移动到生产时错误预编译资产

我正在努力将我的项目转移到生产
中

RAILS_ENV=production bundle exec rake assets:precompile

给我一个错误,没有指定它是在哪个文件中.

rake aborted!

如何找出错误发生在哪个文件中？即使用--trace也没告诉我.

在研究时发现了这个问题:https://github.com/rails/sass-rails/issues/368.显然,您必须检查每个文件以找出哪个文件无法编译.

但是您可以创建一个rake任务来帮助完成该过程:

只需将以下代码添加到lib/tasks/assets.rake文件中即可

namespace :assets do

  desc "Find Sass::SyntaxError files..."
  task find_scss_with_error: :environment do
    files = Dir.glob( Rails.root.join("app", "assets", "stylesheets", "**/*")).grep(/.*\.[css|scss]/)
    files.each do |file|
        print "Trying to compile #{file}..."
        template = File.read(file)
        sass_engine = Sass::Engine.new(template)
        begin
            sass_engine.render
            print "[OK]"
        rescue
            print "[ERROR]"
        end
        puts
    end
  end

end

并运行

rake assets:find_scss_with_error

结果:

Trying to compile /data/ruby/scss-comments-failure/app/assets/stylesheets/example.css...[ERROR]
Trying to compile /data/ruby/scss-comments-failure/app/assets/stylesheets/application.css...[OK]
