador, espacio a través del acuerdo y el tipo agree aceptar. Ejecute brew doctor y, si es necesario, brew update y debería estar en buena forma.
