ActionView :: Template :: Error（kids.css未预编译）：

Question

I'm getting this vierd error. I have added kids.css.less to my application.css. I can avoid this error if i add to config.assets.precompile in application(and/or environment file) array, but this is not solution that i would like to use

here is my app.css.less:

/*
 *= require_self
 *= require kids.css.less
 */


 @import "theme_venera.less";

.white-card {
  .kid-word {
    h5 { font-size: @fontSizeSmall;}
  }
}

Which result me in kids.css isnt precompiled.

What am i missing?

UPD: This error happens when i only deploy on my production server. In my dev env i have "live" assets. I'm using capistrano to deploy, and my script containts assets:precompile

Answer 1

在生产模式下运行rake assets:precompile以编译和压缩样式表，然后运行该应用程序。

In development you should be assets debugging (disable the pipeline), to avoid sprockets to concatenate and minify your assets:

config.assets.debug = true

If you don't, Rails expects your assets to be compiled:

rake assets:precompile

And if you don't precompile them, it will try to compile them on request if you enable it:

config.assets.compile = true

Otherwise, if you don't disable the pipeline, don't compile them yourself, and don't allow Rails to do it, it will give you the error you're getting. In production, the usual practice is to precompile them. Live compilation can add a significant overhead, so you shouldn't rely on it. However, it's ok if you leave it enabled after precompiling: Rails will use your compilation first, and if it doesn't find the asset it's looking for there will compile it as an "emergency procedure" to avoid throwing an error.
