rake资产：预编译不起作用

Question

轨-3.2.7

ruby-2.1.0-preview1 [x86_64]

执行命令rake assets:precompile但无法获得任何响应。 当编译完成的css文件没有合并时，只看到像.right{float:right;}这样的代码

 /* * This is a manifest file that'll be compiled into application.css, which will include all the files * listed below. * * Any CSS and SCSS file within this directory, lib/assets/stylesheets, vendor/assets/stylesheets, * or vendor/assets/stylesheets of plugins, if any, can be referenced here using a relative path. * * You're free to add application-wide styles to this file and they'll appear at the top of the * compiled file, but it's generally better to create a new file per style scope. * *= require_self *= require bootstrap_and_overrides *= require nested_sortable *= require tag_it *= require jquery.lightbox-0.5 *= require morris *= require jquery.ui.datepicker *= require articles *= require messages *= require workorder *= require community *= require homepage */ /* require_tree . */ .right { float: right; }

Answer 1

# Compress JavaScripts and CSS
 config.assets.compress = true

# Don't fallback to assets pipeline if a precompiled asset is missed
config.assets.compile = true

在你的production.rb文件中，请检查以上两者是否属实，然后执行并预编译。

Answer 2

1） rake assets:precompile只需将资源从app/assets编译为public/assets 。 因此，尝试删除public/assets并运行rake assets:precompile 。 您应该在public/assets看到已编译的资源。

2）在development环境中，Rails不提供编译资产。 它在运行时编译并分别提供所有资源。 是否意味着您在浏览器中查看application.css ，您只能看到此资源的内容。 其他资源将在其他资源中（查看HTML页面的head部分）

3）如果你想在development环境中提供来自public/assets编译资源（我不明白为什么你想要它，但没关系）你应该在config/environments/development.rb指定config.serve_static_assets = true

FYI：我建议阅读此文章有关的资产管道。

Answer 3

环境文件中的config.server_static_assets = true将不起作用，尤其是在您使用heroku时。

我有这个问题，并尝试了很多东西。 卸载并安装宝石。 这就是诀窍：

rails assets:precompile
