Question

我已将Rails 2站点复制到生产服务器上，当我在生产服务器上运行脚本/服务器时，我得到以下内容：

-bash-3.2$ script/server

我将所有宝石（包括依赖项）冻结到我的代码库中。

我必须将rack-1.0.1冻结到代码库中，并按照here所述修改vendor / rails / actionpack / lib / action_controller.rb。当我这样做时，我将rack-1.0.1 / rack.gemspec复制到rack-1.0.1 / .specification。我注意到该规范文件的格式与我冻结的其他gem的其他.specification文件的格式有点不同。这是一个正常的样本：

--- !ruby/object:Gem::Specification
name: hoe
version: !ruby/object:Gem::Version
  prerelease: false
  segments:
  - 2
  - 6
  - 1
  version: 2.6.1
platform: ruby
authors:
- Ryan Davis
autorequire:
bindir: bin
cert_chain:

和rack-1.0.1：

# -*- encoding: utf-8 -*-

Gem::Specification.new do |s|
  s.name = %q{rack}
  s.version = "1.0.1"

  s.required_rubygems_version = Gem::Requirement.new(">= 0") if s.respond_to? :required_rubygems_version=
  s.authors = ["Christian Neukirchen"]
  s.date = %q{2009-10-18}
  s.default_executable = %q{rackup}
  s.description = %q{Rack provides minimal, modular and adaptable interface for developing web applications in Ruby.  By wrapping HTTP requests and responses in the simplest way $
  s.email = %q{chneukirchen@gmail.com}
  s.executables = ["rackup"]
  s.extra_rdoc_files = ["README", "SPEC", "RDOX", "KNOWN-ISSUES"]
  s.files = ["COPYING", "KNOWN-ISSUES", "README", "Rakefile", "bin/rackup", "contrib/rack_logo.svg", "example/lobster.ru", "example/protectedlobster.rb", "example/protectedlobste$
  s.has_rdoc = true
  s.homepage = %q{http://rack.rubyforge.org}
  s.require_paths = ["lib"]
  s.rubyforge_project = %q{rack}
  s.rubygems_version = %q{1.3.1}
  s.summary = %q{a modular Ruby webserver interface}
  s.test_files = ["test/spec_rack_auth_basic.rb", "test/spec_rack_auth_digest.rb", "test/spec_rack_auth_openid.rb", "test/spec_rack_builder.rb", "test/spec_rack_camping.rb", "tes$

  if s.respond_to? :specification_version then
    current_version = Gem::Specification::CURRENT_SPECIFICATION_VERSION

我找到了解决方案。我没有意识到我有权访问该机器，因此，以root用户身份登录后，我发现gem-1.0.1已安装在该机器上。我删除了并安装了1.1.0，然后服务器启动就好了。然后我从我的项目中删除了rack-1.0.1。

真正的问题是我得到了

RubyGem version error: rack(1.0.0 not ~> 1.0.1) (RuntimeError)

并且需要rack-1.1.0。我的有限用户帐户已安装1.1.0，但由于某种原因，系统尝试使用全局安装的任何内容。多么烦人。

为什么Rails不喜欢这个gem规范？
