рельсы 3, почему я не могу использовать командную строку в Ubuntu?

1 голос
/ 28 февраля 2012

Я использую RubyMine 4 в Ubuntu 11.10, в RubyMine все отлично, я могу запустить сервер, разработать и т. Д., Но когда мне нужно работать в командной строке, я просто ничего не могу сделать. .

Я перешел 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, хотя я могу нормально работать в RubyMine IDE!

Мне нужно было использовать командную строку для удаления драгоценного камня, чтобы обнаружить, что я не могу использовать командную строку, как следует .. 

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 ***

Там нет драгоценных камней ..

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 RubyMine работает нормально

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

вот мое окружение драгоценного камня:

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

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

Установка в командной строке. 

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

Откройте папку .bashrc вВаш домашний каталог. 

user$ vim .bashrc

Отредактируйте и добавьте: 

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

Исходный файл .bashrc и закройте терминал 

user$ source ~/.bashrc
user$ exit

Откройте терминал и проверьте, если rvmработает. 

user$ type rvm | head -1

Если вернется 

rvm is a function

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

rvm requirements

Установите при необходимости.Выберите свой любимый аромат рубина (кажется, что это 1.8.7, если так, следуйте точной команде или замените ее на ваш выбор). 

rvm install 1.8.7

Когда все будет готово, 

rvm use 1.8.7 --default

Если это не сработало, пожалуйста, обновите сообщение, запустив 

which ruby

Попробуйте запустить /bin/bash --login в командной строке, прежде чем делать что-либо связанное с rails.Если это работает, делайте это снова в каждой новой командной строке, которую вы открываете.
