Rails Server引發錯誤“無法加載此類文件” — sass / logger（LoadError）

Question

Rails：3.2.12 Ruby：1.9.3p392（openSuse軟件包）OS：openSuse 12.3

我只是運行rails new specsheets 。 干凈運行，包括捆綁安裝：

當我嘗試啟動WEBrick服務器時，它向我拋出以下內容：

我是Rails的新手，所以我不知道要尋找什么。 過去，我會轉到有問題的目錄（/usr/lib/ruby/gems/1.9.1/gems/），並確保所有內容都可由非root用戶和組讀取。 這次沒有奏效。

我還注意到，我的Gemfile提到了sass-rails 3.2.3，而安裝的版本是3.2.6。 我修改了Gemfile以反映這一點，但仍然收到錯誤。

我的Gemfile：

source 'https://rubygems.org'

gem 'rails', '3.2.12'

# Bundle edge Rails instead:
# gem 'rails', :git => 'git://github.com/rails/rails.git'

gem 'sqlite3'


# Gems used only for assets and not required
# in production environments by default.
group :assets do
  gem 'sass-rails',   '~> 3.2.6'
  gem 'coffee-rails', '~> 3.2.1'

  # See https://github.com/sstephenson/execjs#readme for more supported runtimes
  # gem 'therubyracer', :platforms => :ruby

  gem 'uglifier', '>= 1.0.3'
end

gem 'jquery-rails'

# To use ActiveModel has_secure_password
# gem 'bcrypt-ruby', '~> 3.0.0'

# To use Jbuilder templates for JSON
# gem 'jbuilder'

# Use unicorn as the app server
# gem 'unicorn'

# Deploy with Capistrano
# gem 'capistrano'

# To use debugger
# gem 'debugger'

應用程序目錄下的日志目錄為空，因此沒有要報告的內容。

使用sudo運行時，服務器啟動正常。 但是，由於我在自己的/ home目錄中有此問題，因此情況並非如此。

在您的gemfile中將sass-rails置於rails之上。

sass-rails gem正在嘗試設置記錄器，但找不到Sass::Rails::Logger類。 https://github.com/rails/sass-rails/blob/3-2-stable/lib/sass/rails/railtie.rb#L23

這可能是因為您在有時間設置和自動加載之前調用sass。 https://github.com/rails/sass-rails/blob/3-2-stable/lib/sass/rails.rb#L7
