gem - 指南针找不到奇点

Question

指南针框架无法加载/找到“singularitygs”框架/扩展：

我通过 RubyGem 安装了这些软件包：

gem list compass && gem list singularity && gem list breakpoint

这给了我以下信息：

*** LOCAL GEMS ***

compass (1.0.0.alpha.18)
compass-core (1.0.0.alpha.17)
compass-import-once (1.0.2)

*** LOCAL GEMS ***

singularitygs (1.1.2)

*** LOCAL GEMS ***

breakpoint (2.4.1)

compass:dev我的 Gruntfile的任务：

compass:
  dev:
    options:
      trace: true
      require: ['singularitygs']
      sassDir: '<%= dir.sass %>'
      cssDir: '<%= dir.css %>'
      environment: 'development'

结果：

Running "compass:dev" (compass) task
LoadError on line 51 of /Library/Ruby/Site/1.8/rubygems/core_ext/kernel_require.rb: no such file to load -- singularitygs
Run with --trace to see the full backtrace
Warning: ↑ Use --force to continue.

Aborted due to warnings.

接下来我尝试了一个config.rb文件：

compass:
  dev:
    options:
      trace: true
      config: 'config.rb'
      sassDir: '<%= dir.sass %>'
      cssDir: '<%= dir.css %>'
      environment: 'development'

具有以下内容：

require 'singularitygs'

就是这样，结果如下：

因此，我检查了 Compass 是否compass frameworks --trace在另一个目录中有该框架：

Available Frameworks & Patterns:

  * blueprint
    - blueprint/basic      - A basic blueprint install that mimics the actual blueprint css.
    - blueprint/buttons    - Button Plugin
    - blueprint/link_icons - Icons for common types of links
    - blueprint/project    - The blueprint framework.
    - blueprint/semantic   - The blueprint framework for use with semantic markup.
  * compass
    - compass/ellipsis     - Plugin for cross-browser ellipsis truncated text.
    - compass/extension    - Generate a compass extension.
    - compass/pie          - Integration with http://css3pie.com/
    - compass/project      - The default project layout.

如果我在文件compass frameworks --trace所在的根目录中执行相同的命令config.rb，我将得到相同的错误：

  /usr/bin/compass:23:in `load'
  /usr/bin/compass:23

我不知道，我可以尝试解决这个问题。此外，我卸载并安装了所有 gem 文件但没有成功。也许这是错误的宝石环境gem env？

感谢您的帮助和提示，大流士

Answer 1

Singularity 1.1.2 与 Compass 1.0.0 不兼容。不过，我们有 Singularity 1.2.0 的预发布版本。

Gem 兼容性问题正是我们推荐使用 Bundler来管理 gem 版本的原因。如果您想在 Compass 1.0.0 中使用 Singularity，请执行以下操作：

1. (sudo) gem install bundler

2. Gemfile在项目的根目录下创建一个文件 ，并添加以下内容：

   source 'http://rubygems.org'
   gem 'singularitygs', '~>1.2.0.rc.6'
   

3. 跑bundle install --path vendor

4. 忽略vendor版本控制系统中的目录（如果使用 Git，请添加./vendor到.gitignore文件中）
5. 添加bundleExec: true到您的compass:dev Grunt 任务

Answer 2

我将 Ruby 从降级2.0.0到1.9.3viarbenv并解决了问题。
