ruby-on-rails - LearnRubyTheHardWay Ex#46 - rake 中止，你应该需要 'minitest/autorun'

Question

我正在学习艰难地学习 Ruby 的示例 46 - 创建项目骨架

链接:http://learnrubythehardway.org/book/ex46.html

所以我创建了如下所示的所有目录:

skeleton/
    NAME.gemspec
    Rakefile
    data
    ext/
    tests/
    bin/
        NAME
    doc/
    lib/
        NAME
        NAME.rb
    lib/NAME
    tests/
        test_NAME.rb

我在 Powershell 的 Skeleton 目录中。

当我按照教程所说的那样运行 rake test 时出现错误。

这是 Powershell 的结果:

PS C:\ruby\learn\projects\skeleton> rake test

书上说我应该得到以下回应:

Loaded suite tests/test_NAME

.
Finished in 0.000226 seconds.

1 tests, 1 assertions, 0 failures, 0 errors

但是我得到了一个错误。我已经搜索修复程序并使用 gem install minitest 但请记住，我没有 gemfile，我不知道是否应该为此类项目。如果我需要一个，我假设教程会这样说。那么我该怎么做才能解决这个问题呢？

Answer 1

您不需要Gemfile。当您在 skeleton 目录时，只需执行以下操作:

gem install 'test-unit'

然后从同一个目录:

rake test

所有测试都会通过。

附言我只是按照您的教程在本地复制了整个内容，并收到了您的错误消息。然后，我安装了 test-unit gem，然后 rake test 正常运行。
