我一直试图找到答案，但它似乎还没有出现。

我正在使用 React-Toolbox、React-Bootstrap 和一些自定义 scss。在我的本地机器上，构建工作正常。当我启动 AWS Ubuntu 服务器并进行基本节点生产设置时，我的图像构建失败。

我正在使用 Image-Webpack-Loader。我将它链接在文件加载器上。

这是我的生产 webpack 文件（对此的任何提示也非常感谢。永远学习）

let webpack = require('webpack');
let HtmlWebpackPlugin = require('html-webpack-plugin');
let ExtractTextPlugin = require('extract-text-webpack-plugin');
const path = require('path');
const autoprefixer = require('autoprefixer');
const modulesPath = path.join(__dirname, 'node_modules');

var HtmlWebpackPluginConfig = new HtmlWebpackPlugin({
  template: __dirname + '/app/index.html',
  filename: 'index.html',
  inject: 'body'
});

var WebpackEnvPlugin = new webpack.DefinePlugin({
  'process.env.NODE_ENV': JSON.stringify(process.env.NODE_ENV || 'production'),
  PORT: JSON.stringify(process.env.PORT)
});

module.exports = {
  entry: [
  './app/index.js'
  ],
  output: {
    path: __dirname + '/dist',
    filename: 'index_bundle.js',
    publicPath: '/assets'
  },
  postcss: [autoprefixer],
  resolve: {
    extensions: ['', '.css', '.scss', '.js', '.json'],
  },
  module: {
    loaders: [
      {
        test: /(\.js)$/,
        exclude: /node_modules/,
        loaders: ['babel']
      },
      { test: /\.css$/,
        exclude : path.join(__dirname, '/node_modules/react-toolbox/'),
        loader: ExtractTextPlugin.extract("style-loader, css-loader!autoprefixer-loader") },
      {
        test: /\.scss$/,
        exclude : path.join(__dirname, '/node_modules/react-toolbox/'),
        loader: ExtractTextPlugin.extract("style-loader", "css-loader!autoprefixer-loader!sass-loader")
      },
      {
        test    : /(\.scss|\.css)$/,
        include : path.join(__dirname, '/node_modules/react-toolbox/'),
        loaders : [
          require.resolve('style-loader'),
          require.resolve('css-loader') + '?sourceMap&modules&importLoaders=1&localIdentName=[name]__[local]___[hash:base64:5]',
          require.resolve('sass-loader') + '?sourceMap'
        ]
      },
      {
        test: /\.(jpe?g|png|gif|svg)$/i,
        loaders: [
            'file?hash=sha512&digest=hex&name=[hash].[ext]',
            'image-webpack?bypassOnDebug&optimizationLevel=7&interlaced=false'
        ]
      }
    ]
  },
  plugins: [
  HtmlWebpackPluginConfig,
  WebpackEnvPlugin,
  new ExtractTextPlugin('css/main.css', {
            allChunks: true
        }),
  new webpack.optimize.OccurenceOrderPlugin(),
  new webpack.optimize.UglifyJsPlugin()
  ]
}

我已经通过降低 pngquant 的质量来阅读，这个问题可能会得到解决，但我没有这样的运气。

当我为不同的图像构建时，我会遇到这些错误：

ERROR in ./app/images/logo.png
Module build failed: Error: spawn /var/www/project/node_modules/pngquant-bin/vendor/pngquant ENOENT
    at exports._errnoException (util.js:1022:11)

    at process._tickCallback (internal/process/next_tick.js:98:9)
 @ ./app/modules/listingpage/listingpage-component.js 55:11-43

我将main.scss文件包含在我的index.js.

ERROR in ./app/stylesheets/scss/main.scss

还有一个我认为与装载机有关的错误：

ERROR in ./app/images/magnifying-glass.png
    Module build failed: Error: spawn /var/www/project/node_modules/pngquant-bin/vendor/pngquant ENOENT
        at exports._errnoException (util.js:1022:11)

     @ ./~/css-loader!./~/autoprefixer-loader!./~/sass-loader!./app/stylesheets/scss/main.scss 6:6846-6890

我使用以下格式包含我的图像：

const logo =  require('../../images/logo.png');

我试过重新安装我的包，只是重新安装 Image-Webpack-Loader，所有基本的事情。再一次，在本地构建良好，不在服务器上构建。我只是不确定我在这一点上做错了什么。在此先感谢您的帮助！

正如 Rohn John 所说，我在我的机器上安装pngquant并optipng解决了问题

sudo apt-get install pngquant optipng
mkdir -p node_modules/pngquant-bin/vendor/
mkdir -p node_modules/optipng-bin/vendor/
ln -s /usr/bin/pngquant node_modules/pngquant-bin/vendor/pngquant
ln -s /usr/bin/optipng node_modules/optipng-bin/vendor/optipng

我测试了 useyarn可以做同样的事情并且更容易：

yarn add pngquant
yarn add optipng
yarn add cjpeg

图像加载器依赖于pngquant二进制。

pngquant-bin安装 npm 模块后pngquant，它使用g++、make、bash和.zlib-devlibpng-dev

不幸的是，错误消息不够清晰，您只会收到一个无益的消息。

npm install确保在或之前运行以下命令yarn install。

apk --no-cache update \ 
&& apk --no-cache add make bash g++ zlib-dev libpng-dev \
&&  rm -fr /var/cache/apk/*

您可以将安装g++ zlib-dev替换为build-base。

似乎 pngquant 安装遇到了一些问题。错误消息 “Module build failed: Error: spawn /var/www/project/node_modules/pngquant-bin/vendor/pngquant ENOENT” 表示在 node_modules/pngquant-bin/vendor/ 中找不到 pngquant。

您可以尝试重新安装 pngquant 或其他一些依赖于 pngquant 的 npm 包。

此外，您应该检查您的 Ubuntu 服务器是否安装了 pngquant。

Alpine linux 的 pngquant 有问题，看看这个

https://github.com/imagemin/pngquant-bin/issues/65

一种解决方案是在安装 npm/yarn 之前通过从源代码（如https://git.alpinelinux.org/cgit/aports/tree/community/pngquant/APKBUILD ）安装它来链接 pngquant ，但这听起来工作量太大给我一个包裹。

我遇到了同样的问题，最终放弃了高山。我现在正在为节点使用标准 docker 映像。

在对 node 和 npm 进行一些更新后出现了同样的问题。尽管更新后一切正常，但由于显示您提到的消息而崩溃。经过大量搜索后，我找不到另一个答案，因此我删除了 node_modules 文件夹并从头开始安装所有内容。有效...

在没有为 pngquant 正确创建 node_modules 的 rails capistrano 部署中遇到了这个问题。在那里找不到该命令。

最后用 capistrano 再次进行部署。
