关于Rails上的ruby 4：如何在安装email_spec后解决gem依赖冲突

How to resolve a gem dependency conflict after installing email_spec

我只是根据自述文件中的说明安装了与rspec一起使用的email-spec。现在，当我尝试运行测试时(即使未在规范中使用电子邮件规范的方法)，也会收到此错误：

$ rspec spec
Neither Pony nor ActionMailer appear to be loaded so email-spec is requiring ActionMailer.

预先设置bundle exec将使测试运行正常(我仍然会收到Neither Pony nor ActionMailer appear to be loaded so email-spec is requiring ActionMailer通知，但是我想这是另一篇文章的主题)。

这是我的Gemfile。我没有明确地调用minitest，所以我假设它是email_spec和其他东西的依赖项。

我尝试通过将gem 'minitest', '~> 4.7.5'添加到我的:test组来解决冲突，但是仍然遇到相同的错误。

我的问题是：

1)我以前从来不需要加bundle exec。我应该尝试解决冲突而不是在bundle exec之前添加吗？

2)如果对问题1回答"是"，我该怎么做？
