移动到生产时错误预编译资产
我正在尝试将我的项目转移到生产中，
尝试去
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! Sass::SyntaxError: Invalid CSS after "}": expected selector or at-rule, was "}" (sass):89 /Users/mac/.rvm/gems/ruby-2.2.3/gems/sass-3.4.23/lib/sass/scss/parser.rb:1207:in `expected' /Users/mac/.rvm/gems/ruby-2.2.3/gems/sass-3.4.23/lib/sass/scss/parser.rb:1137:in `expected' /Users/mac/.rvm/gems/ruby-2.2.3/gems/sass-3.4.23/lib/sass/scss/parser.rb:42:in `parse' /Users/mac/.rvm/gems/ruby-2.2.3/gems/sass-3.4.23/lib/sass/engine.rb:406:in `_to_tree' /Users/mac/.rvm/gems/ruby-2.2.3/gems/sass-3.4.23/lib/sass/engine.rb:281:in `render' /Users/mac/.rvm/gems/ruby-2.2.3/gems/sprockets-3.7.1/lib/sprockets/sass_compressor.rb:48:in `call' /Users/mac/.rvm/gems/ruby-2.2.3/gems/sprockets-3.7.1/lib/sprockets/sass_compressor.rb:28:in `call' /Users/mac/.rvm/gems/ruby-2.2.3/gems/sprockets-3.7.1/lib/sprockets/processor_utils.rb:75:in `call_processor' /Users/mac/.rvm/gems/ruby-2.2.3/gems/sprockets-3.7.1/lib/sprockets/processor_utils.rb:57:in `block in call_processors' /Users/mac/.rvm/gems/ruby-2.2.3/gems/sprockets-3.7.1/lib/sprockets/processor_utils.rb:56:in `reverse_each'
如何找出发生错误的文件？ 即使有–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]
一些说明：
- 它将检查
*.css和*.scss文件，包括子目录。 - 该脚本不会将压缩输出到文件。 这只是一个内存测试。
