Question

我正在尝试在ubuntu客户端上安装puppet。我执行了以下步骤：

cd /tmp
wget https://apt.puppetlabs.com/puppetlabs-release-trusty.deb
sudo dpkg -i puppetlabs-release-trusty.deb
sudo apt-get update
sudo apt-get install libcurl4-gnutls-dev libxml2 libxml2-dev libxslt1-dev ruby-dev
echo "deb http://ftp.us.debian.org/debian/ wheezy main contrib non-free" | sudo tee /etc/apt/sources.list.d/debian_stable.list
sudo apt-get update
sudo apt-get install libaugeas-ruby1.9.1 augeas-tools
sudo apt-get install puppet

我收到此错误：

@ubuntu:~$ puppet -V

如果我在这里遗漏了任何东西，那将会很棒。

目前没有任何版本的Puppet支持Ruby 2.2+。即使是最新版本的Puppet（v4.8）也不支持2.2 +：

系统要求

红宝石
  使用以下版本的MRI（标准）Ruby：

的2.1.x
  2.0.x版本
  1.9.3

注意：我们目前只测试和包装2.1.x版本的Ruby，因此我们建议您仅使用此版本。我们的测试不包括其他解释器和Ruby版本。

<强>解决方案：
降级到Ruby 2.1。

添加到Gemfile：

gem 'safe_yaml', '~> 1.0.4'

在安装木偶客户端后执行puppet -V时获取与ruby相关的错误
