【问题描述】:
我知道这个问题已经被提出了一千次了,我觉得我已经阅读了大多数其他关于它的帖子,但我似乎仍然无法弄清楚这一点。
我刚开始使用 Ruby on Rails,并尝试在我的项目中使用 Compass/Sass/Suzy。它们都可以(大部分)工作,但指南针编译器存在一些问题。
首先使用bundle exec compass watch(有和没有--poll)什么都不做。 (这是假设我理解这个命令的意义,即它可以即时重新编译,我不必刷新页面来查看我的更改,但我可能是错的)
其次,当我在更改 .scss 文件后刷新页面时,编译完成并重新加载页面需要 30-35 秒。这是无法忍受的。我读过最新的“指南针导轨”存在一些问题,但大多数说这是几年前的帖子。最新的 compass-rails 是否可以完美运行,或者是否存在导致此问题的常见问题?
由于我刚刚学习,我只有一个控制器/视图/scss 文件,所以我很肯定我没有任何依赖循环问题。
这是我当前设置项目的方式。 (我认为它设置正确,但也许有人可以指出我做错了什么。)
- 我创建了一个新的 rails 项目并生成了一个“欢迎”控制器
- 修改了我的 application.rb
应用程序.rb
require_relative 'boot'
require 'rails/all'
require 'susy'
require 'compass'
require 'breakpoint'
require 'normalize-scss'
# Require the gems listed in Gemfile, including any gems
# you've limited to :test, :development, or :production.
Bundler.require(*Rails.groups)
module PersonalWeb
class Application < Rails::Application
# Settings in config/environments/* take precedence over those specified here.
# Application configuration should go into files in config/initializers
# -- all .rb files in that directory are automatically loaded.
end
end
- 修改了我的 Gemfile
宝石文件

end
# Windows does not include zoneinfo files, so bundle the tzinfo-data gem

- 运行命令
bundle - 将 application.css 重命名为 application.css.scss
application.css.scss
@import "compass";
@import "breakpoint";
@import "welcome.scss";
- 分别在我的welcome.erb 和welcome.scss 中添加了一些HTML 和sass。
作为进一步的说明,我遇到了每个编译指南针都抛出一个弃用警告的问题。我遵循了here 的建议,这似乎阻止了它。怀疑它涉及但为了防止我的无知妨碍解决方案,我想我会提到它。

我想我会加入我的welcome.scss,以防万一我做了什么愚蠢的事情。
welcome.scss
@import "normalize";
@import "partials/variables";
@import "partials/layout";
@import "partials/mixins";
@import "grids";

编辑 2 我想我应该提到我在 Windows 10 上。
