Jekyll - rdiscount est manquant mais il est installé

Question

Mon site Jekyll a cessé de se générer. Quand je commence à Jekyll, je reçois une erreur de dépendance manquante pour rdiscount:

~/src/markcerqueira.github.com [source] jekyll serve --watch

Please report a bug if this causes problems.

    Dependency Error: Yikes! It looks like you don't have rdiscount or one of its dependencies installed. In order to use Jekyll as currently configured, 
        you'll need to install this gem. The full error message from Ruby is: 'cannot load such file -- rdiscount' If you run into trouble, 
        you can find helpful resources at http://jekyllrb.com/help/!

Pas sûr pourquoi que ce soit réglé, mais l'exécution d'un paquet mise à jour propre et faisceau fixe ce problème.

~/src/markcerqueira.github.com [source] sudo bundle clean --force 
~/src/markcerqueira.github.com [source] bundle update 
~/src/markcerqueira.github.com [source] jekyll serve --watch 

Configuration file: /Users/Mark/Desktop/src/markcerqueira.github.com/_config.yml 
      Source: /src/markcerqueira.github.com 
     Destination: /src/markcerqueira.github.com/_site

Peut-être que la gem json causait des problèmes?
