我最近更新到 rails 4.1.6 和 ruby​​ 2.1.3p242.我还更新了系统上的所有 gem.创建新应用程序后，我在运行服务器时不断收到 pg_ext 加载文件错误.我在带有 PostgreSQL 9.3 的 Windows 8 x64 上.在我之前的 RoR 安装(rails 3.2 和 ruby​​ 1.9.3)下，pg gem 运行良好.

I recently updated to rails 4.1.6 and ruby 2.1.3p242. I also updated all gems on my system. After creating a new app, I keep getting a pg_ext load file error on running the server. I'm on windows 8 x64 with PostgreSQL 9.3. The pg gem was working fine under my previous RoR installation which was rails 3.2 and ruby 1.9.3.

在 gem 的安装目录下，我有一个 2.0/pg_ext.so 文件.我尝试将文件夹重命名为 2.1 并运行服务器.结果是一样的.我认为这是因为 Ruby 不允许 Require .so 文件.以下是错误截图:

Under the gem's installation directory, I've a 2.0/pg_ext.so file. I tried renaming the folder to 2.1 and ran the server. The result was the same. I assume it's cause Ruby doesn't allow to Require a .so file. Below is the screenshot of the error:
