gulp imagemin dep失败

Question

正如标题中所述，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
npm WARN optional dep failed, continuing imagemin-jpegtran@1.0.0
npm WARN optional dep failed, continuing imagemin-optipng@1.0.0

插件不再工作了，有谁知道发生了什么吗？谢谢。

我在OSX小牛队，如果这很重要的话。

Image-min依赖项安装失败。单独安装软件包可以解决这个问题：

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