未定义的方法“有吗？”对于 Sass::Util:Module (NoMethodError) - Debian 使用 Ruby、Sass、Compass 时出错

Question

我搜索了以下问题的解决方案，但我找不到任何东西。所以我希望你能帮助我。谢谢。

我有：

Debian Stretch（发行版：Debian GNU/Linux 9.7，内核：Linux 4.9.0-8-amd64 (x86_64)）；
Apache NetBeans 10（孵化） - 从 https://snapcraft.io/netbeans;
PHP 7.1.

我安装了（通过 this 页面启发自己：

Ruby（含：sudo apt install ruby-full）；
Sass（含sudo gem install sass）；
罗盘（含sudo gem install compass）；

并检查了他们的版本：

# ruby --version
ruby 2.3.3p222 (2016-11-21) [x86_64-linux-gnu]

# sass --version
Ruby Sass 3.7.3

# compass --version
Compass 1.0.3 (Polaris)

请注意，我没有使用 Ruby 的经验。

我有以下 NetBeans 设置:

*) 在选项卡中 "Tools > Options > HTML/JS > CSS Preprocessors":

Sass Path: /usr/local/bin/sass

我也试过：

Sass Path: /usr/local/bin/scss

*) 在选项卡中 "File > Project Properties > CSS Preprocessors > Sass":

Input: /web/src/Application/assets/scss
Output: /web/public/assets/css
Compiler Options: --compass -E "UTF-8" --trace --no-cache

回溯：

当我尝试编译 .scss 文件时（为了创建相应的 .css 文件）我收到了每个文件的错误。这是第一个 .scss 文件的回溯：

urls.rb 文件:

这是回溯中指定文件的开始内容(/var/lib/gems/2.3.0/gems/compass-core-1.0.3/lib/compass/core/sass_extensions/functions/urls.rb):

module Compass::Core::SassExtensions::Functions::Urls


  def self.has?(base, instance_method)
    Sass::Util.has?(:instance_method, base, instance_method)
  end

  def self.included(base)
    base.send(:include, StylesheetUrl) unless has?(base, :stylesheet_url)
    base.send(:include, FontUrl) unless has?(base, :font_url)
    base.send(:include, ImageUrl) unless has?(base, :image_url)
    base.send(:include, GeneratedImageUrl) unless has?(base, :generated_image_url)
  end

Answer 1

问题：

问题在于，我安装了 Debian 的软件包 ruby-full，以及 Sass 和 Compass 作为 ruby gem，例如使用 gem 命令行工具。

解决方法：

默认情况下，Debian 9.7 (Stretch) 安装了 Ruby 解释器（2.3 版）。包名称是 ruby2.3。为了能够正确编译.scss文件和使用Compass提供的功能，只需要额外安装包ruby-sass和ruby-compass。

已执行的步骤：

I) 首先，使用终端，我继续卸载之前错误安装的库：

我卸载了包 ruby-full:

$ sudo apt purge ruby-full
$ sudo apt autoremove

我卸载了 Sass 和 Compass gems:

$ sudo gem uninstall compass
$ sudo apt autoremove

$ sudo gem uninstall sass
$ sudo apt autoremove

II) 然后我继续安装新的软件包：

我检查了 Debian 默认 Ruby 版本的状态：

$ apt list ruby2.3*
ruby2.3/stable,now 2.3.3-1+deb9u4 amd64 [installed]
ruby2.3-dev/stable,now 2.3.3-1+deb9u4 amd64 [installed,automatic]
ruby2.3-doc/stable,now 2.3.3-1+deb9u4 all [installed,automatic]

我安装了新的软件包：

$ apt update
$ apt install ruby-sass
$ apt install ruby-compass

我检查了两个安装包的版本：

$ sass --version
Sass 3.4.23 (Selective Steve)

$ compass --version
Compass 1.0.3 (Polaris)

我检查了安装的可执行文件的位置：

$ which sass
/usr/bin/sass

$ which compass
/usr/bin/compass

III) 最后，在 Netbeans 中，在选项卡 Tools > Options > HTML/JS > CSS Preprocessors 中，我将 Sass Path 设置为 /usr/bin/sass。

就是这样。 Sass 文件被正确编译并且 Compass 函数被正确识别和调用。

Answer 2

发现此搜索相同的错误消息。通过将本地 sass 的版本从 sass-3.7.4 切换到 sass-3.4.25 (Selective Steve)，我能够解决该问题。
