我对开发很陌生，只是想为Rails开发设置我的Windows 10 PC。我发现了一个教程，似乎相当清晰和可实现的here。
我可以安装Ruby 3.1.2并将其解压缩到一个永久文件夹。我把它添加到path中，然后继续构建工具。我从他们的网站下载了MSYS 2并安装，然后设置了pacman，然后是RubyInstaller 2--安装了MSYS 2和MINGW开发工具链。我开始安装依赖于C的gems，并能够使用以下命令安装sqlite3：

ridk exec pacman -S mingw-w64-x86_64-sqlite3
gem install sqlite3 --platform ruby

安装nokogiri gem：

ridk exec pacman -S mingw-w64-x86_64-libxslt
gem install nokogiri --platform ruby -- --use-system-libraries

这最后的gem安装行是我失败的地方。我在这方面是个新手，并且即将尝试安装WSL或虚拟机，但我认为尝试排除故障并找到解决方案是明智的。

所以，当我读到“请安装pkg-config rubygem”时，我查找了如何安装，并尝试在MSYS 2中安装，它似乎做到了。
