I've been trying to install a database as part of my ruby on rails setup. I'm running a 64 bit windows 8, a x64 based machine. My ruby version is 2.1.3p242, rails version is 4.0.0, sqlite3 version is 3.8.6 and postgresql version is 9.3 I first tried to install sqlite3 by following the steps given in this SO answer but I get this error

`require': Could not load 'active_record/connection_adapters/sqlite3_adapter'. Make sure that the adapter in config/database.yml is valid.

我的database.yml有sqlite3的为适配器键的所有三种环境的价值。
接下来，我尝试将其安装正确安装PostgreSQL的。我发射了pgadmin3 GUI和启动数据库服务器。但是，当我开始Rails服务器。我收到以下错误

My database.yml has 'sqlite3' as the value for the adapter key for all three environments.
Next I try to installed postgresql which was installed properly. I fired up the pgadmin3 GUI and started the database server. But when I start the rails server. I get the following error

C:/Ruby21-x64/lib/ruby/gems/2.1.0/gems/pg-0.17.1-x64-mingw32/lib/pg.rb:10:in `re
quire': cannot load such file -- 2.1/pg_ext (LoadError)
