「Rubyのインストールに（YAML出力の場合）精神が欠けている」の修正方法CentOSでは？

Question

CentOS 5.8にrvmをインストールした後：

[Rails@localhost ~]$ rvm -v rvm 1.16.17 [Rails@localhost ~]$ which Ruby ~/.rvm/rubies/Ruby-1.9.3-p286/bin/Ruby [Rails@localhost ~]$ Ruby -v Ruby 1.9.3p286 (2012-10-12 revision 37165) [i686-linux] [Rails@localhost ~]$ which gem ~/.rvm/rubies/Ruby-1.9.3-p286/bin/gem

警告があります：

$ gem -v /home/Rails/.rvm/rubies/Ruby-1.9.3-p286/lib/Ruby/1.9.1/yaml.rb:56:in `<top (required)>': It seems your Ruby installation is missing psych (for YAML output). To eliminate this warning, please install libyaml and reinstall your Ruby. 1.8.24

私は従ったいくつかのアドバイス：

残念ながら、警告はまだ残っています：

$ gem -v /home/Rails/.rvm/rubies/Ruby-1.9.3-p286/lib/Ruby/1.9.1/yaml.rb:56:in `<top (required)>': It seems your Ruby installation is missing psych (for YAML output). To eliminate this warning, please install libyaml and reinstall your Ruby. 1.8.24

警告を取り除くにはどうすればよいですか？

rvm pkg install libyamlの後に、Ruby 1.9.3を再インストールします。

 rvm reinstall 1.9.3 --with-libyaml-dir=/home/Rails/.rvm/usr

Libyamlをインストールする必要があると思います。

$ wget http://pyyaml.org/download/libyaml/yaml-0.1.4.tar.gz $ tar xzvf yaml-0.1.4.tar.gz $ cd yaml-0.1.4 $ ./configure --prefix=/usr/local $ make $ make install

代替リポジトリからlibyaml-develをインストールできます（私はrepoforge.orgを使用しました）：

Sudo rpm --import http://apt.sw.be/RPM-GPG-KEY.dag.txt Sudo rpm -ivh http://pkgs.repoforge.org/rpmforge-release/rpmforge-release-0.5.3-1.el6.rf.x86_64.rpm Sudo yum install -y libyaml-devel
