Plugins gulp imagemin可选dep失败

如标题所述，当我尝试

npm install gulp-imagemin

它抛出以下错误：

npm WARN optional dep failed, continuing imagemin-gifsicle@1.0.0
npm WARN optional dep failed, continuing imagemin-pngquant@1.0.2

插件不再工作了，有人知道发生了什么吗？谢谢

如果这很重要的话，我会选择OSX Mavericks。

镜像最小依赖项安装失败。单独安装软件包将解决此问题：

npm install imagemin-gifsicle imagemin-pngquant imagemin-optipng imagemin-jpegtran --save-dev

你试过npm缓存清理吗？@Aperçu是的，没有运气。
