Почему я не могу установить рельсы с gem install rails -v 4.0.0?

Question

Я установил на GNU/Linux:

РВМ 1.23.16 (стабильный) от Wayne E. Seguin, Михал Papis [https://rvm.io/]
рубинового 2.0.0p247 (2013- 06-27 пересмотр 41674) [x86_64-darwin12.4.0]

я, видимо, есть все драгоценные камни в моей системе, но когда я запускаю команду: gem install rails -v 4.0.0 он утверждает, что был установлен один драгоценный камень. Но Rails еще не установлен.

Когда я использую gem install rails -v 4.0.0 или gem install rails --version=4.0 происходит что:

Как я могу установить Rails 4.0.0 с помощью RVM?

Answer 1

Эти сообщения об ошибках создаются в то время как документация Rails будет установлен на вашем компьютере. Я нашел две проблемы с Rails, обсуждая это: #9590 и #11814.

Это, в конечном счете, an issue with rdoc and ruby 2.0, что было fixed, но пока не опубликована версия rdoc.

Есть несколько способов, чтобы обойти эту проблему, я перечисляю их в порядке, я бы, наверное, попробовать их:

1. Не устанавливайте документацию с драгоценным камнем рельсов; вместо запуска gem install rails do gem install rails --no-rdoc --no-ri. Я почти никогда не использовал встроенную документацию, поэтому у меня есть gem: --no-ri --no-rdoc в моем ~/.gemrc файле, чтобы документация никогда не была установлена ​​для какого-либо драгоценного камня.

2. Установить рельсы без документации, как в # 1, но затем построить документацию вручную, используя RDoc и --exclude='.dat' флаг, как rdoc --exclude='.dat' activesupport/lib строить ActiveSupport документы, as recommended in this comment.

3. Установите rdoc из github при фиксации, который позже ceb81dd11. Использование опций bundler git или github в вашем Gemfile облегчает это, но должны быть другие причины, по которым новая версия еще не выпущена, поэтому могут быть ошибки.

Answer 2

запустить эту команду

$ . ~/.bash_profile 

после РВМ установки

Answer 3

Я занимался этим много, работая с новыми пользователями рельсов, и часто пропущенные пользователи перезапускают терминал (или любую другую оболочку) после установки. Тот факт, что вы видели драгоценный камень, установлен, но не смог найти его сразу после того, как это может быть симптомом. (Знай свое старое сообщение, но пытаясь облегчить боль.)
