Rake abandonné, erreur lors de la tentative de chargement de la gemme 'uglifier'

Je suis "Mise en route avec Ruby sur Heroku", mais lorsque j'essaie d'exécuter l'application de démonstration localement avec

$ bundle exec rake db:create db:migrate

Je reçois

sam@samoliver:~/Ruby-getting-started$ bundle exec rake db:create db:migrate --trace

J'ai essayé de supprimer et d'ajouter à nouveau 'uglifier' (2.5.3) sans effet et j'ai 'therubyracer' installé, donc je ne comprends pas de quoi se plaint ExecJS.

Gemfile

Uglifier est un compresseur JavaScript, il a donc besoin d'un runtime javascript, essayez d'installer nodejs

Exécutez ceci pour installer NodeJS dans Ubuntu

Sudo apt-get install nodejs

ou

brew install nodejs

si vous êtes sous OSX.

Essaye ça:

gem update --system 1.4.2

J'avais le même problème. Je devais aller dans mon dossier racine (sur l'utilisation d'ubuntu

Sudo su)

À partir de là, utilisez apt-get install nodejs, puis quittez la racine et exécutez bundle install alors vous devriez pouvoir exécuter rake db:migrate
