ruby-on-rails – 更新破解Sass框架 – 不兼容的单位：’px’和’em’

分类：Ruby作者：编程之家AI导航网
似乎已经更新了一些破坏指南针或橡皮糖的东西.它几天前工作得很好,直到我更新了我的宝石和宝石文件.现在即使回到早期的gemfile,它仍然给我错误.

我在其中详细介绍了如何重新创建here的详细问题

有谁知道我可以调试这个问题的更好方法？我实际上无法移动它或做任何事情.

怀疑的代码行

从完整的堆栈跟踪中我可以看到错误来自this line in compass,它似乎得到它的变量from this line in Gumby

最小代码量

重现错误所需的最小代码量是Gumby的安装,它已安装在项目here和我的gemfile中,其中包含rails 4.0.

的Gemfile：

source 'https://rubygems.org'

gem 'rails','4.0.2'

gem 'jquery-rails'
gem 'jquery-ui-rails'
gem 'turbolinks'
gem 'sass-rails'
gem 'coffee-rails','~> 4.0.0'
gem 'uglifier','>= 1.3.0'
gem 'compass-rails'

gem 'modular-scale'
gem "slim-rails"

gem 'sqlite3'

gem "mini_magick"
gem 'carrierwave'

gem "fog","~> 1.3.1"

gem "pg"

gem 'will_paginate','~> 3.0.0'

gem 'resque',"~> 1.22.0",:require => "resque/server"

gem 'exception_notification'

gem 'httparty'

gem 'devise'

gem "active_model_serializers"

gem "rails_best_practices"

group :doc do
gem 'sdoc',require: false
end

gem 'bullet'

gem 'rails_12factor',group: :production

解决方法

Gumby和Foundation都依赖于模块化扩展(这是ms()函数的来源).由于两个库都存在相同的问题,因此很可能它们依赖于旧版扩展的行为(特别是因为最近似乎有一个新版本).

将依赖项调整为较旧版本的模块化规模应该可以解决问题,直到Gumby获得修补以使用最新版本.
