rails C ne fonctionne pas dans des rails 5

Question

En utilisant la commande dans le terminal à l'intérieur d'un rail 5 application

rails c 

l'erreur jetée est donnée ci-dessous. Je n'ai aucune idée de ce que cela signifie dans une question similaire ici pour laquelle la solution était d'utiliser l'arrêt de ressort. J'ai essayé cela aussi mais non ça donnait toujours la même erreur. ce serait génial si quelqu'un pouvait signaler l'erreur ici.

Answer 1

J'ai eu récemment ce problème quand je mis à jour HomeBrew Je travaille aussi avec des rails 5 et a trouvé cette solution et cela a fonctionné pour moi:

ln -s /usr/local/opt/readline/lib/libreadline.7.0.dylib /usr/local/opt/readline/lib/libreadline.6.dylib

Un autre problème pourrait être quelle version de ruby ​​est dans votre chemin - vérifiez-le également.

ruby -v 
ls -la `which ruby` 

puis vérifiez votre PATH
