rspec-rails - Spork 无法加载此类文件？

Question

我有一个 spork gem 问题。每次运行 spork 命令时，都会出现这个长错误:

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

/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

我不知道该怎么做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

刚刚系统更新后遇到同样的问题。这是由于缺少对文件的读取权限。

一个简单的 chmod +r 对我有用:

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，我又遇到了这个问题。不幸的是，这一次不是来自访问权限问题，而是来自两次更新之间演变的 gem (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，您还应该检查缺少哪个文件并正确升级相应的 gem。
