ruby-on-rails - 无法让 rake spec 工作

Question

我正在按照教程学习 Ruby + Rails，但无法让 rspec 为我工作。

我正在进行“我们的第一次测试”，当我运行 rake spec 时，出现以下错误:

harley-alexanders-macbook-pro:loccasions Harley$ rake spec

Tasks: TOP => spec
(See full trace by running task with --trace)

我多次发现这个问题是过时的 gem ，但我已经更新了所有 gem 和我的 Gemfile 以反射(reflect)这一点。

我知道“特征”是 capybara gem 的一种方法，用于匹配场景等。我在我的 spec/spec_helber.rb 文件中包含了 require('rspec/capybara')以及在我的 Gemfile 中。

我做错了什么!？

干杯，

改为尝试:

bundle exec rake spec
