在带有RVM和最新CentOS的Ruby中安装passenger会导致此错误

Question

我正在尝试安装passenger- install -apache2-module，但是得到了这个错误：

[root@devserver redmine]# passenger-install-apache2-module
/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.

我错过了什么？

Answer 1

看起来passenger在你的Gemfile中，你可以用几种方法来修复它：

运行bundle install

• run NOEXEC=0 passenger-install-apache2-module

的

Answer 2

在Rails项目文件夹中运行passenger-install-apache2-module似乎是不可能的。转到一个文件夹，然后重试。-Íris
