如何编写一个在安装RubyGem时被调用的钩子？ [英] How can I write a hook that gets called when a RubyGem is installed?

问题描述

我想编写一段Ruby代码片段，当我的Gem首次通过 [sudo] gem install mygem 安装时运行。它可以做到吗？

解决方案

它看起来并不像它真的被支持。我发现了一个post_install_message属性，您应该可以在gem规范中设置，但不会执行代码。

将你的在线代码打包成你的宝石中的扩展（就像它是一个本地扩展），并提供一个Rakefile来构建扩展（即调用你的代码）。

I'd like to write a Ruby snippet that gets run when my Gem is first installed via [sudo ]gem install mygem. Can it be done?

解决方案

It doesn't look like it's really supported. I found a "post_install_message" attribute that you should be able to set in the gem spec, but that won't execute code.

You may be able to do it by packaging your on-install code as an extension in your gem (as if it were a native extension), and providing a Rakefile to "build" the extension (i.e. call your code).
