我需要在Ubuntu 12.04服务器上安装puppet 3.2.0或更高版本以及ruby 2.0.0-p247。
没有ruby1.8的安装木偶吗？
大多数我的经验来自CentOS，所以我可能会错过简单的apt。
我的设置：
确保没有ruby存在
root@gitlab:~# which ruby root@gitlab:~# ruby --version The program 'ruby' can be found in the following packages: * ruby1.8 * ruby1.9.1 Try: apt-get install <selected package> 从官方ppa安装木偶
root@gitlab:~# cat /etc/apt/sources.list.d/puppetlabs.list deb http://apt.puppetlabs.com precise main deb-src http://apt.puppetlabs.com precise main deb http://apt.puppetlabs.com precise dependencies deb-src http://apt.puppetlabs.com precise dependencies
最新版本的puppet被列在apt中
root@gitlab:~# apt-cache policy puppet|head puppet: Installed: (none) Candidate: 3.3.0-1puppetlabs1 Version table: 3.3.0-1puppetlabs1 0 500 http://apt.puppetlabs.com/ precise/main amd64 Packages 3.2.4-1puppetlabs1 0 500 http://apt.puppetlabs.com/ precise/main amd64 Packages 3.2.3-1puppetlabs1 0 500 http://apt.puppetlabs.com/ precise/main amd64 Packages
安装puppet 3.3.0会自动带上ruby 1.8。

木偶版本
root@gitlab:/tmp/ruby-2.0.0-p247# puppet --version 3.3.0
ruby版本
root@gitlab:/tmp/ruby-2.0.0-p247# ruby --version ruby 1.8.7 (2011-06-30 patchlevel 352) [x86_64-linux]
（注意，ruby是通过更新选项自动安装的）
root@gitlab:/tmp/ruby-2.0.0-p247# ll `which ruby` lrwxrwxrwx 1 root root 22 Sep 18 02:57 /usr/bin/ruby -> /etc/alternatives/ruby* root@gitlab:/tmp/ruby-2.0.0-p247# update-alternatives --list ruby /usr/bin/ruby1.8
然后我从源代码安装ruby 2.0到它自己的目录
./configure --prefix=/usr/bin/ruby2.0
然后注册Ruby 2.0的更新替代品
update-alternatives --install /usr/bin/ruby ruby /usr/bin/ruby2.0/bin/ruby 10
切换到ruby2.0通过更新替代品
root@gitlab:/tmp/ruby-2.0.0-p247# update-alternatives --set ruby /usr/bin/ruby2.0/bin/ruby update-alternatives: using /usr/bin/ruby2.0/bin/ruby to provide /usr/bin/ruby (ruby) in manual mode. root@gitlab:/tmp/ruby-2.0.0-p247# ruby --version ruby 2.0.0p247 (2013-06-27 revision 41674) [x86_64-linux]
我已经做了好几次了，只要which ruby指向除1.8以外的任何版本的ruby，puppet都会返回以下错误：
root@gitlab:/tmp/ruby-2.0.0-p247# puppet --version /usr/bin/ruby2.0/lib/ruby/2.0.0/rubygems/core_ext/kernel_require.rb:45:in `require': cannot load such file -- puppet/util/command_line (LoadError) from /usr/bin/ruby2.0/lib/ruby/2.0.0/rubygems/core_ext/kernel_require.rb:45:in `require' from /usr/bin/puppet:3:in `<main>'
我怎样才能用ruby 2.0安装puppet？
Puppet 3.3与ruby 2.0兼容，因为它被列在木偶的网站上

RVM似乎比我所需要的复杂得多。 另外，常见问题的说不要用sudo，或者以root身份运行，我必须这样做。 https://rvm.io/

我能够通过使用rvm来安装ruby 2.0和puppet 3.3.0
安装木偶
apt-get install puppet
安装rvm
\ curl -L https://get.rvm.io | 庆典
注销并重新login
安装ruby2.0
rvm安装ruby2.0.0-p247
切换到ruby2.0
rvm使用2.0.0-p247
检查$ apt-cache depends puppet的输出$ apt-cache depends puppet ; 你可能可以使用ruby-1.9 ，但至less在2013-09-17， ruby 2.0还没有被打包到Ubuntu中 。
打包版本需要ruby1.8或1.9。 您可以使用不推荐的方法之一来安装它（gem，tarball），例如sudo gem install puppet 。
