在Windows 8上使用Cygwin执行.sh文件时出错

我是Cygwin终端机的初学者。我正在尝试使用Windows 8在Windows 8上运行* .sh文件./file_name.sh，但它显示以下错误。

使用预建的外部

错误：找不到“ make”程序。请安装Cygwin make软件包或定义GNUMAKE变量以指向它。

我已在F驱动器上安装了Cygwin。我用Google搜索这个错误，并设置在变量path 计算机属性 → 高级系统属性 → 环境变量 → Path→ 编辑和可变的路径;F:\cygwin\bin，但不起作用。我怎么解决这个问题？

这是我的file_name.sh脚本：

    echo "Building external dependencies from source"

似乎未安装Cygwin的“ make”软件包。尝试安装它，然后运行脚本。以cyg-apt为例。
