我必须修复旧的Rails 2.3.8项目中的错误，并且我在加载开发环境时遇到了麻烦。
I've converted the project to use bundler, here is my Gemfile: 我已将项目转换为使用bundler，这是我的Gemfile：
source :gemcutter
gem "rails", "2.3.8"
gem "pg"
gem 'rdoc'
gem "haml"
gem "will_paginate", '~> 2.3.11'
# RESTful ACL support.
gem "restful_acl", "3.0.4"
# awesome nested set for sub categories
gem "awesome_nested_set", "< 2.0"
# rspec tests
gem 'machinist', "< 2.0"
gem "rspec", "1.3.0"
gem "rspec-rails", "1.3.2"
gem "test-unit"
# Deployment
gem "capistrano"

I've tried remarking out the sessions controller and it doesn't change the error. 我已经尝试重新显示会话控制器，它不会更改错误。

I guess you were using ruby 1.8.7, and now you are trying to use 1.9.3 which has different YAML parser: http://blog.tddium.com/2011/12/01/psych-isnt-syck/ 我猜你使用的是ruby 1.8.7，现在你正在尝试使用1.9.3，它有不同的YAML解析器： http ： //blog.tddium.com/2011/12/01/psych-isnt-syck/
Also note that rails 2.3 does not support ruby 1.9.3. 另请注意，rails 2.3不支持ruby 1.9.3。 It would be easiest to use ruby 1.8.7. 使用ruby 1.8.7最简单。
Switch to ruby 1.9.2 should not be hard, you would probably need utf8 patch: http://blog.kennejima.com/post/835166063/making-ruby-1-9-rails-2-3-to-play-nice-with-utf-8 切换到ruby 1.9.2应该不难，你可能需要utf8补丁： http ： //blog.kennejima.com/post/835166063/making-ruby-1-9-rails-2-3-to-play-不错，用UTF-8
Using rails 2.3 with ruby 1.9.3 is not that easy, see: http://developer.uservoice.com/blog/2012/03/04/how-to-upgrade-a-rails-2-3-app-to-ruby-1-9-3/ 使用带有ruby 1.9.3的rails 2.3并不容易，请参阅： http ： //developer.uservoice.com/blog/2012/03/04/how-to-upgrade-a-rails-2-3-app-to -ruby-1-9-3 /

A work around for this is to not get gems from rubygems.org. 解决这个问题的方法是不要从rubygems.org获取宝石。 You can do this by specifying a GitHub repo for a gem instead of letting bundler download it from rubygems.org. 您可以通过为gem指定GitHub repo而不是让bundler从rubygems.org下载它来完成此操作。
The problem is in the charset being served by the host from which you download the rubygem, if I remember correctly. 如果我没记错的话，问题在于你下载rubygem的主机所服务的charset。
