Question

我正在测试jpg minify的插件grunt-contrib-imagemin。但它总是失败的运行“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-使用OptiPNG

imagemin-jpegtran

<强>解决方案

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

<强> gifsicle

从here
下载 gifsicle.exe 32位解压缩它在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

现在你已经修复了gifsicle问题。不要再退出两次了：）
<强>使用OptiPNG

从此处下载 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
在此处复制解压缩的 optipng.exe 。现在你已经修复了optipng问题。不要再退出了一次：）
<强> jpegtran

下载 jpegtran.exe 和 libjpeg-62.dll 将它们放在 vendor 文件夹里面

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

 Grunt imagemin:dist

命令将成功完成

<强>记住

如果你再次安装grunt，那么将安装grunt-contrib-imagemin这些文件夹不会被覆盖。但是，对于第一个和干净的安装，您需要完成这些步骤。

Answer 3

我有同样的问题atm。我尝试过旧版本，效果很好。在git存储库中存在一个问题，因此您并不是唯一的问题;）

Answer 4

根据Github Ticket #273: (Fatal error: This socket is closed) ，它是由jpegtran-bin Issue #54引起的。两个发布现在都已解决和关闭。

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

致命错误：当我测试grunt-contrib-imagemin时，此套接字已关闭
