我已经用各自的安装程序安装了最新版本的ruby和postgre。
具体版本如下：
ruby 3.0.2和devkit，来自：https://github.com/oneclick/rubyinstaller2/releases/download/rubyinstaller-3.0.2-1/rubyinstaller-devkit-3.0.2-1-x64.exe
postgresql 13.3来自：https://www.enterprisedb.com/postgresql-tutorial-resources-training?cid=437 （这是官方页面指向的版本）。
我安装了postgre gem，包括： gem install pg -- --with-pg-dir="C:\path\to\PostGre" 成功安装了pg-1.2.3 gem。
但当我这么做的时候 require 'pg' 在irb中，我收到一条错误消息：

主要错误似乎是“找不到指定的模块”（这里是法语，抱歉）。我怎样才能解决这个问题？
