ruby-on-rails - `rails server` 抛出错误 "cannot load such file"-- sass/logger (LoadError)

Question

rails :3.2.12 ruby :1.9.3p392(openSuse 包) 操作系统:openSuse 12.3

我刚刚运行了 rails new specsheets。这运行干净，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:

    from script/rails:6:in `<main>'

我是 Rails 的新手，所以我不知道该寻找什么。过去，我会转到有问题的目录 (/usr/lib/ruby/gems/1.9.1/gems/) 并确保非根用户和组可以读取所有内容。这一次没有奏效。

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 以反射(reflect)这一点，但仍然出现错误。

我的 gem 文件:

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是空的，所以那里没有什么可报告的。

当使用 sudo 运行时，服务器启动正常。但是，因为我在我自己的/home 目录中有这个，所以不应该这样。

将 sass-rails 放在您的 gemfile 中的 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 sass 有时间设置和自动加载之前调用它。 https://github.com/rails/sass-rails/blob/3-2-stable/lib/sass/rails.rb#L7
