列出宝石的非ruby依赖关系的最佳方式是什么？ [英] What's the best way to list a non-ruby dependency of a gem?

问题描述

我正在写一篇红宝石，我想使用一个以Python形式发布的开源程序。我没有时间将python程序移植到ruby，我想尽可能自动管理外部依赖项。

我正在考虑使用Gem.pre_install挂钩自动easy_install我感兴趣的python包。

http://rubygems.rubyforge.org/rubygems-update/Gem.html#method-c-pre_install

如果是公认的做法，我会很感激更好的方法或pre_install的支持。

这是一个老问题，但值得回复。对不起，我没有检查与babushka相关的问题的stackoverflow：）

如果python包可用作点，那么你可以做这样的事情：

  dep'blah.gem'do 
需要'something.pip'
结束
 
 dep'something.pip'
  

然后， babushka blah.gem 会处理安装，包括根据需要安装rubygems和pip。

I am writing a ruby gem that I would like to use an open source program distributed as python. I don't have the time to port the python program to ruby, and I want to manage the external dependency as automatically as possible.

I'm thinking of using the Gem.pre_install hook to automatically easy_install the python package I'm interested in.

http://rubygems.rubyforge.org/rubygems-update/Gem.html#method-c-pre_install

I'd appreciate suggestions of better ways, or support of pre_install, if it's the accepted practice.

解决方案

Quite an old question, but worth a reply. Sorry, I haven't been checking stackoverflow for babushka-related questions :)

If the python package is available as a pip, then you could do something like this:

dep 'blah.gem' do
  requires 'something.pip'
end

dep 'something.pip'

Then, babushka blah.gem would handle the install, including installing rubygems and pip as required.
