英文:
puppetserver gem install adds gem but it's not available for custom functions in the puppet code
问题
我有一个简单的设置：CentOS7 和安装在其上的 Puppet7。服务器正在运行。
我安装了 activerecord-jdbcsqlite3-adapter 适配器用于我的自定义功能。在服务器上可以用 puppetserver gem list 命令看到如下内容：
*** 本地 GEM ***
activemodel (6.1.7.3)
activerecord (6.1.7.3)
activerecord-jdbc-adapter (61.2 java)
activerecord-jdbcsqlite3-adapter (61.2 java)
activesupport (6.1.7.3)
...
...
...
在 custom_function.rb 文件中，这是我的代码（它打印出可以从 Puppet 调用的函数中“看到”的所有 gem 列表）：
require "timeout"
require "erb"
require "rubygems"
Puppet::Functions.create_function(:custom_function) do
dispatch :custom_function do
required_param 'String', :device_name
required_param 'String', :template_name
end
def custom_function(device_name, template_name)
my_local_gems = Gem::Specification.sort_by{ |g| [g.name.downcase, g.version] }.group_by{ |g| g.name }
puts my_local_gems.map{ |name, specs|
[
name,
specs.map{ |spec| spec.version.to_s }.join(',')
].join(' ')
}
puts RUBY_VERSION
end
end
当我在 puppetserver irb 中运行它时，它可以正常工作：
[root@puppet-server ~]# puppetserver irb
irb(main):001:0> require "activerecord-jdbcsqlite3-adapter"
=> true
irb(main):002:0> ActiveRecord::Base.establish_connection(:adapter => "sqlite3", :database => "/db/sqlite.db")
=> #<ActiveRecord::ConnectionAdapters::ConnectionPool:0x2cd31214 @connection_klass=ActiveRecord::Base, @connections=[], @thread_cached_conns=#<Concurrent::Map:0x5d32f5db entries=0 default_proc=nil>, @checkout_timeout=5.0, @mon_data_owner_object_id=4020, @now_connecting=0, @pool_config=#<ActiveRecord::ConnectionAdapters::PoolConfig:0x16f2d883
...
...
...
但是如果我添加了 require "activerecord-jdbcsqlite3-adapter"，我会收到以下错误：
错误: 无法运行: 无法加载文件 -- activerecord-jdbcsqlite3-adapter
英文:
I have simple setup: CentOS7 and Puppet7 running on it. Server is up and running.
I installed activerecord-jdbcsqlite3-adapter adapter for my custom function. This is what I can see on the server with puppetserver gem list

And if I add require "activerecord-jdbcsqlite3-adapter" I am getting error like:
Error: Could not run: cannot load such file -- activerecord-jdbcsqlite3-adapter
And finally. It works well if I run it in puppetserver irb:
[root@puppet-server ~]# puppetserver irb
irb(main):001:0> require "activerecord-jdbcsqlite3-adapter"
=> true
irb(main):002:0> ActiveRecord::Base.establish_connection(:adapter => "sqlite3", :database => "/db/sqlite.db")

Puppet的puppetserver和puppet子系统有单独的Ruby安装。前者是JRuby，而后者是MRI / CRuby。puppetserver gem命令用于操作支持puppetserver的Ruby，但对于您的自定义函数，您可能需要支持puppet的Ruby，因为编译目录使用它。要为后者安装gems，请使用与puppet命令一起捆绑的gem命令，通常位于/opt/puppetlabs/puppet/bin/gem。
英文:
Puppet's puppetserver and puppet subsystems have separate Ruby installations. The former is JRuby, whereas the latter is MRI / CRuby. The puppetserver gem command operates on the Ruby supporting puppetserver, but for your custom function you probably need the one supporting puppet, as that's what the catalog compiler uses. To install gems for that one, use the gem command bundled alongside the puppet command, typically at /opt/puppetlabs/puppet/bin/gem.
