收到错误消息"错误：PNGQUANT无法构建，确保在尝试构建NodeJS应用程序时安装了"安装Libpng-dev"。
经过几分钟的故障排除后，我意识到这是由缺失依赖于构建时所需的依赖应用程序引起的。

> node lib/install.js
  ⚠ The `/home/ubuntu/koel/node_modules/pngquant-bin/vendor/pngquant` binary doesn't seem to work correctly
  ⚠ pngquant pre-build test failed
  ℹ compiling from source
  ✖ Error: pngquant failed to build, make sure that libpng-dev is installed
    at ChildProcess.exithandler (child_process.js:294:12)
    at ChildProcess.emit (events.js:198:13)
    at maybeClose (internal/child_process.js:982:16)
    at Process.ChildProcess._handle.onexit (internal/child_process.js:259:5)

修复程序是使用操作系统包管理应用程序安装构建依赖工具。

Ubuntu/Debian：

sudo apt update
sudo apt install -y build-essential gcc make libpng-dev

CentOS Linux.

sudo yum group install "Development Tools"
sudo yum -y install libpng-devel

然后我能够成功建立。
