问题描述
我尝试使用命令 gem uninstall dm-core
卸载 datamapper.
I tried to uninstall datamapper using the command gem uninstall dm-core
.
但是好像还需要卸载一大堆依赖的gem.
But it seems that a whole bunch of dependent gems also need to be uninstalled.
C:>gem uninstall dm-core
You have requested to uninstall the gem:
dm-core-0.9.11
dm-migrations-0.9.11 depends on [dm-core (= 0.9.11)]
dm-cli-0.9.11 depends on [dm-core (= 0.9.11)]
dm-serializer-0.9.11 depends on [dm-core (= 0.9.11)]
dm-timestamps-0.9.11 depends on [dm-core (= 0.9.11)]
dm-aggregates-0.9.11 depends on [dm-core (= 0.9.11)]
dm-types-0.9.11 depends on [dm-core (= 0.9.11)]
dm-is-tree-0.9.11 depends on [dm-core (= 0.9.11)]
dm-observer-0.9.11 depends on [dm-core (= 0.9.11)]
dm-validations-0.9.11 depends on [dm-core (= 0.9.11)]
If you remove this gems, one or more dependencies will not be met.

我错过了什么吗?
推荐答案
据我所知,你是对的,gem 命令没有内置的简单方法可以做到这一点.
As far as I know you're correct, there is not an easy way built-in to the gem command to do this.
但是,您可以查看 gem-prune,它可以帮助您在删除 dm-core 后清理您的 gem 存储库.
However, you can check out gem-prune which can help clean up your gem repository after you've removed dm-core.
