我是否必须手动卸载所有依赖的 gem? [英] Do I have to manually uninstall all dependent gems?

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.

我尝试查找有关gem 卸载"的文档，但似乎没有办法自动卸载依赖项:

I tried finding documentation on "gem uninstall" but there doesn't seem to be a way to uninstall the dependencies automatically:

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.
