解决方法：

使用 MSYS2 安装完整依赖

第一步：安装 MSYS2

下载并安装：https://www.msys2.org/

打开 MSYS2 终端

在开始菜单找到 “MSYS2 MINGW64”（注意不是 MSYS2 MSYS）并打开。

第二步：更新包数据库

pacman -Syu

中途可能会要求关闭窗口，关闭后重新打开 MSYS2 MINGW64，再运行一次：

pacman -Su

第三步：安装 Cairo 及完整工具链

pacman -S mingw-w64-x86_64-cairo mingw-w64-x86_64-gcc

再把mingw64\bin文件夹添加到path环境变量中
