我无法弄清楚如何使用 Apache 托管我自己创建的 Ruby gem。我想知道是否有人可以帮助我找出问题所在。

这是我到目前为止所做的。我首先创建了自己的“hello world”gem（按照这些说明进行操作）：

$ bundle gem helloearth

$ cat lib/helloearth.rb
require "helloearth/version"

module Helloearth
  def self.hi
    puts "hello world"
  end
end

$ cat helloearth.gemspec 
# coding: utf-8
lib = File.expand_path('../lib', __FILE__)
$LOAD_PATH.unshift(lib) unless $LOAD_PATH.include?(lib)
require 'helloearth/version'

Gem::Specification.new do |spec|
  spec.name          = "helloearth"
  spec.version       = Helloearth::VERSION
  spec.authors       = ["Some Guy"]
  spec.email         = ["someguy@example.com"]
  spec.description   = %q{a gem description}
  spec.summary       = %q{a gem summary}
  spec.homepage      = "http://www.example.com"
  spec.license       = "MIT"

  spec.files         = `git ls-files`.split($/)
  spec.executables   = spec.files.grep(%r{^bin/}) { |f| File.basename(f) }
  spec.test_files    = spec.files.grep(%r{^(test|spec|features)/})
  spec.require_paths = ["lib"]

  spec.add_development_dependency "bundler", "~> 1.3"
  spec.add_development_dependency "rake"
end

然后我构建了 gem，安装并运行它以验证它是否有效：

$ gem build helloearth.gemspec
  Successfully built RubyGem
  Name: helloearth
  Version: 0.0.1
  File: helloearth-0.0.1.gem

$ gem install ./helloearth-0.0.1.gem 
Successfully installed helloearth-0.0.1
1 gem installed
Installing ri documentation for helloearth-0.0.1...
Installing RDoc documentation for helloearth-0.0.1...

$ irb
1.9.3-p362 :001 > require 'helloearth'
 => true 
1.9.3-p362 :002 > Helloearth.hi
hello world
 => nil

有用！现在我要卸载我的“hello world”gem（通过清空整个gemset），然后从服务器重新安装它：

$ rvm gemset empty currentgemset
Are you SURE you wish to remove the installed gems for gemset 'ruby-1.9.3-p362@currentgemset' (/home/joe/.rvm/gems/ruby-1.9.3-p362@currentgemset)?
(anything other than 'yes' will cancel) > yes

我需要设置 Apache 来托管这个 gem。我按照http://docs.rubygems.org/read/chapter/18#page81上的说明进行了此操作：

$ sudo mkdir /var/www/gems
$ sudo cp helloearth-0.0.1.gem /var/www/gems
$ rvmsudo gem generate_index -d /var/www/gems/
Warning: can not check `/etc/sudoers` for `secure_path`, falling back to call via `/usr/bin/env`, this breaks rules from `/etc/sudoers`. export rvmsudo_secure_path=1 to avoid the warning.Generating Marshal quick index gemspecs for 0 gems

Marshal.4.8           quick

Apache 现在托管 gem，我可以使用我的网络浏览器在 localhost/gems 成功访问这个目录。但是，我无法从 Apache 服务器安装我的 gem：

$ gem sources -a http://localhost/gems/
http://localhost/gems/ added to sources

$ gem sources
*** CURRENT SOURCES ***

http://rubygems.org/
http://localhost/gems/

cd ~ # leave the directory which holds the local copy of the gem to force use of the Apache server

$ gem install helloearth
ERROR:  Could not find a valid gem 'helloearth' (>= 0) in any repository
ERROR:  Possible alternatives: hello_bar, hello_ext, hellogr, helloh, hellolorem

我还尝试添加 127.0.0.1/gems/ 和 0.0.0.0/gems/ 作为 gem 源，但都没有解决问题。有人告诉我将 --legacy 标志添加到对 $ gem generate_index 的调用中，但这也不起作用。

helloearth-0.0.1.gem 不在 gem generate_index 的正确位置。

如果您希望源为 /gems，则 .gem 文件需要位于 /var/www/gems/gems

gem generate_index -d 调用位于父目录 (BASEDIR) 上，.gem 文件位于 /gems 子目录中。
