ruby-on-rails - SessionsController 中的 Rails 2.x Psych::SyntaxError#new

转载作者：行者123 更新时间：2023-12-02 03:51:10

我必须修复旧 Rails 2.3.8 项目中的错误，但我在加载开发环境时遇到了麻烦。

我已经将项目转换为使用 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"

当我使用“脚本/服务器”启动服务器并加载网站时，出现以下错误

我已经尝试重新标记 session Controller ，但它并没有改变错误。

最佳答案

我猜您使用的是 ruby 1.8.7，现在您正在尝试使用具有不同 YAML 解析器的 1.9.3:http://blog.tddium.com/2011/12/01/psych-isnt-syck/

另请注意，rails 2.3 不支持 ruby 1.9.3。使用 ruby 1.8.7 是最简单的。

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-nice-with-utf-8

将 rails 2.3 与 ruby 1.9.3 结合使用并不容易，请参阅:http://developer.uservoice.com/blog/2012/03/04/how-to-upgrade-a-rails-2-3-app-to-ruby-1-9-3/
