расслоение обновления Рельсы дают погрешность

Question

Вот мой код и вывод в консоли:

root@a:/home/rails/car_main# bundle install 

You have requested: 
    rails = 4.2 

The bundle currently has rails locked at 4.0.2. 
Try running `bundle update rails` 

Вот что я сделал, и выход:

root@a:/home/rails/car_main# bundle update rails

После этого, когда я типа расслоение установить я все еще получаю ошибка

Хорошо. Что мне делать с памятью? Я использую цифровую капельницу океана за 5 долларов, мой сайт довольно прост. я сделал то, что предложил здесь в этом вопросе: https://askubuntu.com/questions/253466/why-am-i-frequently-getting-this-cannot-allocate-memory-error здесь выход:

UPDATE2: печатаю это, как было предложено в комментариях ссылку root@a:/home/rails/car_main# sudo ln -s /usr/bin/gcc /usr/bin/gcc-4.2 проблема все еще существует. Я попытаюсь остановить Postgres Теперь

Update 3 Я пытался остановить и запустить Postgres (я не уверен, если я гуглом том, как это правильно, так вот кода и вывод:

UPDATE 4: Я печатаю HTOP: здесь есть выход: Какие процессы я должен убить

Update 5:

я ра п раз bundle update Тогда я получил ошибку и ПРОМТ установить Bundler поэтому я установил его с

root@a:/home/rails/car_main# apt-get install bundler Тогда я еще раз расслоение обновления:

root@a:/home/rails/car_main# bundle update 
/usr/local/rvm/rubies/ruby-2.3.0/lib/ruby/2.3.0/rubygems/core_ext/kernel_require.rb:55:in `require': cannot load such file -- bundler (LoadError)

    from /usr/bin/bundle:7:in `<main>' 

UPDATE 6: Так я бегом расслоения обновления раз снова, и он дал мне ошибку, что не может установить sqlite3 и предложил установить его вручную, так что я сделал это, и вот результат:

root@a:/home/rails/car_main# gem install sqlite3 -v '1.3.8'

удалю SQLite версии в Gemfile надеюсь, что это помогает
