Bundler无法找到适用于宝石“sass”的兼容版本。 [英] Bundler could not find compatible versions for gem "sass"

问题描述

我使用中间人3.3.9和

I am using middleman 3.3.9 and

gem 'sass-rails', '~> 4.0.3'
gem 'bootstrap-sass', '~> 3.3.1'
gem 'bootstrap-timepicker-rails'
gem 'sass', '~> 3.2.19'

运行bundle install时，出现此错误：

When I run bundle install, I get this error:

Bundler could not find compatible versions for gem "sass":
      In Gemfile:
        middleman (~> 3.3.9) ruby depends on
          sass (< 4.0, >= 3.4.0) ruby

        sass (3.2.19)

我怎样才能做到这一点？

How can I make this pass?

推荐答案

一个相关的宝石冲突问题。你已经锁定了 sass-rails ，所以它不能引入足够新的 sass 来满足版本 middleman 。

You're having a dependent gem conflict problem. You've locked sass-rails down so it can't bring in a sass that's new enough to satisfy the version of middleman that you're running.

您需要降低版本 middleman ，或者增加版本 sass-rails 。

You need to either lower the version of middleman that you're using, or increase the version of sass-rails.
