Eu tentei desinstalar o rvm para usar o rbenv no meu Mac. Tudo funciona bem até que ruby ​​entra em jogo.

ao usar

<code>rbenv install 1.9.3-p194
</code>

ele compila corretamente, mas depois disso eu gostaria de instalar o bundler .. isso produz o seguinte erro

<code>computer:~ computer$ gem install bundler
/Users/computer/.rbenv/versions/1.9.3-p194/lib/ruby/1.9.1/psych.rb:203:in `parse': (<unknown>): mapping values are not allowed in this context at line 1 column 34 (Psych::SyntaxError)

    from /Users/computer/.rbenv/versions/1.9.3-p194/bin/gem:21:in `<main>'
</code>

Eu então tentei instalar uma versão mais antiga do ruby ​​1.9.3-p125 .. mas mesmo a compilação não terminará com um erro similar que também depende deste interpretador psíquico ... :(

Eu não consegui encontrar algo na net que tivesse os mesmos problemas, então eu peço ..

Eu tentei esses dois recursos que não me ajudaram como se o instalador rbenv estivesse fazendo isso automaticamente

Instalando libyaml para ruby ​​em um mac osX (Lion)

Corrigindo o erro "ruby installation is missing psych"?

Alguém tem uma sugestão? Desde já, obrigado..
