Question

我在我的应用程序中使用了rspec-rails 2.11.0，但是当我执行rspec spec /出现错误时。这是一堆错误：

有什么问题？这是我的宝石文件https://gist.github.com/3280825

Answer 1

正在发生的事情是您的rspec应用版本与全球环境版本不同。

当你执行rspec时，似乎正在使用来自global的那个。

使其工作的方法是使用bundle exec，如@prusswan所说，它将使用app env执行该命令（使用适当的gems版本等...）

此错误消息提及尝试bundle exec

Answer 2

由于使用了bundler，虽然错误消息显示为“try”bundle exec，但如果您想确保只指定gem版本，必须使用bundle exec运行它在Gemfile/Gemfile.lock中使用。另一种选择是使用binstubs，如here所述。

rspec-rails 2.11.1 + rails 3.2.6
