Question

我正在尝试遵循此tutorial，当我尝试使用RSpec生成器时

$ rails generate rspec:install

我收到以下错误：

/usr/lib/ruby/gems/1.8/gems/sqlite3-1.3.5/lib/sqlite3.rb:6:in `require': no such file to load -- sqlite3/sqlite3_native (LoadError)
    from /usr/lib/ruby/gems/1.8/gems/sqlite3-1.3.5/lib/sqlite3.rb:6

    from script/rails:6:in `require'
    from script/rails:6

在对同一问题的其他讨论之后，我更改了我的Gemfile以包含以下内容：

group :development, :test do 
  gem 'sqlite3-ruby', :require => 'sqlite3'
  gem 'sqlite3', '1.3.5'
  gem 'rspec-rails'
  gem 'rspec'
end

我注意到它们都已安装后，我在gemfile中添加了rspec和rspec-rails：

Using rspec-core (2.9.0)
Using rspec-expectations (2.9.0)
Using rspec-mocks (2.9.0)
Using rspec (2.9.0)
Using rspec-rails (2.9.0)

我甚至实施过：

$ gem install rspec

也许我没有使用正确的程序进行更新。在我的计算机上保存了Gemfile后，我正在使用捆绑更新和捆绑安装。尝试 rails生成rspec：install 仍然失败。

更新：当我尝试运行资源时，我收到以下错误：

$ rake spec
rake aborted!
no such file to load -- sqlite3/sqlite3_native

更新：我显然搞砸了什么。现在，如果我尝试启动一个新的应用程序，我会收到以下错误。

您的系统上是否安装了SQlite3库？当您查看 / usr / lib / 中的libsqlite3.so（假设您使用的是Linux）时，您会看到它吗？如果没有，那么你可以尝试安装它（通过apt-get / portage /你的软件包管理器），看看是否有帮助。

rails生成rspec：install - 没有要加载的文件--sqlite3 / sqlite3_native（LoadError）
