Rails 3, pourquoi je ne peux pas utiliser la ligne de commande à Ubuntu?

StackOverflow https://stackoverflow.com/questions/9474791

Question

J'exécute Rumbymine 4 sur Ubuntu 11.10, tout va bien à l'intérieur de rubymine, je peux exécuter le serveur, développer, etc. mais, quand j'ai besoin de travailler sur la ligne de commande, je ne peux rien faire.

I CD à mon répertoire d'applications, puis j'ai essayé: 

$ rails s

Je reçois:

The program 'rails' is currently not installed.  You can install it by typing:
sudo apt-get install rails

C'est étrange, comment se fait-il que ce ne soit pas installé, alors que je peux travailler normalement dans Rumbymine IDE!

J'avais besoin d'utiliser la ligne de commande pour désinstaller un gemme, pour découvrir que je ne peux pas utiliser la ligne de commande comme elle le devrait.

sam@ubuntu:~/Documents/RoR/course_builder$ gem uninstall 'capybara-firebug'
ERROR:  While executing gem ... (Gem::InstallError)
    cannot uninstall, check `gem list -d capybara-firebug`

$ gem list -d me donnera:

*** LOCAL GEMS ***

Pas de gemmes là-bas ..

Si je tape:

$ bundle install

Je reçois:

/usr/lib/ruby/vendor_ruby/bundler/rubygems_ext.rb:8:in `require': no such file to load -- rubygems (LoadError)
    from /usr/lib/ruby/vendor_ruby/bundler/rubygems_ext.rb:8
    from /usr/lib/ruby/vendor_ruby/bundler.rb:11:in `require'
    from /usr/lib/ruby/vendor_ruby/bundler.rb:11
    from /usr/bin/bundle:4:in `require'
    from /usr/bin/bundle:4

même si bundle install à l'intérieur de la rubymine fonctionne bien

Alors, qu'est-ce qui me manque ici? !! Pourquoi je ne peux pas utiliser la ligne de commande ..?

Voici mon environnement de gemme:

Si je tape Ruby -v

sam@ubuntu:~/Documents/RoR/course_builder$ ruby -v

Était-ce utile?

La solution

Je ne crois pas que votre RVM a été configuré correctement. Par souci de simplicité, commençons depuis le début après les instructions ici:

http://beginrescueend.com/rvm/install/

Installez dans la ligne de commande.

user$ bash -s stable < <(curl -s https://raw.github.com/wayneeseguin/rvm/master/binscripts/rvm-installer )

Ouvrez votre dossier .Bashrc dans votre répertoire personnel.

user$ vim .bashrc

Modifier et ajouter:

[[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm" # Load RVM function

Sournez votre fichier .bashrc et fermez le terminal

user$ source ~/.bashrc
user$ exit

Rouvrir le terminal et vérifier si RVM fonctionne.

user$ type rvm | head -1

S'il revient 

rvm is a function

Etait bon. Vérifiez si vous avez toutes les conditions préalables:

rvm requirements

Installer si nécessaire. Choisissez votre saveur préférée de Ruby (il semble qu'il soit 1.8.7, si c'est le cas, suivez la commande exacte ou remplacez-la par votre choix).

rvm install 1.8.7

Quand c'est fait,

rvm use 1.8.7 --default

Si cela ne fonctionnait pas, veuillez mettre à jour le message en exécutant

which ruby

Autres conseils

Essayez de courir /bin/bash --login dans votre ligne de commande avant de faire un rails-Les trucs liés. Si cela fonctionne, recommencez dans chaque nouvelle ligne de commande que vous ouvrez.
