我正在测试用于 jpg minify 的插件 grunt-contrib-imagemin。但它总是失败，因为正在运行“imagemin：dynamic”（imagemin）任务致命错误：此套接字已关闭。

Source :
 grunt.initConfig({
        imagemin: { // Task
           dynamic: {                         // Another target
        files: [{
        expand: true,                  // Enable dynamic expansion
        cwd: 'src/',                   // Src matches are relative to this path
        src: ['**/*.{png,jpg,gif}'],   // Actual patterns to match
        dest: 'dist/'                  // Destination path prefix
      }]
    }
        }
    });

原因：

grunt-contrib-imagemin 无法下载和测试 3 个依赖项

imagemin-gifsicle

imagemin-optipng

imagemin-jpegtran

解决方案

  1. 安装 grunt-contrib-imagemin 0.9.4 版本

    npm cache clear

npm uninstall grunt-contrib-imagemin

npm install --save-dev grunt-contrib-imagemin@.0.9.4

  2. gifsicle

    从这里下载gifsicle.exe 32 位

    解压它
    在 yourapp\node_modules\grunt-contrib-imagemin\node_modules\imagemin\node_modules\imagemin-gifsicle\node_modules\gifsicle\ 上创建一个名为 vendor 的文件夹

    将提取的gifsicle.exe复制到供应商文件夹

    现在您已经解决了 gifsicle 问题。不要退出还有两个去:)

  3. 优化

    从这里下载optipng.exe在 yourapp\node_modules\grunt-contrib-imagemin\node_modules\imagemin\node_modules\imagemin-optipng\node_module\optipng-bin\ 上创建一个名为 vendor 的文件夹

    在此处复制提取的 optipng.exe。现在您已经修复了 optipng 问题。不要退出还有一个去:)

  4. jpegtran

    下载jpegtran.exe和libjpeg-62.dll 放到vendor文件夹里面

    yourapp\node_modules\grunt-contrib-imagemin\node_modules\imagemin\node_modules\imagemin-jpegtran\node_module\jpegtran-bin\

万岁，你完成了。和你的

 Grunt imagemin:dist

命令将成功完成

记住

如果您再次安装 grunt，这将安装 grunt-contrib-imagemin，这些文件夹将不会被覆盖。但是，对于第一次和干净的安装，您需要完成这些步骤。

根据 Github Ticket #273 ：（致命错误：此套接字已关闭）它是由 jpegtran-bin问题 #54引起的。两者都已解决并已关闭。

安装 grunt-contrib-imagemin 0.9.2 通过运行为我解决了这个问题

npm cache clean
npm install grunt-contrib-imagemin --save-dev

我有同样的问题atm。我试过一个旧版本，它工作得很好。你的 git 存储库中有一个问题，所以你并不孤单；）
