Rails：gem.config&耙宝石：安装 - 没有这样的文件加载 [英] Rails: gem.config & rake gems:install -- no such file to load

问题描述

我试图使用config / environment.rb来安装ruby gem dependency（因为我没有sudo访问我们的服务器; ergo，不能只调用 gem install hpricot ）。

我尝试过包括各种参数（：version ，：source ，：lib ），但我仍然得到 rake中止！没有这样的文件加载 - hpricot

更新：事实证明，当我删除插件hpricot，那么我可以成功执行 rake gems：install 。但这不是很有帮助。这意味着如果我移动我的应用程序，就会遇到无法榨取其宝石的问题（因为我将重新安装插件并添加依赖它的功能）。

这应该如何工作？

解决方案 已被弃用，因为它从未真正起作用。你可以想象有一个gem安装程序依赖于它试图安装的宝石是一个坏主意。

建议使用 bundler ，如果这是一个选项。

Bundler允许您将宝石安装到任何您想要的目的地，专门用于侧面描述整个需要 sudo 问题。它通常像这样简单：

  bundle install --path〜/ my_gems / 
  

您可以通过以下几个简单的步骤，从那里你的生活会更容易。

I'm trying to use config/environment.rb to install a ruby gem dependency (because I don't have sudo access to our server; ergo, can't just call gem install hpricot).

I've tried including sundry arguments (:version, :source, :lib) but I still get rake aborted! no such file to load -- hpricot

Update: It turns out that when I remove the plugin which requires hpricot, then I can execute rake gems:install successfully. But that's not very helpful. It means that if I ever move my app, I run into a problem of being unable to rake its gems (because I will have reinstalled the plugin and added features that depend on it).

How is this supposed to work?

Sys: WinXP, Ruby 1.8.7, Rails 2.3.5

解决方案

rake gems:install has been deprecated because it never really worked. You can imagine having a gem installer with dependencies to the very gems it's trying to install is a bad idea.

It's advisable to use bundler instead if that's an option.

Bundler allows you to install gems to any destination you want, something specifically intended to side-step the whole "requires sudo" problem you describe. It's often as easy as this:

bundle install --path ~/my_gems/

You can make your Rails 2.3.x application use Bundler by following a few simple steps and from there your life will be a lot easier.
