如果你在Linux系统中遇到Error: pngquant failed to build, make sure that libpng-dev is installed（错误：pngquant构建失败，请确保已安装libpng-dev）问题，请按照以下解决方法操作。
前言 在尝试构建Nodejs应用程序时（在Linux Mint/Ubuntu/Debian系统中安装Node.js 13版本），我不断收到错误消息“Error: pngquant failed to build, make sure that libpng-dev is installed”，经过故障排除后，我意识到这是由构建时所需的依赖项应用程序缺失引起的。 > 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 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) 解决方法是使用操作系统软件包管理应用程序安装构建依赖项工具。
解决方法 针对Ubuntu/Debian版本： sudo apt update sudo apt install -y build-essential gcc make libpng-dev 针对CentOS Linux版本： sudo yum group install "Development Tools" sudo yum -y install libpng-devel 安装完libpng-dev后，我得以成功构建。信息如下： > uglifyjs-webpack-plugin@0.4.6 postinstall /home/ubuntu/koel/node_modules/webpack/node_modules/uglifyjs-webpack-plugin > node lib/post_install.js > node-sass@4.13.1 postinstall /home/ubuntu/koel/node_modules/node-sass > node scripts/build.js Binary found at /home/ubuntu/koel/node_modules/node-sass/vendor/linux-x64-64/binding.node Testing binary Binary is fine > gifsicle@3.0.4 postinstall /home/ubuntu/koel/node_modules/gifsicle > node lib/install.js gifsicle pre-build test passed successfully > mozjpeg@5.0.0 postinstall /home/ubuntu/koel/node_modules/mozjpeg > node lib/install.js mozjpeg pre-build test passed successfully > optipng-bin@3.1.4 postinstall /home/ubuntu/koel/node_modules/optipng-bin > node lib/install.js optipng pre-build test passed successfully > pngquant-bin@4.0.0 postinstall /home/ubuntu/koel/node_modules/pngquant-bin > 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 compiling from source pngquant pre-build test passed successfully pngquant built successfully 注：我希望本文能帮助您使用pngquant开发工具作为依赖项来构建Nodejs应用程序。
