指定gem安装目录

问题描述

我在这里遇到一些麻烦。我正在使用Rails 2.3项目（通过ssh在生产服务器上工作 - 不要问为什么）。这是。当delayed_jobs尝试启动时，输出说我需要安装捆绑软件gem。问题是gemdir是/var/lib/gems/1.8/，我没有该目录的写入权限。但是我可以在〜/ projects / shared / gems / ruby​​ / 1.8 / gems下面找到一个目录。

如何定义gem的安装路径？

解决方案

您可以将以下内容添加到 config.ru 文件中：

  ENV ['GEM_HOME'] =＃{ENV ['HOME']} / projects / shared / gems / ruby​​ / 1.8 / gems
 ENV ['GEM_PATH'] =＃{ENV ['GEM_HOME']}：/ var / lib /ruby/gems/1.8
 require'rubygems'
 Gem.clear_paths 
  

这将告诉你的机架应用程序在哪里寻找宝石。

同时配置您的服务器 .bashrc ：

  export GEM_HOME =$ HOME / projects / shared / gems / ruby​​ / 1.8 / gems
 export GEM_PATH =$ GEM_HOME：/ var / lib /ruby/gems/1.8
  

I have some trouble here. I am working with a Rails 2.3 project (working on the production server through ssh - don't ask why). Here is the Gemfile. When delayed_jobs is trying to start, the output says I need to install the bundler gem. The problem is that the gemdir is /var/lib/gems/1.8/ and I don't have the write priviliges for that directory. However there is a directory under ~/projects/shared/gems/ruby/1.8/gems where I can write.

How can I define the installation path for a gem?

解决方案

You can add the following to your config.ru file:

ENV['GEM_HOME']="#{ENV['HOME']}/projects/shared/gems/ruby/1.8/gems"
ENV['GEM_PATH']="#{ENV['GEM_HOME']}:/var/lib/ruby/gems/1.8"
require 'rubygems'
Gem.clear_paths

This will tell your rack app where to look for gems.

Also configure your server .bashrc:

export GEM_HOME="$HOME/projects/shared/gems/ruby/1.8/gems"
export GEM_PATH="$GEM_HOME:/var/lib/ruby/gems/1.8"
