Как использовать rbenv после использования RVM

Question

Я использовал RVM, но теперь я пытаюсь использовать rbenv для тестирования, потому что он используется в учебнике, которое мне понравилось. Я установил rbenv с Homebrew. Тогда я закомментированная линию для загрузки RVM в моем ~/.bash_profile:

[[ -s "$HOME/.profile" ]] && source "$HOME/.profile" # Load the default .profile 

#[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm" # Load RVM into a shell session *as a function* 


eval "$(rbenv init -)" 
export PATH="$HOME/.rbenv/shims:$PATH" 

Я установил Ruby:

$ rbenv install 2.2.1 
$ rbenv global 2.2.1 

, но когда я пытаюсь установить Rails, я получаю эту ошибку:

Возможно ли, что RVM и rbenv работают?

Answer 1

"Gem files will remain installed in /Users/romenigld/.rvm" 

делает вид, что RVM все еще пытается контролировать вашу установку Ruby.

RVM не совместим с rbenv. Per the rbenv docs:

rbenv is incompatible with RVM. Please make sure to fully uninstall RVM and remove any references to it from your shell initialization files before installing rbenv.

Я настоятельно рекомендую прочитать документацию всей rbenv; Он охватывает это, наряду с использованием плагинов, которые улучшают использование rbenv.
