Correction de l'installation de therubyracer/libv8 (0.12.1) sur Mavericks

OK, je suis au bout du rouleau avec ça. Il y a quelques questions similaires, mais elles font toutes référence à therubyracer 0.10 et concluent généralement que le problème peut être résolu en passant à la version 0.12. 

J'ai des problèmes similaires, mais quand j'utilise 0,12.

Questions similaires

J’ai de la difficulté à utiliser gcc «standard» (xcode?), Ainsi que Apple-gcc42 et gcc de homebrew. J'ai essayé à la fois --with-system-v8 et --without-system-v8, et encore une fois, pas de dés.

Voici quelques journaux:

D'ACCORD. Donc, pour résoudre les problèmes liés à therubyracer 0.10, certaines personnes recommandent d’installer breuvage v8, puis de dire à rubygems d’utiliser System v8. Voyons ce qui se passe!

OK, donc ceci est maintenant trié. 

Pour les futures personnes ayant le même problème, je souffrais de la construction de Ruby par rapport à une installation antérieure d’OS X. 

Fixé par Nvm complètement et en partant de zéro, bien que j'imagine que vous pourriez simplement désinstaller/réinstaller Ruby incriminé.

Plus de détails sur la façon dont le problème a été résolu ici:

J'ai pu continuer avec Ruby racer après rm Gemfile.lock Peut-être essayez-vous, ce qui est plus simple que l'option RVM. 

auparavant: J'ai installé la v8 via brew install v8, puis gem install libv8 -v '3.16.14.3' -- --with-system-v8

et je cours 10.10 Yosemite

CloudMagick

J'ai réussi à remettre les choses en marche en exécutant gem install libv8 -v '3.16.14.3' -- --with-system-v8.

Même problème avec OSX 10.9.3, Ruby 2.1.3 et toutes les versions de therubyracer.

Maintenant, je laisse execjs (dépendant de la pierre précieuse) prendre soin de cela.

ExecJS vous permet d'exécuter du code JavaScript à partir de Ruby. Il sélectionne automatiquement le meilleur runtime disponible pour évaluer votre programme JavaScript, puis vous renvoie le résultat sous forme d'objet Ruby.

Utilisateurs OSX

"Apple JavaScriptCore" est fourni par défaut pour JS Runtime sous OSX. Juste installer execjs va résoudre le problème.

Utilisateurs de Linux

Installez node.js. Execjs gem choisira automatiquement node.js comme runtime js.

Sudo apt-get install nodejs

Il se peut que rubygems récupère les fichiers binaires incorrects pour votre système.

Diagnostic:

  • Comparez la sortie de gem env platform à 'Version du noyau' sous  > About This Mac > System Report > Software
  • Si ceux-ci ne correspondent pas (par exemple, Kernel Version: 14.4.0 et x86_64-darwin-12), RubyGems récupère la mauvaise version de therubyracer et libv8 pour votre système

Réparer:

  • à court terme: bundle update therubyracer --platform=x86_64-darwin-14

Ce problème n'existe plus dans la dernière version de therubyracer (0.12.3).

bundle update therubyracer
