为什么 Puppet 使用不同的 ruby 版本

Question

安装puppet后出现如下错误：

我的配置： OS：Centos 6.5 人偶：puppet-server-3.8.7-1.el6.noarch

# rvm list

 rvm rubies

   ruby-2.1.0 [ x86_64 ]
=* ruby-2.4.1 [ x86_64 ]

# ruby --version
ruby 2.4.1p111 (2017-03-22 revision 58053) [x86_64-linux]

为什么木偶使用 ruby 1.8？

Answer 1

rvm 未加载到用户运行 puppet 的环境中，查看您运行 [=13] 所在用户的 .bashrc 和 .profile =] 然后查看 puppet 用户的相同内容。看起来 puppet 用户不了解 rvm，而是使用系统 ruby.

您想在 .profile 中看到如下内容：

$ cat ~/.profile

export PATH="$PATH:$HOME/.rvm/bin" # Add RVM to PATH for scripting

[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm" # Load RVM into a shell session *as a function*

可能是您只为单个用户而不是系统范围设置了 rvm。您可能只想设置它 per-user，但在那种情况下，确实需要为用户运行人偶设置它。
