一飲而盡，imagemin可選DEP失敗

Question

正如標題所說，當我嘗試

npm install gulp-imagemin 

它拋出這些錯誤：

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

和插件不工作了，任何人都知道什麼是繼續？謝謝。

我在OSX小牛隊，如果這件事。

Image-min相關性無法安裝。分開安裝軟件包將解決問題：

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