我在我的应用程序中使用 rspec-rails 2.11.0，但是当我执行 rspec spec/ 时发生了错误。这是一堆错误：

发生的事情是您的 rspec 应用程序版本与您在全局环境中的版本不同。

当您执行 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@prusswan 所说的，它将使用应用程序环境执行该命令（使用适当的 gems 版本等。）

错误消息还提到尝试bundle exec

由于使用了 bundler，尽管错误消息显示为 "try" ，但如果您想确保仅使用中指定的 gem 版本bundle exec，您确实Gemfile/Gemfile.lock必须使用 bundle exec 运行它。另一种选择是使用 binstubs，如此处所述。
