rails 3, почему я не могу использовать командную строку в ubuntu?

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

Вопрос

Я запускаю RubyMine 4 на Ubuntu 11.10, внутри RubyMine все в порядке, я могу запускать сервер, разрабатывать и т.д..но когда мне нужно поработать в командной строке, я просто ничего не могу сделать..

Я зашел на компакт-диск в каталог своего приложения, затем попытался: 

$ rails s

Я получаю:

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

Странно, почему он не установлен, в то время как я могу нормально работать в RubyMine IDE!

Мне нужно было использовать командную строку для удаления gem, чтобы обнаружить, что я не могу использовать командную строку должным образом..

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 даст мне:

*** LOCAL GEMS ***

никаких драгоценных камней там нет ..

если я наберу :

$ bundle install

Я получаю:

/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

хотя bundle install внутри рубимин работает нормально

итак, чего же мне здесь не хватает?!!почему я не могу использовать командную строку..?

вот мое драгоценное окружение:

если я наберу ruby -v

sam@ubuntu:~/Documents/RoR/course_builder$ ruby -v
ruby 1.8.7 (2011-06-30 patchlevel 352) [i686-linux]
Это было полезно?

Решение

Я не верю, что ваш rvm был настроен правильно.Для простоты давайте начнем с самого начала, следуя приведенным здесь инструкциям:

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

Установите в командной строке.

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

Откройте папку .bashrc в вашем домашнем каталоге.

user$ vim .bashrc

Редактировать и добавлять:

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

Создайте исходный файл .bashrc и закройте терминал

user$ source ~/.bashrc
user$ exit

Снова откройте терминал и проверьте, работает ли rvm.

user$ type rvm | head -1

Если он вернется 

rvm is a function

У нас все хорошо.Проверьте, есть ли у вас все необходимые условия:

rvm requirements

Устанавливайте по мере необходимости.Выберите свой любимый вкус ruby (кажется, это 1.8.7, если да, то следуйте точной команде или замените ее на свой выбор).

rvm install 1.8.7

Когда это будет сделано,

rvm use 1.8.7 --default

Если это не сработало, пожалуйста, обновите сообщение, выполнив

which ruby

Другие советы

Попробуй бежать /bin/bash --login в вашей командной строке, прежде чем выполнять какие-либо rails-сопутствующие материалы.Если это сработает, делайте это снова в каждой новой открываемой вами командной строке.
