我是否必须手动卸载所有依赖宝石？

Question

我尝试使用该命令卸载datamapper gem uninstall dm-core.

但似乎还需要卸载一大堆依赖宝石.

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？

Answer 1

gem list | cut -d" " -f1 | xargs gem uninstall -aIx 删除所有已安装的红宝石宝石!

Answer 2

据我所知,你是正确的,没有一种简单的方法来内置gem命令来做到这一点.

但是,您可以查看gem-prune,它可以在您删除dm-core后帮助清理您的gem存储库.

Answer 3

我最终制作了一个简单的命令行工具来递归地卸载gem依赖项.

我还递归地向gem卸载依赖项提交了一个rubygems问题.

该rubygems问题已经关闭,在有人提供包含测试的补丁之前不会考虑.

Answer 4

gem cleanup应该做的伎俩。有关详细信息，请参见此处。

Answer 5

for gem in `gem list --no-version`; do
  gem uninstall -aIx $gem
done

对我来说效果最好,不知道为什么

gem list | cut -d" " -f1 | xargs gem uninstall -aIx

在我的系统上不起作用,因为它仍然抱怨...

ERROR:  While executing gem ... (Gem::InstallError)
    cannot uninstall, check `gem list -d some-gem-here`

Answer 6

运行这些卸载时的问题是,它们按顺序排列在宝石列表中,因此如果可以卸载口香糖,那么最终会卡住.运行以下几次,它应该删除允许的所有宝石.

gem list | cut -d" " -f1 | sort -R | xargs -n1 gem uninstall -aIx
