所以我对 Rails 等还是很陌生，过去几个小时我一直在尝试安装它，并且在尝试运行 rails s 时遇到以下错误，或者如果我尝试安装它rails g forem:install

那么我在这里遗漏了什么还是...？

我下载的是这个：https://github.com/radar/forem.heroku.com

【问题讨论】：

文件内容是什么：/home/forem/config/initializers/session_store.r?
它包含：# Be sure to restart your server when you modify this file. Forums::Application.config.session_store :cookie_store, key: '_forums_session' # Use the database for sessions instead of the cookie-based default, # which shouldn't be used to store highly confidential information # (create the session table with "rails generate session_migration") # Forums::Application.config.session_store :active_record_store
'ruby -v' 说什么？
上面写着ruby 1.8.7 (2011-06-30 patchlevel 352) [x86_64-linux]

【解决方案1】：

您遇到的错误是由于您在不支持它的旧版本 Ruby 中使用 Ruby 1.9+ 哈希语法。您需要将 Ruby 升级到 1.9.2 或 1.9.3，或者将 session_store.rb 文件的第二行更改为：

# Be sure to restart your server when you modify this file.
Forums::Application.config.session_store :cookie_store, :key => '_forums_session'

谢谢，我去试试
对，现在我得到了这个：>rails g forem:install >/usr/local/lib/ruby/1.9.1/yaml.rb:56:in <top (required)>': >It seems your ruby installation is missing psych (for YAML output). >To eliminate this warning, please install libyaml and reinstall your >ruby. >/usr/local/lib/ruby/gems/1.9.1/gems/activerecord->3.2.11/lib/active_record/connection_adapters/postgresql_adapter.rb:12>08:in initialize':无法连接到服务器：没有这样的文件或>目录（PG ::错误）>服务器是否在本地运行并接受> Unix域套接字“/tmp/.s.PGSQL.5432”上的连接？
这绝对是一个不相关的问题。我建议打开一个新问题以提高知名度并引起更多关注。
我认为问题可能是因为我对 ruby 进行了不同的灌输，我将重新安装它。
