致命错误:当我测试grunt-contrib-imagemin时，此套接字已关闭
我正在测试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
}]
}
}

at TCP.onread (net.js:559:26)原因：
grunt-contrib-imagemin无法下载和测试3个依赖项
imagemin gifsicle
imagemin optipng
图像处理-jpegtran
解决方案
- install grunt-contrib- 0.9.4版
npm缓存清除npm uninstall grunt contrib-imagemin npm install --save-dev grunt-contrib-imagemin@.0.9.4
- gifsicle
从here下载gifsicle.exe 32位
解压缩
在您的make \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
将解压缩的gifsicle.exe复制到供应商文件夹
现在你已经修复了gifsicle的问题。不要退出再多两个去:)
- optipng
从此处下载optipng.exe，在您的make \node_modules\grunt contrib- imagemin\node_modules\imagemin\node_modules\imagemin-optipng\node_module\optipng-bin\上创建一个名为optipng.exe的文件夹
将解压缩的optipng.exe复制到此处。现在您已经修复了optipng问题。不要退出，再来一次就可以了:)
- jpegtran
下载jpegtran.exe和libjpeg-62.dll，将它们放在里面的供应商文件夹中
您可以使用\node_modules\grunt-contrib imagemin\node_modules\imagemin\node_modules\imagemin-jpegtran\node_module\jpegtran-bin\
万岁，你完成了。还有你的
Grunt imagemin:dist命令将成功完成
记住
如果您再次安装grunt，则会安装grunt-contrib-imagemin，这些文件夹将不会被覆盖。但是，对于第一次干净的安装，您需要完成以下步骤。

我的自动取款机也有同样的问题。我试过一个老版本，它工作得很好。在git库中有一个问题，所以在这个问题上你并不孤单;)
