我遇到了在Vagrant虚拟机中通过puppetlabs/mysql安装librarian-puppet的问题。经过大量的对话，似乎最有可能的问题是VirtualBox不允许在共享目录中使用符号链接，但是在应用vb.customize ["setextradata", :id, "VBoxInternal2/SharedFoldersEnableSymlinksCreate/v-root", "1"]后我看到行为没有变化，所以我不知道是什么组件实际上是错误的 - Vagrant，Ruby，Puppet，Librarian，puppetlabs / mysql模块，或者（很可能）我？
在主持人身上：
$ vagrant --version
Vagrant 1.4.3
在Vagrant框中：
$ 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'
当我尝试应用Puppetfile时，会发生什么。

在我看来，那些Failed to copy from错误可能是相关的，但我不知道该怎么做。
答案 0 :(得分：0)
通过跟进，除了mysql之外，这个问题在多个其他模块中重复出现 - 问题表面上是这些模块试图在Vagrant共享目录中创建符号链接（这不起作用[如预期]）
