Spork无法加载这样的文件？

Question

我有一个spork gem问题.每次我运行spork命令时都会遇到这个长错误:

evan@TheBeast-Computer:~/rails_projects/sample_app$ spork

/home/evan/.rvm/gems/ruby-1.9.3-p194/bin/spork:23:in `<main>'

这是我的Gemfile:

source 'https://rubygems.org'

gem 'rails', '3.2.5'

gem 'sqlite3'

group :assets do
  gem 'sass-rails',   '~> 3.2.3'
  gem 'coffee-rails', '~> 3.2.1'

  gem 'uglifier', '>= 1.0.3'
end

gem 'jquery-rails'

group :development, :test do
  gem 'rspec-rails',    ">= 2.0.1"
end

group :test do
  gem 'rspec-rails', '>= 2.0.1'
  gem 'spork', '>= 0.8.4'
end

我无法做什么或如何描述我的情况.但是我在Ruby on Rails 3教程书中看到的结果显示:

$ spork
Using RSpec
Loading Spork.prefork block...
Spork is ready and listening on 8989!

Answer 1

系统更新后遇到同样的问题.这是由于文件上缺少读取权限.

一个简单的chmod + r为我工作:

sudo chmod +r /home/evan/.rvm/gems/ruby-1.9.3-p194/gems/spork-0.9.2/bin/spork

编辑

更新到Rails 3.2.9和Ruby 1.9.3-p327时,我又遇到了问题.不幸的是,这次并非来自访问权问题,而是来自两个更新之间发展的宝石(应该是完全透明的).因此,如果您遇到此问题,如果您没有访问权限权限问题,则还应检查哪个文件丢失,并正确升级相应的gem.
