模块构建错误：pngquant ENOENT - webpack构建在本地OS X上成功，在AWS Ubuntu 16.04服务器上失败

标签： javascript reactjs sass webpack pngquant

我试图找到答案，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服务器并执行基本节点生产设置时，我的图像上的构建失败。

我正在使用Image-Webpack-Loader。我在文件加载器上链接这个。

这是我的生产webpack文件（关于此的任何提示也非常受欢迎。总是向下学习）

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()
  ]
}

我已经读过，通过降低pngquant的质量，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，我遇到了这些错误：

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

我在main.scss中包含index.js文件的错误。

我认为错误与加载器有关：

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片：

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

我已经尝试重新安装我的软件包，只是重新安装Image-Webpack-Loader，所有基本的事情都要做。再一次，在本地构建良好，不构建在服务器上。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了pngquant和optipng并解决了问题

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

我测试了使用yarn可以做同样简单的事情：

yarn add pngquant
yarn add optipng
yarn add cjpeg

答案 1 :(得分：3)

似乎pngquant安装遇到了一些问题。 错误消息 ＆＃34;模块构建失败：错误：spawn / var / www / project / node_modules / pngquant-bin / vendor / pngquant ENOENT＆＃34; 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npm软件包，具体取决于pngquant。

此外，您应该检查您的Ubuntu服务器是否安装了pngquant。

图像加载器依赖于pngquant二进制文件。

安装pngquant-bin npm模块后，使用pngquant，g++，make，bash和{{1}编译zlib-dev二进制文件}。

遗憾的是，错误信息不够清晰，而且你只会得到一个无益的错误消息。

请务必在libpng-dev或npm install之前运行以下内容。

yarn install

您可以改为使用apk --no-cache update \ && apk --no-cache add make bash g++ zlib-dev libpng-dev \ && rm -fr /var/cache/apk/* 替换安装g++ zlib-dev。

Alpine linux存在pngquant问题，请查看此问题

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

对此的一个解决方案是通过在npm / yarn安装之前从源代码（如https://git.alpinelinux.org/cgit/aports/tree/community/pngquant/APKBUILD）安装pngquant来链接pngquant，但对于我来说，对于一个软件包来说，这听起来太多了。

我遇到了同样的问题，最终失去了高山。我现在使用标准的docker image作为节点。

使用rails capistrano部署进入此问题，其中没有为pngquant正确创建node_modules。那里找不到命令。

使用capistrano再次完成部署。

答案 5 :(得分：0)

在对节点和npm进行一些更新后出现了同样的问题。 虽然更新后一切正常，但是通过显示您提到的消息而崩溃了。 经过大量搜索后，我无法找到另一个答案，所以我删除了node_modules文件夹并从头开始安装了所有内容。 它起作用了......
