我想教自己在rails上的ruby,我試圖創建一個簡單的應用程序開始。我正在按照http://guides.rubyonrails.org/getting_started.html#creating-a-new-rails-project的教程進行操作,但是無法啓動服務器。當我嘗試啓動服務器並轉到本地主機,無法啓動rails服務器 - sqlite3適配器錯誤
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.
我試圖尋找一個解決方案/之所以出現這種情況的其他問題,但無濟於事。
我的Gemfile看起來像這樣
source 'https://rubygems.org'
# Bundle edge Rails instead: gem 'rails', github: 'rails/rails'
gem 'rails', '4.1.6'
# Use sqlite3 as the database for Active Record
gem 'sqlite3'
# Use SCSS for stylesheets
gem 'sass-rails', '~> 4.0.3'
# 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:

gem 'turbolinks'
# Build JSON APIs with ease. Read more: https://github.com/rails/jbuilder
gem 'jbuilder', '~> 2.0'
# bundle exec rake doc:rails generates the API under doc/api.
gem 'sdoc', '~> 0.4.0', group: :doc
# Use ActiveModel has_secure_password
# gem 'bcrypt', '~> 3.1.7'
# Use unicorn as the app server
# gem 'unicorn'
# Use Capistrano for deployment
# gem 'capistrano-rails', group: :development
# Use debugger
# gem 'debugger', group: [:development, :test]
# Windows does not include zoneinfo files, so bundle the tzinfo-data gem
gem 'tzinfo-data', platforms: [:mingw, :mswin]
我使用 紅寶石2.1.3
,當我鍵入
寶石列表
我發現我正在運行 rails 4.1.6 sqlite3(1.3.9 x86-mingw32)
任何人都可以指向正確的方向嗎?
