我正在尝试使用rails-erd。我最后一次使用它是在二月份,并且工作正常
我尝试使用erd
和bundle exec erd
我收到这个错误。我在另一个项目中有 rails 4,但在这个项目中,我在 gem 文件中使用 rails 3.2.15
Loading application in 'my_app'...
WARN: Unresolved specs during Gem::Specification.reset:
activerecord (>= 3.0)
i18n (>= 0.6.4, ~> 0.6)
multi_json (~> 1.3)
tzinfo (~> 0.3.37)
WARN: Clearing out unresolved specs.
Please report a bug if this causes problems.
Failed: Gem::LoadError: You have already activated activesupport 4.0.0, but your Gemfile requires activesupport 3.2.15. Using bundle exec may solve this.
这是什么意思,我该如何解决?
