要求“rspec/autorun”--不适合我

Question

有人能告诉我我做错了什么吗？

~/ruby_programs$ rspec --version
3.0.3

~/ruby_programs$ ruby --version
ruby 2.1.2p95 (2014-05-08 revision 45877) [x86_64-darwin10.0]



~/ruby_programs$ cat my_rspec.rb
require 'rspec/autorun'

describe "require 'rspec/autorun'" do
  it 'should not cause this program to throw an error' do
    true
  end

end

~/ruby_programs$ rspec my_rspec.rb 
.

Deprecation Warnings:

Requiring `rspec/autorun` when running RSpec via the `rspec` command is deprecated. Called from /Users/7stud/ruby_programs/my_rspec.rb:1:in `<top (required)>'.


If you need more of the backtrace for any of these deprecations to
identify where to make the necessary changes, you can configure
`config.raise_errors_for_deprecations!`, and it will turn the
deprecation warnings into errors, giving you the full backtrace.

Answer 1

那是因为RSpec被错过了。你应该做以下几点：

require 'rspec/autorun'

RSpec.describe "require 'rspec/autorun'" do
  it 'should not cause this program to throw an error' do
    true
  end
end

Answer 2

尝试使用$ bundle执行rspec而不是仅使用rspec来执行rspec
