我正试图在我的笔记本上安装ROR(Debian Wheezy 64位).

首先,我通过第一个答案解决了这个问题(enter link description here).

现在rails服务器启动了,但是在localhost：3000浏览器上我收到以下错误：

Could not load ‘active_record/connection_adapters/sqlite3_adapter’. Make sure that the adapter in config/database.yml is valid. If you use an adapter other than ‘MysqL’,‘MysqL2’,‘postgresql’ or ‘sqlite3’ add the necessary adapter gem to the Gemfile.

我已经安装了ruby 2.0.0编译源代码,没有错误或错误.
然后我安装了一些需要的库(sqlite3,libsqlite3-dev)……

这是我的GemFile：

@H_404_15@'https://rubygems.org' -# Bundle edge Rails instead: gem 'rails',github: 'rails/rails' gem 'rails','4.0.0' -# Use sqlite3 as the database for Active Record gem 'sqlite3' -# Use SCSS for stylesheets gem 'sass-rails','~> 4.0.0' -# Use Uglifier as compressor for JavaScript assets gem 'uglifier','>= 1.3.0' -# Use CoffeeScript for .js.coffee assets and views gem 'coffee-rails','~> 4.0.0' -# See https://github.com/sstephenson/execjs#readme for more supported runtimes -# gem 'therubyracer',platforms: :ruby -# Use jquery as the JavaScript library gem 'jquery-rails' -# Turbolinks makes following links in your web application faster. Read more: https://github.com/rails/turbolinks gem 'turbolinks' -# Build JSON APIs with ease. Read more: https://github.com/rails/jbuilder gem 'jbuilder','~> 1.2' group :doc do -# bundle exec rake doc:rails generates the API under doc/api. gem 'sdoc',require: false end -# Use ActiveModel has_secure_password -# gem 'bcrypt-ruby','~> 3.0.0' -# Use unicorn as the app server -# gem 'unicorn' -# Use Capistrano for deployment -# gem 'capistrano',group: :development -# Use debugger -# gem 'debugger',group: [:development,:test] gem 'execjs' gem 'therubyracer'

在我的database.yml中：

@H_404_15@-# sqlite version 3.x -# gem install sqlite3 -# -# Ensure the sqlite 3 gem is defined in your Gemfile -# gem 'sqlite3' development: adapter: sqlite3 database: db/development.sqlite3 pool: 5 timeout: 5000

我的宝石版：

@H_404_15@ruby 2.0.0 rails 4.0.0 sqlite 1.3.7
