Question

我3个月前开始使用rspec并且我在sinatra项目中使用它（使用ruby 2.1.1）...

我的规格中没有错误（它们已成功在其他计算机上运行）但是在我自己运行它时，每个示例都有这个...

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

我使用了这个链接（https://github.com/rspec/rspec-core/issues/754），但它不适用于我（我的应用程序位于名为projects的文件夹中）...

我也试过使用ruby 2.0.0，但这是同样的问题......

我很乐意阅读任何有用的文章......谢谢

问题是你的ruby加载了一个版本的rspec或rspec-mock，它与你的代码不对应。

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

通过这种方式，您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。所以我建议每个项目使用它。

由于rspec-mocks＃setup，RSpec.configure无法正常工作并且示例失败
