Rails Server引发错误“无法加载此类文件” — sass / logger（LoadError）

Question

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

我只是运行rails new specsheets 。 干净运行，包括捆绑安装：

当我尝试启动WEBrick服务器时，它向我抛出以下内容：

我是Rails的新手，所以我不知道要寻找什么。 过去，我会转到有问题的目录（/usr/lib/ruby/gems/1.9.1/gems/），并确保所有内容都可由非root用户和组读取。 这次没有奏效。

我还注意到，我的Gemfile提到了sass-rails 3.2.3，而安装的版本是3.2.6。 我修改了Gemfile以反映这一点，但仍然收到错误。

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'

应用程序目录下的日志目录为空，因此没有要报告的内容。

使用sudo运行时，服务器启动正常。 但是，由于我在自己的/ home目录中有此问题，因此情况并非如此。

在您的gemfile中将sass-rails置于rails之上。

sass-rails gem正在尝试设置记录器，但找不到Sass::Rails::Logger类。 https://github.com/rails/sass-rails/blob/3-2-stable/lib/sass/rails/railtie.rb#L23

这可能是因为您在有时间设置和自动加载之前调用sass。 https://github.com/rails/sass-rails/blob/3-2-stable/lib/sass/rails.rb#L7
