我是Ruby的初学者。我按照http://rubyonrails.org/download上的步骤安装了 Ruby on rails 并按照 youtube 教程创建了一个名为“Blog”的项目。http://www.youtube.com/watch?v=UQ8_VOGj5H8
但是每当我使用命令rails s
时,它都会报错:
C:/Ruby200-x64/lib/ruby/gems/2.0.0/gems/bundler-1.3.5/lib/bundler/rubygems_integ
ration.rb:214:in `block in replace_gem': Please install the sqlite3 adapter: `ge
m install activerecord-sqlite3-adapter` (sqlite3 is not part of the bundle. Add
it to Gemfile.) (LoadError)
这发生在我的笔记本电脑和 PC 上,都使用 Windows 7。我尝试运行命令gem install activerecord-sqlite3-adapter
,但随后我给出了错误。
C:\Users\Ouye\blog>gem install activerecord-sqlite3-adapter
ERROR: Could not find a valid gem 'activerecord-sqlite3-adapter' (>= 0) in any
repository
ERROR: Possible alternatives: activerecord-jdbcsqlite3-adapter, activerecord-sq
lserver-adapter, activerecord-bq-adapter, activerecord-simpledb-adapter, activer
ecord-mysql2-adapter
我尝试了上述所有替代方案并更新了我的捆绑安装,一些替代方案有效,有些无效。在我尝试了上述所有替代方法并运行“rails s”后,我仍然收到告诉我安装 sqlite3 适配器的相同错误。
这就是我的 gem 文件的样子
source 'https://rubygems.org'
gem 'rails', '3.2.13'
gem 'sqlite3'
group :assets do
gem 'sass-rails', '~> 3.2.3'
gem 'coffee-rails', '~> 3.2.1'
gem 'uglifier', '>= 1.0.3'
end
gem 'jquery-rails'
这是 gem 中的所有捆绑包
