カピストラーノでレールアプリをデプロイすると、非常に奇妙なエラーが発生します。展開される場合と展開されない場合があります。たとえば、css に何かを追加します (1 つの文字列のみ)。たとえば.my_some_class{width:10px}
、その後、展開は失敗します。これを追加する前に、デプロイはOKです。cssの文字列を1つだけ含む実験的なコミットを行う原因は他に何も変わっていないと確信しています。私の設定：
rails 4.1.0
ruby 2.1.1p76
gem 'capistrano-rails', group: :development
gem 'capistrano-rvm', group: :development
gem 'capistrano-bundler', group: :development

----------------
You appear to have an outdated version of libyaml (0.1.4) installed on your system.
Prior to 0.1.6, libyaml is vulnerable to a heap overflow exploit from malicious YAML payloads.
For more info, see:
https://www.ruby-lang.org/en/news/2014/03/29/heap-overflow-in-yaml-uri-escape-parsing-cve-2014-2525/
The easiest thing to do right now is probably to update Psych to the latest version and enable
the 'bundled-libyaml' option, which will install a vendored libyaml with the vulnerability patched:
gem install psych -- --enable-bundled-libyaml
