【中文标题】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【英文标题】:Module Build Error: pngquant ENOENT - webpack build succeeds on local OS X, fails on AWS Ubuntu 16.04 server 【发布时间】:2017-05-16 08:52:22 【问题描述】:

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()
  ]

我读到通过降低 pngquant 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index.js 中包含main.scss 文件的位置出错。

 @ ./app/index.js 30:0-39

还有一个我认为与加载器有关的错误:

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片:

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

我尝试过重新安装我的包,只是重新安装 Image-Webpack-Loader,所有基本的事情都要做。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!

【问题讨论】:

嗨,你找到解决办法了吗?现在有点卡住了 据我回忆(该项目最终被废弃),我认为我最终所做的只是删除了图像加载器链中的 image-webpack-loader。我建议尝试一下。 【参考方案1】:

正如 Rohn John 所说,我在我的机器上安装了 pngquantoptipng 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 可以做同样的事情并且更容易:

yarn add pngquant
yarn add optipng
yarn add cjpeg

【讨论】:

【参考方案2】:

图像加载器依赖于pngquant 二进制文件。

当安装pngquant-bin npm 模块时,它使用g++makebashzlib-devlibpng-dev 编译pngquant 二进制文件。

很遗憾,错误消息不够清晰,您只能看到一个无益的消息。

确保在npm installyarn install 之前运行以下命令。

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

【讨论】:

很好的答案我必须将它添加到我的 alpine-node Dockerfile 中才能为我的应用程序正确加载 image-webpack-loader :)【参考方案3】:

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,所以我删除了 node_modules 文件夹并从头开始安装所有内容。 成功了……

【讨论】:

【参考方案4】:

Alpine linux 的 pngquant 有问题,看看这个

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

对此的一种解决方案是通过在安装 npm/yarn 之前从源代码(如 https://git.alpinelinux.org/cgit/aports/tree/community/pngquant/APKBUILD )安装 pngquant 来链接它,但对于我来说,这对于一个软件包来说听起来太多了。

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

【讨论】:

谢谢@avin45h!在没有意识到它可能是节点高山的情况下遇到了一些节点问题。【参考方案5】:

在使用 rails capistrano 部署时遇到了这个问题,其中 node_modules 没有为 pngquant 正确创建。在那里找不到该命令。

最后用 capistrano 再次进行部署。

【讨论】:

【参考方案6】:

好像在安装pngquant时遇到了一些问题。 错误信息 “模块构建失败:错误: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。
