Ruby
如何修復“ruby 安裝缺少 psych(用於 YAML 輸出)”。在 CentOS 上?
在
rvm
CentOS 5.8 上安裝後:[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
有一個警告:
$ 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
我聽從了一些建議:
$ rvm pkg install libyaml Fetching yaml-0.1.4.tar.gz to /home/rails/.rvm/archives Extracting yaml-0.1.4.tar.gz to /home/rails/.rvm/src Prepare yaml in /home/rails/.rvm/src/yaml-0.1.4. Configuring yaml in /home/rails/.rvm/src/yaml-0.1.4. Compiling yaml in /home/rails/.rvm/src/yaml-0.1.4. Installing yaml to /home/rails/.rvm/usr Please note that it's required to reinstall all rubies: rvm reinstall all --force
進而:

太糟糕了,警告仍然存在:
$ 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
我怎樣才能擺脫警告?
更新:(申請
rvm reinstall 1.9.3 --movable

Halting the installation. Making gemset ruby-1.9.3-p286 pristine. Making gemset ruby-1.9.3-p286@global pristine.
之後
rvm pkg install libyaml
,通過以下方式重新安裝 ruby 1.9.3:rvm reinstall 1.9.3 --with-libyaml-dir=/home/rails/.rvm/usr
試試這個:
rvm get head rvm reinstall 1.9.3 --movable
