我想做testfirst.org練習，儘管由於版本問題/缺乏知識，我似乎無法到達起跑線。 。Testfirst.org - 瞭解ruby課程 - Rspec問題無法解決
在開始時，你必須運行測試$耙
我得到了下面的錯誤..
(in /home/arno/learn_ruby)
rake aborted!
Gem::MissingSpecError: Could not find 'rspec' (~> 2) among 94 total
gem(s)
Checked in
'GEM_PATH=/home/arno/.gem/ruby/2.4.0:/home/arno/.rbenv/
versions/2.4.0/lib/ruby/gems/2.4.0', execute `gem env` for more
information
/home/arno/learn_ruby/Rakefile:2:in `<top (required)>'
(See full trace by running task with --trace)
然後我試圖卸載rspec的。然後我嘗試安裝一個小於3的版本。這也沒有奏效。現在我有版本2.9和3.2安裝，但同樣的錯誤依然存在..
我當時也捆綁安裝和捆綁更新......事情發生了轉變，儘管仍然沒有工作..
下面是最新的錯誤當我運行測試$耙..
(in /home/arno/learn_ruby)
rake aborted!
NoMethodError: undefined method `last_comment' for #

這裏是Rake文件..
# This Rakefile has all the right settings to run the tests inside
each lab
gem 'rspec', '~>2'
require 'rspec/core/rake_task'
task :default => :spec
desc "run tests for this lab"
RSpec::Core::RakeTask.new do |task|
lab = Rake.application.original_dir
task.pattern = "#{lab}/*_spec.rb"
task.rspec_opts = [ "-I#{lab}", "-I#{lab}/solution", '-f
documentation', '-r ./rspec_config']
task.verbose = false
end
