我在 3 个月前开始使用 rspec，我正在一个 sinatra 项目中使用它（使用 ruby​​ 2.1.1）...

我的规格没有错误（它们已在其他计算机上成功运行），但是在我自己运行它们时，我为每个示例都得到了这个......

===========================

我使用了这个链接（https://github.com/rspec/rspec-core/issues/754），但它对我不起作用（我的应用程序位于名为项目的文件夹中）......

我也尝试过使用 ruby​​ 2.0.0 但这是同样的问题......

我很乐意阅读有关它的任何有用的文章...谢谢

问题是您的 ruby​​ 加载了与您的代码不对应的 rspec 或 rspec-mock 版本。

所以要修复这个沙箱你的宝石。

#clean up
$ rm -rf .bundle Gemfile.lock bin vendor

#install
$ bundle install --binstubs --path vendor

#run
$ bundle exec ruby yourfile.rb
$ bin/rackup

有了这个，您可以确保您的项目使用来自 gemfiles 的指定 gem，而不是任何可以令人惊讶地安装在您的系统上的 gem。这也可以防止疯狂的加载路径错误。所以我建议在每个项目中都使用它。
