无法解决Ruby错误(缺少心理问题) [英] Unable to resolve Ruby error (missing psych)

问题描述

每当我在服务器上运行Ruby时，都会出现以下错误:

Whenever I run something with Ruby on my server, I get the following error:

/usr/local/rvm/rubies/ruby-1.9.3-p194/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.

我使用RVM将Ruby安装到了VPS.

I installed Ruby using RVM onto my VPS.

我尝试按照Stack Overflow上其他问题的说明安装软件包libyaml，但无济于事.

I’ve tried installing the package libyaml as per instructed in other issues on Stack Overflow, to no avail.

我不确定我的VPS正在运行哪种类型的系统，但是没有apt-get命令.它确实有yum…

I’m not sure what type of system my VPS is running, but it doesn’t have the apt-get command. It does have yum…

推荐答案

我遇到了这个问题，安装libyaml并没有帮助.事实证明，心理需要libyaml-devel.我当时在centos6上，所以我这样做了:

I had this problem and installing libyaml didn't help. It turned out that libyaml-devel was needed by psych. I was on centos6 so I did this:

curl -O http://www6.atomicorp.com/channels/atomic/centos/6/x86_64/RPMS/atomic-release-1.0-14.el6.art.noarch.rpm

sudo  rpm -Uvh atomic-release-1.0-14.el6.art.noarch.rpm

sudo yum install libyaml-devel

rvm reinstall 1.9.3-p194
