ruby - 在 Vagrant 盒子内使用 librarian-puppet - 为什么 puppetlabs/mysql 安装失败？

Question

我在 Vagrant 虚拟机中通过 librarian-puppet 安装 puppetlabs/mysql 时遇到问题。经过大量对话，似乎最有可能的问题是 VirtualBox 不允许共享目录内的符号链接(symbolic link)，但是在应用 vb.customize ["setextradata", :id, "VBoxInternal2/SharedFoldersEnableSymlinksCreate/v- root", "1"] 我看不到行为有任何变化，所以我想知道到底是哪个组件出了问题 - Vagrant、Ruby、Puppet、Librarian、puppetlabs/mysql 模块，或者(大多数可能)我？

在主机上:

$ vagrant --version
Vagrant 1.4.3

在 Vagrant 盒子上:

$ uname -a
Linux host 3.2.0-58-generic #88-Ubuntu SMP Tue Dec 3 17:40:43 UTC 2013 i686 i686 i386 GNU/Linux

$ which ruby
/home/vagrant/.rbenv/shims/ruby

$ ruby --version
ruby 1.9.3p484 (2013-11-22 revision 43786) [i686-linux]

$ bundle --version
Bundler version 1.5.3

$ cat Gemfile.lock | grep -A 3 librarian-puppet
librarian-puppet (0.9.13)
  json
  librarian (>= 0.1.2)
  open3_backport

这是我的Puppetfile:

forge 'http://forge.puppetlabs.com'

# Stuff that we need directly.
mod 'puppetlabs/stdlib'

# 3rd party modules we proxy.
mod 'jfryman/nginx'
mod 'puppetlabs/mysql'
mod 'saz/memcached'
mod 'thomasvandoren/redis'

下面是当我尝试应用上述 Puppetfile 时发生的情况。

值得注意的是，如果我第二次运行完全相同的命令，它将一直运行到完成:

在我看来，那些 Failed to copy from 错误可能是相关的，但我不知道如何理解它们。

Answer 1

通过跟进，这个问题在除 mysql 之外的多个其他模块中重复出现 - 表面上看，问题是这些模块试图在 Vagrant 共享目录中创建符号链接(symbolic link)(这不起作用 [如预期]) .
